Mucinous cystic neoplasm with ovarian like stroma in male patient: a case report

Abstract

Mucinous cystic neoplasm (MCN) is almost always arising in female. There are a limited number of articles reported about MCN in male patients. The diagnosis is based on cystic lesion of pancreas, simple lining epithelium, and typical ovarian stroma. This is the first case report of MCN of the pancreas in a male patient in the archive. The mass was at the tail of the pancreas. No communication between the bile duct and the mass was present both in imaging study and pathologic study. Mucosal epithelium demonstrated low grade dysplasia but no malignant transformation. Ovarian-like stroma was highlighted by immunohistochemical studies. Resection was complete. MCN with no invasive malignant part is usually benign, but there is uncertain long-term outcome in male patients.
