A case of solid and cystic tumor of the pancreas

Abstract

We report a rare case of a solid and cystic tumor of the pancreas.
The patient is a 13-year-old girl with a tumor in the head of the pancreas. Based on gross observations and immunocytochemical examinations, the tumor was diagnosed as a solid and cystic tumor. Cytological examinations by the crush method immediately after the operation showed that the tumor cells were columnar with a wide cyanophilic cytoplasmas and biased nuclear. Dysplasia was not observed. The majority had like a columnar shaped with an unclear cell boundary, but a few cells were like an oval or polyhedral with a clear cell boundary. Aggregations of coarse cyanophilic granules were also observed. These granules reacted positively to PAS, α₁-antitrypsin, and pancreatic-amylase. Neurospecificenolase reacts showed positive to the cytoplasm of the cells shaped like oval or polyhedral. It seems important to pas special attention to coarse cyanophilic granules stained as well as to the cell shaped like columnar or oval when diagnosing solid and cystic tumor of the pancreas immunocytochemically.
