Solid Pseudopapillary Epithelial Neoplasm of Pancreas, Mimicking a Hematoma in a Young Boy.

Solid pseudopapillary pancreatic neoplasm (SPEN), also known as Frantz's tumor, is an uncommon pancreatic tumor typically affecting young and adolescent females and characterized by low-grade malignancy. It is rare in men and children. This case report details the incidental diagnosis of a solid pseudoepithelial tumor within the pancreas of an early adolescent boy who presented with abdominal pain following blunt abdominal trauma. The mass was initially misinterpreted as a hematoma given the history of trauma. This case underscores the significance of precise diagnosis, noting the course of events and the prognosis of SPEN.
