Mucinous cystadenocarcinoma of the pancreas

Definition

A rare, epithelial tumor of the pancreas characterized, histologically, by columnar, mucin-producing epithelium associated with ovarian-type subepithelial stroma, which does not communicate with the pancreatic ductal system, most frequently localized to the body or tail of the pancreas. Clinically, small tumors (<3 cm) are usually asymptomatic, while large tumors typically present obstructive jaundice, a palpable abdominal mass, and may associate portal hypertension, hemobilia and diabetes mellitus.
