Giant Cystic Pancreatic Lymphangioma with Mediastinal Extension: A Case Report and Review of the Literature

Lymphangioma is an infrequent benign tumour that is formed usually from a congenital malformation of the lymphatic ducts causing lymphangiectasis. The abdominal location represents 1-5%, with dominance in the mesentery and retroperitoneum, however, the pancreatic location is very rare having described less than 100 cases published worldwide. The clinical symptoms of the lymphangiomas are non-specific and depend of the tumour’s size and location. Here we present a clinical case of a pancreatic lymphangioma with mediastinal extension who was treated with a complete resection and this case shows that the diagnosis of cystic pancreatic lymphangioma must be taken as a differential diagnosis of pancreatic cystic lesions.
