    In the era of immune checkpoint inhibitors for cancers, the need for prognostic biomarkers to identify patients most likely to achieve a durable response has become increasingly more relevant. Tumour-infiltrating lymphocytes (TILs) have gained significant interest, as they can be evaluated using standard haematoxylin and eosin-stained slides, making it a widely accessible and cost-effective biomarker. In addition to their practicality, TILs provide prognostic insights into the interplay between the immune system and tumour cells. While the morphological assessment of TILs has been standardised in breast cancer, comprehensive guidelines for their evaluation in gastro-oesophageal carcinomas (GEC) are still lacking. This narrative review examines the current literature on the composition, clinical implications and therapeutic utility of TILs in GEC. These insights are used to propose a framework with recommendations for standardised evaluation and reporting of TILs in GEC, while also highlighting pitfalls specific to GEC pathology. These recommendations serve as a vital first step towards the widespread use and validation of TILs as a biomarker.

    The identification and accurate diagnosis of focal liver lesions are important in modern medicine, where diagnostic radiology plays an essential role. This review aimed to examine the hyperechogenicity and histopathological features of focal liver lesions. Hyperechogenic liver lesions can be either benign or malignant. Evidence shows that hyperechogenicity is caused by factors such as fat deposition, sinusoidal dilation, peliotic changes, and pseudoglandular patterns. Fat deposition is a common cause of increased echogenicity in hepatocellular carcinoma (HCC). Meanwhile, sinusoidal dilation and peliotic changes are more frequently observed in larger HCC nodules. Pseudoglandular patterns, characterized by the reflection of ultrasound waves at the walls of numerous acini, are associated with hyperechogenicity in well-to-moderately differentiated HCCs. Moreover, this review comprehensively examined the histological features that may cause hyperechogenic internal echoes in not only HCCs but also localized liver lesions (metastases of adenocarcinoma and neuroendocrine neoplasm, intrahepatic cholangiocarcinoma, cavernous hemangioma, focal nodular hyperplasia, and angiomyolipoma). To make an accurate diagnosis and provide appropriate management, it is important to understand the histopathological basis for hyperechogenicity in focal liver lesions. By maximizing the accuracy of imaging studies and enhancing the radiology-pathology correlation, unnecessary biopsies can be avoided, thereby reducing potential complications and mortality. This review can help facilitate the effective management of patients with focal liver lesions, thereby resulting in timely and appropriate treatment decision-making.

    Background and study aims Gastric adenocarcinoma of the fundic gland type (GA-FG) is characterized by an elevated lesion with vessel dilation exhibiting branching architecture (DVBA). However, this feature is also found in fundic gland polyps (FGPs), posing a challenge in their differentiation. In this study, we aimed to investigate the clinicopathological features of gastric elevated lesions with DVBA and assess the efficacy of the white ring sign (WRS) as a novel marker for distinguishing between FGPs and GA-FGs. Methods We analyzed 159 gastric elevated lesions without DVBA and 51 gastric elevated lesions with DVBA, further dividing the latter into 39 in the WRS-positive group and 12 in the WRS-negative group. The clinicopathological features, diagnostic accuracy, and inter-rater reliability were analyzed. Results Univariate and multivariate analyses for gastric elevated lesions with DVBA identified the histological type consistent with FGPs and GA-FGs, along with the presence of round pits in the background gastric mucosa, as independent predictors. FGPs were present in 92.3% (36/39) of the WRS-positive group and GA-FGs were observed in 50.0% (6/12) of the WRS-negative group. WRS positivity and negativity exhibited high diagnostic accuracy, with 100% sensitivity, 80.0% specificity, and 94.1% accuracy for FGPs, and 100% sensitivity, 86.7% specificity, and 88.2% accuracy for GA-FGs. Kappa values for WRS between experts and nonexperts were 0.891 and 0.841, respectively, indicating excellent agreement. Conclusions WRS positivity and negativity demonstrate high diagnostic accuracy and inter-rater reliability for FGPs and GA-FGs, respectively, suggesting that WRS is a useful novel marker for distinguishing between FGPs and GA-FGs.

