Epithelial inclusion cysts in an intrapancreatic accessory spleen

Abstract

A 38 year old male underwent distal pancreatectomy for benign cystic pancreatic tumor. The pancreas tail contained a 2.3 x 2.1 cm accessory spleen associated with multiple epithelial inclusion cysts. The cysts were of varying sizes (max: 1.4 cm), lined by non-keratinizing squamous epithelium with a few mucin-producing cells, and filled with serous material. This is the fifth reported case of so-called 'epidermoid' cysts in the intrapancreatic accessory spleen.
