Surgery is recommended for all types of pancreatic intraductal papillary mucinous tumors

Intraductal papillary mucinous tumors of the pancreas

Intraductal papillary mucinous tumors (IPMTs) are benign and malignant lesions that arise from the epithelial lining of main pancreatic duct and/or branch pancreatic ducts, with excessive mucin production (especially hyperplastic/adenomatous variety). Based on the degree of cytoarchitectural atypia on microscopic examination, IPMTs are classified as benign, borderline, carcinoma in situ and inv...

Intraductal papillary mucinous neoplasm.

A 75-year-old male with a history of dyslipidemia, no alcohol abuse, acute pericarditis and two pancreatitis episodes 16 and 3 years ago, consulted due to a new pancreatitis episode (amylase 536 IU/l). Abdominal CT and MRI showed irregular, rosary-like dilatation of the duct of Wirsung in the body and tail (Fig. 1). In the pancreatic body-tail, echoendoscopy revealed a 15-mm duct of Wirsung wit...

Preoperative predictors of malignancy in pancreatic intraductal papillary mucinous neoplasms.

HYPOTHESIS Malignant intraductal papillary mucinous neoplasms (IPMNs) can be predicted before surgery. DESIGN Retrospective review of a prospectively collected database. SETTING Academic, urban, tertiary care hospital. PATIENTS Sixty-four consecutive patients with a pathological diagnosis of IPMN. INTERVENTIONS All 64 patients underwent surgical intervention for IPMN between December 8,...

Diffuse replacement of pancreatic parenchyma by intraductal papillary mucinous neoplasm.

A 63-year-old insulin-dependent diabetic womanpresented to ourmultidisciplinary group for evaluation and management of multifocal cystic lesions of the pancreas found incidentally by computed tomography during an evaluation of diverticulitis. Initial assessment included endoscopic ultrasound (EUS) with fine-needle aspiration (FNA) by curved linear array echoendoscope. Near-total replacement of ...