    INTRODUCTION: Since patients with pharyngeal squamous cell carcinoma (SCC) often have multiple pharyngeal lesions, evaluation of pharyngeal lesions before endoscopic resection (ER) is important. However, detailed endoscopic observation of the entire pharyngeal mucosa under conscious sedation is difficult. We examined the usefulness of endoscopic surveillance with narrow band imaging (NBI) and lugol staining for detection of pharyngeal sublesions during ER for pharyngeal SCC under general anesthesia (endoscopic surveillance during treatment; ESDT). METHODS: From January 2021 through June 2022, we examined 78 patients who were diagnosed with superficial pharyngeal SCC and underwent ER. They underwent the ESDT and for patients who were diagnosed with new lesions of pharyngeal SCC or high-grade dysplasia (HGD) that were not detected in the endoscopic examination before treatment, ER were performed simultaneously for new lesions and the main lesions. The primary endpoint of this study was the detection rate of new lesions of pharyngeal SCC or HGD in the ESDT. RESULTS: Fifteen of the 78 patients were diagnosed as having undetected new pharyngeal lesions in the ESDT and 10 (12.8%) (95% CI 6.9-22.2%) were histopathologically confirmed to have new lesions of pharyngeal SCC or HGD. Among the 13 lesions of SCC or HGD, 8 were found by NBI observation; however, 5 were undetectable using NBI but detectable by lugol staining. All of the 13 lesions had endoscopic findings of pink color sign on lugol staining. CONCLUSIONS: Endoscopic surveillance for pharyngeal sublesions during ER for pharyngeal SCC is feasible and useful.

    We herein report a case of a branch-duct intraductal papillary mucinous neoplasm (IPMN) with rapidly developing intracystic xanthogranulomatous nodules. A unilocular cystic lesion without a mural nodule was found in the pancreatic tail of a 69-year-old man. Ten months later, multiple mural nodules emerged unexpectedly within the cyst, and the patient underwent distal pancreatectomy. Based on immunohistochemical studies and a molecular analysis, we diagnosed him with branch-duct IPMN of the gastric immunophenotype. Fragility of the pancreatic duct mucosa and consequent exposure of the wall to pancreatic juice might have caused marked granulation nodule formation in the cyst lumen.

    BACKGROUND: Prostate cancer is often a slowly progressive indolent disease. Unnecessary treatments from overdiagnosis are a significant concern, particularly low-grade disease. Active surveillance has being considered as a risk management strategy to avoid potential side effects by unnecessary radical treatment. In 2016, American Society of Clinical Oncology (ASCO) endorsed the Cancer Care Ontario (CCO) Clinical Practice Guideline on active surveillance for the management of localized prostate cancer. METHODS: Based on this guideline, we developed a deep learning model to classify prostate adenocarcinoma into indolent (applicable for active surveillance) and aggressive (necessary for definitive therapy) on core needle biopsy whole slide images (WSIs). In this study, we trained deep learning models using a combination of transfer, weakly supervised, and fully supervised learning approaches using a dataset of core needle biopsy WSIs (n=1300). In addition, we performed an inter-rater reliability evaluation on the WSI classification. RESULTS: We evaluated the models on a test set (n=645), achieving ROC-AUCs of 0.846 for indolent and 0.980 for aggressive. The inter-rater reliability evaluation showed s-scores in the range of 0.10 to 0.95, with the lowest being on the WSIs with both indolent and aggressive classification by the model, and the highest on benign WSIs. CONCLUSION: The results demonstrate the promising potential of deployment in a practical prostate adenocarcinoma histopathological diagnostic workflow system.

    The pathological differential diagnosis between breast ductal carcinoma in situ (DCIS) and invasive ductal carcinoma (IDC) is of pivotal importance for determining optimum cancer treatment(s) and clinical outcomes. Since conventional diagnosis by pathologists using microscopes is limited in terms of human resources, it is necessary to develop new techniques that can rapidly and accurately diagnose large numbers of histopathological specimens. Computational pathology tools which can assist pathologists in detecting and classifying DCIS and IDC from whole slide images (WSIs) would be of great benefit for routine pathological diagnosis. In this paper, we trained deep learning models capable of classifying biopsy and surgical histopathological WSIs into DCIS, IDC, and benign. We evaluated the models on two independent test sets (n= 1382, n= 548), achieving ROC areas under the curves (AUCs) up to 0.960 and 0.977 for DCIS and IDC, respectively.

