Abstract

A 70-year-old woman complained of upper abdominal pain, and thorough medical examination (including CT, MRI, EUS) revealed a 2.5-cm round cystic lesion in the pancreas tail. It had a septal wall and mural nodule-like structure without a capsule. Retention of contrast agent in the lesion was observed by ERCP. However, as exclusion of mucinous cystic neoplasm was not possible, the tail of the pancreas and spleen were excised. The lesion was a multilocular cyst with a fairly thick septum that contained concentrated mucin. The main pancreatic duct passed through the lesion and there was no dilatation of the pancreatic duct. The cystic epithelial cells were monolayer with mild atypia. Fusiform-shaped cells were densely present in the stroma of the septum and the edge of the lesion. These cells were estrogen receptor/progesterone receptor positive, and were accordingly considered as an ovary-like stroma. The lesion was diagnosed as mucinous cystadenoma, possibly at early stage based on its small size, the lack of a capsule, and the distribution of ovary-like stroma.<br>
