BACKGROUND Early gastric cancers with duodenal invasion are rare, and no previous case of multiple early gastric cancer, one invading the duodenal bulb, has been reported. CASE PRESENTATION A 79-year-old woman was investigated for upper abdominal discomfort. Endoscopic examination revealed an irregular nodulated lesion in the antrum area, and a reddish aggregated-type semi-circumferential nod...
Intraductal papillary mucinous tumor of bile ducts radiologic and pathologic features: a case report
We report a case of a 67-year-old Caucasian man with right upper quadrant abdominal pain. He underwent radiologic investigations that revealed a solid, focal mass, at the V hepatic segment. Because a definitive diagnosis, based on imaging appearance of the lesion, was impossible in our case, we performed a hystopathological investigation but the biopsies were inconclusive. So, the definitive di...
Biliary cystadenoma is reported in an 8-year-old female Caucasian dog diagnosed by gross and microscopic examination. The lesion observed during postmortem examination on the liver was a 3×2cm cream-coloured raised nodule that extended into parenchyma another 2×4cm cyst filled with mucoid fluid. Histopathology showed multiloculated cysts lined columnar occasionally flattened epithelial cells, p...
There has been an increase in the number of reported cases of biliary neoplasm of the hepatobiliary system characterized by markedly dilated and multifocal papillary epithelial lesions of the bile ducts or cystic biliary lesions with or without mucin secretion, and mucinous lesions or tumors, possibly due to recent advances in radiological diagnosis. This lesion of the bile duct is believed to ...
Ischemic rupture of the anterolateral papillary muscle is uncommon due to its dual blood supply. It usually follows an ischemic event involving branches of the left circumflex or left anterior descending arteries. We present a case of a patient admitted with an acute inferior wall myocardial infarction and an isolated distal right coronary artery occlusion. Acute mitral regurgitation with ruptu...
Aggressive digital papillary adenocarcinoma is a rare eccrine sweat gland malignancy that is frequently misdiagnosed at initial presentation. Histologically, this tumor is similar in appearance to many adenocarcinomas and as such may be diagnosed as a metastatic lesion. We present the case of a patient with digital papillary adenocarcinoma, which was initially diagnosed as a felon. No consensus...
OBJECTIVE The purpose of our study was to determine useful CT criteria for differentiating serous oligocystic adenomas of the pancreas from other similarly presenting neoplasms, such as mucinous cystadenoma and intraductal papillary mucinous tumor of the branch duct type. MATERIALS AND METHODS Forty-one patients with histologically confirmed macrocystic neoplasms of the pancreas were enrolled...
The activation of RET protooncogene, through chromosomal translocation, is unique to papillary thyroid carcinomas. Rearrangement of the RET kinase domain to 3 partner genes has been described, of which the RET/PTC1 is the most common. To investigate the frequency of RET rearrangement in Chinese papillary thyroid carcinomas, we have performed RT-PCR to amplify specific RET/PTC transcripts. Among...
Digital papillary adenocarcinoma (DPAca) is an aggressive lesion with high metastatic potential, which is easily misdiagnosed. We present a 55-year-old male with a cystic lesion on his right thumb. Above all else, lesions of the digits should be sent for histopathology routinely, regardless of their history or appearance.
Background The objective of this study was to assess the impact of right ventricular (RV) trabeculae and papillary muscles on measured volumes and function assessed by cardiovascular magnetic resonance (CMR) using a novel semiautomatic segmentation algorithm in patients with right heart lesion of the congenital heart diseases. The new algorithm was based on the signal intensity distribution of ...