    Liquid-based cytology (LBC) for cervical cancer screening is now more common than the conventional smears, which when digitised from glass slides into whole-slide images (WSIs), opens up the possibility of artificial intelligence (AI)-based automated image analysis. Since conventional screening processes by cytoscreeners and cytopathologists using microscopes is limited in terms of human resources, it is important to develop new computational techniques that can automatically and rapidly diagnose a large amount of specimens without delay, which would be of great benefit for clinical laboratories and hospitals. The goal of this study was to investigate the use of a deep learning model for the classification of WSIs of LBC specimens into neoplastic and non-neoplastic. To do so, we used a dataset of 1605 cervical WSIs. We evaluated the model on three test sets with a combined total of 1468 WSIs, achieving ROC AUCs for WSI diagnosis in the range of 0.89-0.96, demonstrating the promising potential use of such models for aiding screening processes.

    Signet ring cell carcinoma (SRCC) of the stomach is a rare type of cancer with a slowly rising incidence. It tends to be more difficult to detect by pathologists, mainly due to its cellular morphology and diffuse invasion manner, and it has poor prognosis when detected at an advanced stage. Computational pathology tools that can assist pathologists in detecting SRCC would be of a massive benefit. In this paper, we trained deep learning models using transfer learning, fully-supervised learning, and weakly-supervised learning to predict SRCC in Whole Slide Images (WSIs) using a training set of 1,765 WSIs. We evaluated the models on two different test sets (n = 999, n = 455). The best model achieved a ROC-AUC of at least 0.99 on all two test sets, setting a top baseline performance for SRCC WSI classification.

    BACKGROUND: X-linked inhibitor of apoptosis protein (XIAP) deficiency is one of inborn errors of immunity characterized by recurrent hemophagocytic lymphohistiocytosis (HLH) and refractory inflammatory bowel disease (IBD) mimicking Crohn's disease (CD). The aim of this study is to make accurate diagnosis of XIAP deficiency based on genetic and XIAP expression studies and to investigate endoscopic findings shared by patients with this disease. METHODS: Four male patients with recurrent HLH and long-term refractory IBD were studied for the diagnosis of XIAP deficiency. Parallelly, endoscopic findings of the four patients were also studied. RESULTS: These four patients were diagnosed with XIAP deficiency based on the absent XIAP expression in cultured T-cell blasts. Sequence analysis of the responsible gene, XIAP, demonstrated two novel nonsense mutations of p.Gln114X and p.Glu25X, and a previously reported nonsense mutation of p.Arg381X. Although no mutations in the coding region were detected in the fourth patient, further studies demonstrated a novel 2199 bp deletion encompassing non-coding exon 1, presumably affecting transcription and stability of XIAP mRNA. All of the patients eventually underwent hematopoietic stem cell transplantation, leading to a complete or partial remission of IBD. These four patients shared an endoscopic finding of multiple wide and longitudinal ulcers with straight and non-raised edge in the colon. CONCLUSIONS: XIAP expression in T-cell blasts could facilitate the diagnosis of this disease especially with causal mutations in non-coding regions.

    BACKGROUND AND OBJECTIVE: The diagnosis of interstitial lung diseases (ILDs) often relies on the integration of various clinical, radiological, and histopathological data. Achieving high diagnostic accuracy in ILDs, particularly for distinguishing usual interstitial pneumonia (UIP), is challenging and requires a multidisciplinary approach. Therefore, this study aimed to develop a multimodal artificial intelligence (AI) algorithm that combines computed tomography (CT) and histopathological images to improve the accuracy and consistency of UIP diagnosis. METHODS: A dataset of CT and pathological images from 324 patients with ILD between 2009 and 2021 was collected. The CT component of the model was trained to identify 28 different radiological features. The pathological counterpart was developed in our previous study. A total of 114 samples were selected and used for testing the multimodal AI model. The performance of the multimodal AI was assessed through comparisons with expert pathologists and general pathologists. RESULTS: The developed multimodal AI demonstrated a substantial improvement in distinguishing UIP from non-UIP, achieving an AUC of 0.92. When applied by general pathologists, the diagnostic agreement rate improved significantly, with a post-model κ score of 0.737 compared to 0.273 pre-model integration. Additionally, the diagnostic consensus rate with expert pulmonary pathologists increased from κ scores of 0.278-0.53 to 0.474-0.602 post-model integration. The model also increased diagnostic confidence among general pathologists. CONCLUSION: Combining CT and histopathological images, the multimodal AI algorithm enhances pathologists' diagnostic accuracy, consistency, and confidence in identifying UIP, even in cases where specialised expertise is limited.

