Abstract

Context Pancreatic cystic lesions are increasingly recognized and comprise different pathological entities. The management of these lesions is challenging, because of inadequate preoperative histological diagnosis. Among this family of lesions, mature cystic teratomas are an extremely rare finding. Case report We present the case of a 61-year-old man with a mature cystic teratoma of the pancreas’ uncinate process, incidentally discovered at diagnostic imaging. Conclusions This case highlights the difficulty to obtain a preoperative diagnosis of this pathological entity and the need of increased awareness about mature cystic teratoma when examining a pancreatic cystic lesion.
