Pancreatic Lymphangioma: A Case Report and Literature Review

We report a case of a 29-year-old woman with a pancreatic lymphangioma who presented clinically as a case of acute pancreatitis. Lymphangiomas are benign tumors of vascular origin with lymphatic differentiation, most commonly found in the head and neck. Pancreatic lymphangiomas are extremely rare, accounting for only 1% of abdominal lymphangiomas, with approximately 60 cases reported in the literature. Although imaging findings are characteristic and can point to the diagnosis, confirmation with fine needle aspiration and histopathologic correlation is necessary. Although these lesions are benign, they can often present a diagnostic dilemma and can be mistaken for other cystic pancreatic lesions, namely, pseudocysts, cysts, cystadenomas, and cystadenocarcinomas.
