MUC1 glycoprotein is overexpressed and its intracellular localization altered during breast carcinoma tumorigenesis. The present study aimed to clarify the relationship of cytoplasmic localization of MUC1 with the breast cancer subtype and the correlation of 10 molecules associated with cell polarity in breast cancer subtypes. We immunostained 131(More)
We report the rare case of an elderly patient with an advanced gastric cancer arising from an upside-down stomach through a paraesophageal hiatal hernia (PEH). An 82-year-old man presented with appetite loss and anemia. Upper gastrointestinal endoscopy revealed a type 1 tumor located in the middle body of the stomach. An upper gastrointestinal series and(More)
Peptide YY (PYY) is a peptide hormone secreted from L cells in the intestine in response to food intake that regulates appetite and gastrointestinal function. PYY is also produced in the pancreatic islets. The vitamin D receptor (VDR) is a nuclear receptor for the active form of vitamin D3 that regulates numerous physiological processes. VDR is expressed in(More)

Killian-Jamieson diverticulum is a rare hypopharyngeal diverticulum, less commonly encountered compared with Zenker's diverticulum. These hypopharyngeal diverticula that cause dysphagia often mimic a thyroid tumor incidentally detected on neck ultrasonography. However, to our knowledge, Killian-Jamieson diverticula complicated by a thyroid tumor have not(More)
Pancreatic fistula is the most serious postoperative complication after pancreaticoduodenectomy, and it leads to intra-abdominal abscess, sepsis, hemorrhage and high mortality. To prevent pancreatic fistula, wrapping of skeletonized vessels and the anastomotic site of the pancreaticoenterostomy using the round ligament, greater omentum, or both has been(More)
We report a case of multiple gastric carcinomas associated with Potter type III cystic disease of the liver, mesenterium and kidney. A 65-year-old man with chronic renal failure due to polycystic kidneys and under hemodialysis treatment 3 times a week for 2 years was admitted to our hospital because of anemia. He stated that his sister had suffered from(More)
A 69-year-old female visited our department with a diagnosis of rectosigmoid cancer and multiple hepatic metastases (stage IV). Abdominal CT revealed multiple metastatic lesions in the bilateral lobes of the liver. The primary lesion was considered to be resectable, and high anterior resection of the rectum was performed. After the operation, 6 courses of(More)