    BACKGROUND: Endocytoscopy (ECS) enables microscopic observation in vivo for the gastrointestinal mucosa; however, there has been no prospective study in which the diagnostic accuracy of ECS for lesions that have not yet undergone histological diagnosis was evaluated. We conducted a surveillance study for patients in a high-risk group of esophageal squamous cell carcinoma (ESCC) and evaluated the in vivo histological diagnostic accuracy of ECS. METHODS: This study was a multicenter prospective study. We enrolled 197 patients in the study between September 1, 2019 and November 30, 2020. The patients first underwent white light imaging and narrow band imaging, and ultra-high magnifying observation was performed if there was a lesion suspected to be an esophageal tumor. Endoscopic submucosal dissection (ESD) was later performed for lesions that were diagnosed to be ESCC by ECS without biopsy. We evaluated the diagnostic accuracy of ECS for esophageal tumorous lesions. RESULTS: ESD was performed for 37 patients (41 lesions) who were diagnosed as having ESCC by ECS, and all of them were histopathologically diagnosed as having ESCC. The sensitivity [95% confidence interval (CI)] was 97.6% (87.7-99.7%), specificity (95% CI) was 100% (92.7-100%), diagnostic accuracy (95% CI) was 98.9% (94.0-99.8%), positive predictive value (PPV) (95% CI) was 100% (91.4-100%) and negative predictive value (NPV) (95% CI) was 98.0% (89.5-99.7%). CONCLUSIONS: ECS has a high diagnostic accuracy and there were no false positives in cases diagnosed and resected as ESCC. Optical biopsy by using ECS for esophageal lesions that are suspected to be tumorous is considered to be sufficient in clinical practice.

    The widespread use of Helicobacter pylori eradication therapy in recent years has reduced the H. pylori infection rate, indicating that gastric cancer cases diagnosed in the future may be H. pylori-naïve. The typical endoscopic presentation of signet-ring cell carcinoma, which accounts for the majority of H. pylori-naïve gastric cancer cases, is a discolored, flat, or depressed lesion; it is rarely presented as an elevated lesion. In this study, we treated a patient with elevated signet-ring cell carcinoma in an H. pylori-naïve stomach. Histopathological testing after endoscopic submucosal dissection showed proliferation of fibromuscular tissue in the tumor, which may have caused the formation of the elevated lesion.

    <p>A 71-year-old man with the chief complaint of appetite loss had previously visited a doctor and had been diagnosed with esophagogastric junction cancer. Because of multiple fluid-filled blisters and erosions on the trunk and extremities, the patient was referred to our hospital for further detailed examination. Based on skin biopsy findings, he was diagnosed with bullous pemphigoid. Blood tests revealed advanced hypoproteinemia. From the clinical course, the onset of bullous pemphigoid was suspected to be a symptom of the malignant tumor. After steroid therapy and preoperative nutritional intervention, distal esophagectomy and proximal gastrectomy were performed. The pathological diagnosis was papillary adenocarcinoma, pStage IIIA. The postoperative course was uneventful. Recent examinations performed four months after surgery showed no evidence of recurrence. Furthermore, the skin symptoms and nutritional status improved after surgery. Bullous pemphigoid is an autoimmune bullous disease and has frequently been reported to be associated with malignant tumors ; however, their relationship was unclear. In this case, although the patient showed good response to steroid therapy, his skin symptoms further improved after tumor resection ; this suggested a strong association between bullous pemphigoid and maligmant tumor. In this study, we also discussed the clinical course and treatment strategy.</p>

