Abstract

Mucinous cystic neoplasms (MCNs) of the pancreas in male patients are very rare. Though few cases of MCNs in male patients have been reported, it is difficult to reveal them preoperatively. The first patient was a 50-year-old man and was incidentally found to have a cystic mass of 51 mm in the tail of the pancreas. We performed a distal pancreatectomy. The second patient was a 73-year-old man, incidentally found to have a cystic mass of 25 mm in diameter in the tail of the pancreas and a carcinoma of the bile duct. We performed a subtotal stomachpreserving pancreaticoduodenectomy and distal pancreatectomy. In both cases, the cystic lesion was diagnosed pathologically as MCNs. Since MCNs have the risk of malignancy, a resection is recommended. Cases of MCNs in male patients exhibit features that are similar to MCNs in women. We should recognize that MCNs of the pancreas in male patients exists.
