A 62-year-old woman presented with abdominal pain and dyspepsia. CT revealed a multicystic mass in the tail of the pancreas; the other organs were normal and there was no lymphadenopathy. The pancreatic mass, 6.5 x 2.5 x 2.5 cm, was well demarcated, composed of multiple small cysts, and contained a central stellate scar. The neoplastic cells were found to have PAS positive, diastase digestible, cytoplasmic material. The spleen and lymph nodes were unremarkable.