    <p>A 53-year-old man with a history of childhood epilepsy and mental retardation presented to a hospital because of nausea and vomiting. He was diagnosed with intestinal obstruction and treated conservatively by the previous doctor for two days, but his condition became worse and he was referred to our hospital for more detailed examinations. Abdominal plain radiography showed a dilated large intestine and an air fluid level. Contrast-enhanced abdominal computed tomography scan showed remarkable intestinal dilatation ascites, and a whirl sign which suggests intestinal torsion, in the right lower quadrant of abdomen. Intestinal obstruction caused by volvulus was diagnosed and a laparotomy was performed. Intraoperative observation showed a markedly dilated colon with caecal and sigmoid volvulus, and we performed subtotal colectomy. After the surgery, paralytic ileus was prolonged. He was discharged from our hospital approximately three months after the surgery. Intestinal volvulus is a condition in which the intestinal tract is twisted with the mesentery. Intestinal volvulus usually occurs at a single site, and it is rare that multiple torsions occur simultaneously. We report a very rare case of intestinal obstruction due to synchronous caecal and sigmoid volvulus.</p>

    <p>A 70-year-old man was admitted to our hospital with right-sided inguinal pain and abdominal fullness. He was diagnosed as having ileus, and we inserted an ileus tube. Ileus tube angiography showed stenosis of a segment of the small intestine. Following improvement of his symptoms, we removed the ileus tube, and oral intake was resumed. However, the symptom of abdominal fullness recurred. Laparoscopic examination was performed, which showed stenosis of a segment of the small intestine and a right-sided femoral hernia. We resected the small intestine including the stenotic segment. Histopathological findings revealed scarring changes in the small intestine because of the stenosis, which led to the suspicion of ischemic stenosis of the small intestine. Two months later, we performed laparoscopic femoral hernia repair for the right-sided femoral hernia. Postoperatively, the patient reported no symptoms, such as inguinal swelling or ileus. </p><p>Clinicians should consider the possibility of development of ischemic stenosis of the small intestine after hernia incarceration.</p>

    <p>A 79-year-old woman who had undergone laparoscopic right hemicolectomy for ascending colon cancer 2 years earlier was admitted to our hospital. Histopathology revealed a T4b(SI, retroperitoneal)N0M0 stageⅡtumor, with vascular invasion (v2). She was administered 8 courses of Xeloda after the surgery. A follow-up CT performed 2 years after the surgery showed an irregular mass in the uterine body showing ring enhancement, and a mass in the pelvic floor. FDG-PET showed increased uptake by both the mass in the uterine body and that in the pelvic floor. We suspected the lesions as being metastases from ascending colon cancer, or as a primary tumor of the uterus with seeding. Extensive total hysterectomy and excision of the mass in the pelvic floor were performed. The mass was in the retroperitoneal region beyond the peritoneum reversing section . Pathological examination revealed that both the masses in the uterine body and retroperitoneal were metastases from ascending colon cancer. At present, 20 days since the surgery, the patient has shown a favorable course. We report this case, as metachronous metastases from the ascending colon cancer to the uterine body and retroperitoneum are rare.</p>

    症例は50歳代男性で、健診の上部消化管内視鏡検査にて胃病変を指摘された。抗H.pylori-IgG抗体陰性であった。隆起部と陥凹部の間に腺管の丈や密度などの差異が予測されたが表面構造は残存しており、病変全体として高分化型腺癌と診断した。病理学的所見は、病変口側部では病変は粘膜表層に分布し、深部には非腫瘍腺管が残存した。腫瘍腺管は一部で不規則な分岐を伴う管状構造を示し、非腫瘍部と比べてわずかに陥凹していた。病変中央部では口側と比べて上方への発育傾向が強く、一部の腫瘍腺管は乳頭状に近い構造を呈した。NBIで観察した腫大したvilli様構造はこれらの所見を反映したものと推察した。粘膜深層には、非腫瘍性の胃底腺や偽幽門腺化生腺管が残存した。病変肛門部では丈の低い管状の異型腺管が密に配列し、深部には非腫瘍性の胃底腺が残存していたが近傍の非腫瘍部と比べるとその量は減少していた。これらはNBIで細かいvilli様構造として捉えられた陥凹部の所見に相当すると考えられた。

