Pancreatoblastoma in an adult: case report and review of the literature.

A 50-year-old man presented with progressive gastrointestinal symptoms. An abdominal computed tomography scan demonstrated a 12 x 12-cm pancreatic mass involving the greater curvature of the stomach and multiple hypervascular hepatic metastases. An initial fine needle aspiration of the pancreatic mass was nondiagnostic, and a subsequent fine needle aspiration of a liver mass was read as metastatic acinar cell carcinoma.
