Epidermal Inclusion Cyst in an Intra-pancreatic Accessory Spleen: a Differential Diagnosis for Pancreatic Cystic Neoplasms and Review of the Literature

摘要

Introduction: The incidence of accessory spleen is approximately 10% in autopsy findings, with the most frequent location being at the tail of the pancreas [1, 2]. Epidermoid cysts arising from ec-topic spleen tissue in the tail of the pancreas are a benign and extremely rare pathology. At present, less than 50 cases were being reported in the English literature. This entity is not well characterized; we aim to shed some light in this rare entity with a brief literature review and our experience in two cases.