    <p>A 19-year-old male with diarrhea, abdominal pain, fever, and elevated C-reactive protein (CRP) levels was admitted to our hospital. Endoscopic examination and small intestinal contrast radiography revealed multiple longitudinal ulcers in the large intestine and ileum. A specimen biopsied from one of these ulcers revealed non-caseating epithelioid cell granuloma. He also had a draining anal fistula. Plain chest computed tomography (CT) and abdominal contrast-enhanced CT did not reveal any vascular abnormality. A diagnosis of Crohn's disease was made, and infliximab was administered. Following infliximab administration, the diarrhea and abdominal pain disappeared, longitudinal ulcers in the large intestine healed (as evidenced by endoscopic examination), and his anal lesion improved. However, fever and elevated CRP levels persisted. With the concomitant use of prednisolone, the fever and elevation of CRP levels eventually improved, and the patient was discharged. Both, however, recurred as the patient was weaned off prednisolone treatment; consequently, he was re-hospitalized. Contrast-enhanced CT upon re-admission revealed stenoses of the right renal artery, left common carotid artery, and left subclavian artery. In addition to Crohn's disease, the patient was diagnosed with co-existing Takayasu's arteritis.</p>

    <b>Purpose</b>: We compared liver stiffness by transient elastography and visual evaluation by B-mode image against the liver fibrosis stage of liver biopsy.<br><b>Methods</b>: 121 examples which liver biopsy was implemented at the same moment with transient elastography between Oct 2012 and Dec 2013. 61 examples of males and 60 examples of females, average age 57.2&plusmn;12.4 years old. Breakdown of the cause of hepatic disorder is 12 examples of hepatitis B virus (HBV), 59 examples of hepatitis C virus (HCV), 22 examples of non-alcoholic steatohepatitis (NASH), 11 examples of primary biliary cirrhosis (PBC), 7 examples of autoimmune hepatitis (AIH), 2 examples of alcoholic, 2 examples of drug-induced, 2 examples of fatty liver, 4 examples with no known cause. Breakdown of the classification of liver fibrosis stage by liver biopsy is 11 examples of F0, 44 examples of F1, 35 examples of F2, 16 examples of F3, 15 examples of F4. Examination items are (1) contradistinction of liver stiffness and the result of liver biopsy, (2) contradistinction of visual evaluation and the result of liver biopsy. Visual evaluation was conducted under an agreement of 3 sonographers without any information of each patients, classifying B-mode image into 1 (normal～chronic hepatitis; CH), 2 (CH), 3 (Pre liver cirrhosis; PreLC), 4 (LC).<br><b>Results</b>: (1) Respective average value of liver stiffness is F0; 5.5&plusmn;1.4 kPa (median 5.2 kPa), F1; 5.8&plusmn;2.3 kPa (median 5.6 kPa), F2; 9.3&plusmn;5.5 kPa (median 7.7 kPa), F3; 14.8&plusmn;8.0 kPa (median 13.0 kPa), F4; 26.7&plusmn;11.3 kPa (median 24.0 kPa) and observed elevation of liver stiffness as liver fibrosis stage elevated. It respectively showed a significant difference between F1–F2, F2–F3, F3–F4 (p<0.005, p<0.05, p<0.05).<br>(2) 83 examples (68.6%) are accordant results of both visual evaluation and liver fibrosis stage. On the other hand, 38 examples (31.4%) are vastly different results and they tend to be low level of liver fibrosis stage. Especially, we could recognize 12 examples (9.9%) as huger difference and the breakdown of each reason of hepatic disorder is HBV 1 example, HCV 2 examples, AIH 4 examples, PBC 1 example, PBC＋AIH 1 example, NASH 2 examples, for unknown reason 1 example and could also recognize lots of non-viral hepatic disorder.<br><b>Conclusion</b>: Both liver stiffness and visual evaluation showed high diagnostic accuracy even simple substance. But the score of liver stiffness varied widely even in liver fibrosis stage where is same with liver stiffness. And there existed overlaps between liver fibrosis stages laid side-by-side. With that in mind, we have to estimate liver fibrosis carefully. Transitional period from normal liver to chronic hepatitis and non-viral hepatic disorder tended to show gap with visual evaluation. It is important to determine, grasping that both tissue characterization and image characteristics with respect to each reasons of hepatic disorder. If possible, we are able to realize higher-accuracy non-invasive diagnosis of liver fibrosis, with using liver stiffness and visual evaluation together for transitional period from normal liver to chronic hepatitis and non-viral hepatic disorder.

