Although cystic tumors of the pancreas are relatively rare, they constitute an increasingly important category. Advances in imaging and interventional techniques and the sharp drop in the mortality rate of pancreatic surgery have rendered pancreatic biopsies and resections commonplace specimens. Consequently, in the past two decades, the nature of many cystic tumors in this organ has been bette...

Mucinous cystadenocarcinoma (MCA) in the breast is a rare neoplasm. There have been 13 cases of primary breast MCA reported. The MCA presents as a large, partially cystic mass in postmenopausal woman with a good prognosis. The microscopic findings resemble those of ovarian, pancreatic, or appendiceal MCA. The aspiration findings showed mucin-containing cell clusters in the background of mucin a...

BACKGROUND Pancreas divisum, the most common congenital anomaly of the pancreas, is caused by failure of the fusion of the ventral and dorsal pancreatic duct systems during embryological development. Although various pancreatic tumors can occur in patients with pancreas divisum, intraductal papillary mucinous neoplasm is rare. CASE PRESENTATION A 77-year-old woman was referred to our hospital...

Intraepithelial neoplasias are preinvasive neoplastic lesions found throughout in the digestive system, and when such lesions are discovered in the gallbladder, they are referred to as intracystic papillary neoplasm (ICPN). In the gallbladder, mucinous adenocarcinoma is a rare histologic phenotype, and adenocarcinomas involving Rokitansky-Aschoff (RA) sinuses are uncommon, which were indeed fou...

Mucinous cystadenocarcinoma is an extremely rare variant of primary breast tumor which is histologically similar to mucinous cystadenocarcinoma of the ovary and pancreas. Herein we report a case of a 63 years old woman diagnosed with diverse histological types of non-synchronous rare primary breast tumors, a medullary carcinoma of the right breast and a mucinous cystadenocarcinoma of the left b...

Mixed mucinous cystadenoma with serous cystadenoma of the pancreas is rare. There have been only two previous case reports in the English-language literature. We present a case of a 46-year-old woman who was diagnosed with mixed mucinous cystadenoma with serous cystadenoma of the pancreas. Computed tomography and magnetic resonance imaging showed a cystic neoplasm in the dorsal/proximal body of...

Urachal carcinoma is an uncommon neoplasm. Benign urachal tumours are extremely rare. All urachal mucinous tumours, regardless of tumour type, have the potential to behave in an aggressive clinical manner that includes the development of pseudomyxoma peritonei. We report a 58-year-old man who presented with lower abdominal pain. Ultrasound and CT imaging defined a large lobulated cystic mass su...
