The purpose of this study was to investigate the actual management of mucinous cystic neoplasm (MCN) of the pancreas. A systematic review was performed in December 2009 by consulting PubMed MEDLINE for publications and matching the key words "pancreatic mucinous cystic neoplasm", "pancreatic mucinous cystic tumor", "pancreatic mucinous cystic mass", "pancreatic cyst" and "pancreatic cystic neop...

S19 ENDOSCOPIC ULTRASOUND / VOLUME 6 / SUPPLEMENT 1 / AUGUST 2017 2.7 ± 1.7 cm. Most patients were asymptomatic. The type of cystic lesions was intraductal papillary mucinous neoplasm (IPMN; n = 35), serous cystadenoma (n = 18), mucinous cystic neoplasm (MCN; n = 12), solid pseudopapillary epithelial neoplasm (SPEN; n = 9), cystic degeneration of other tumors (n = 4), simple cyst (n = 4), infec...

Tumors of the pancreas that contain substantial cystic components include mainly mucinous cystic neoplasm, intraductal papillary mucinous neoplasm, solid pseudopapillary tumor, and cystadenomas (which encompass microcystic, macrocystic/oligocystic, and rare solid serous adenomas). Microcystic adenoma of the pancreas is a tumor that is benign in nature. Malignant transformation in the tumor with...

CONTEXT We herein present a rare case of a mucinous cystic neoplasm of the pancreas producing CA 19-9 and the clinical implications are discussed. CASE REPORT A 35-year-old woman with no history of abdominal surgery presented at Saisei Kai Sendai Hospital with an upper abdominal distention. Abdominal CT showed a large lobulated cystic tumor at the pancreatic tail. No distant metastases were i...

Mucin Hypersecreting Intraductal Papillary Neoplasm is a rare neoplasm that arises from ductal epithelial cells. This entity is distinct from the more commonly known Mucinous Cystadenoma or Mucinous Cystadenocarcinoma. Despite this distinction, it has been erroneously categorized with these more common cystic neoplasms. Characteristic clinical presentation, radiographic, and endoscopic findings...

We report two cases of cystic neoplasm of the liver with mucinous epithelium in which both ovarian-like stroma and bile duct communication were absent. The first case was a 41-year-old woman. She underwent right trisegmentectomy due to a multilocular cystic lesion, 15 cm in diameter, with papillary nodular components in the medial segment and right lobe. Histologically, arborizing papillae were...

CONTEXT Cystic tumors of the pancreas have been diagnosed with increasing frequency. Intraductal oncocytic papillary neoplasm is a rare type of cystic pancreatic tumor. Intraductal oncocytic papillary neoplasm is considered a distinct entity with the potential of developing into invasive carcinoma and it should be differentiated from other cystic tumors of the pancreas, including mucinous cysti...