    <b><i>Background</i></b> : Matrix-producing carcinoma (MPC) of the breast is a rare subtype of breast cancer, accounting for 0.03 to 0.2% of all breast cancers.<br>We report a case of MPC and its cytopathological features.<br><b><i>Case</i></b> : A 53-year-old female presented with a hard mass in her left breast. Papanicolaou staining of fine-needle-aspiration cytology specimens showed atypical single cells and cell clusters in a pale green-stained myxoid background. There were three types of cell clusters : carcinomatous, chondromatous, and intermediate clusters in a chondroid matrix.<br>Histologically, the tumor had a chondromatous element at the center and a carcinomatous element in the peripheral region. The tumor demonstrated overt carcinoma with direct transition to a cartilaginous stromal matrix without an intervening spindle cell zone or osteoclastic cells ; based on these findings, we diagnosed the tumor as MPC.<br><b><i>Conclusion</i></b> : It is possible to suspect MPC when both carcinomatous and chondromatous cell clusters appear on the same glass slide with transitional images of these cells. Thus, MPC may be suspected clinically based on its characteristic properties.

    We report herein on a 75-year-old male who presented with melena. Initial upper GI endoscopy, colonoscopy and computed tomography failed to find the bleeder. Capsule endoscopy revealed a polypoid lesion with net-like white line in the ileum, followed by double-balloon endoscopy which revealed a club like polypoid lesion located at the distal ileum. A Barium meal examination revealed a bulbous polypoid filling defect in the ileum. We therefore diagnosed that the lesion was an inverted Meckel's diverticulum. Surgical resection was performed. Pathologic examination indicated inverted Meckel's diverticulum. We propose that capsule endoscopy and double-balloon endoscopy are promising techniques to diagnose an inverted Meckel's diverticulum.

    We report the case of a 56-year-old man with a gastric carcinoid tumor associated with type A gastritis. In December 2010, multiple ulcerative lesions were detected during a barium meal examination. Gastric endoscopy revealed erosive lesions, ulcer scars and multiple small red spots all over the stomach and he was diagnosed with a gastric carcinoid tumor histologically. The serum gastrin level was 1,900 pg/ml. We determined that this gastric carcinoid was associated with type A gastritis and performed laparoscopy assisted distal gastrectomy to decrease the serum gastrin level. The serum gastrin level dropped down to normal range and all carcinoid tumors disappeared.

    <b><i>Background</i></b> : Invasive micropapillary carcinoma (IMPC) accounts for approximately 3% of all breast cancer cases and is rarely reported in male patients. Our report describes the cytological and histological features of IMPC of the male breast.<br><b><i>Case</i></b> : A 56-year-old man presented with a hard mass in his right breast. Fine needle aspiration cytology showed many clusters on a clear background. The clusters were of 2 types : clusters with poor connectivity and cohesive papillary clusters. The latter had smooth surfaces and exhibited an &ldquo;inside-out&rdquo; pattern with the apical cytoplasm toward the periphery of the clusters. Histologically, the lesion showed a few differences in patterns. The major pattern was typical of IMPC separated by a mesh-like fibrovascular stroma. Minor components such as papillotubullar carcinoma, and scirrhous carcinoma were also observed. The major IMPC component occupied over two-thirds of the lesion, and thus we diagnosed the lesion as IMPC.<br><b><i>Conclusion</i></b> : IMPC can be distinguished from other types of carcinomas because the clusters exhibit an inside-out pattern with the apical cytoplasm toward the periphery. It is important to clinically suspect IMPC because of its high malignancy.
