Primary Pancreatic Mature T-Cell Lymphoma as a Cause of Obstructive Jaundice: A Case Report and Review of the Literature.

Primary pancreatic lymphoma (PPL) is an extremely rare type of non-Hodgkin's lymphoma (NHL). It accounts for 0.1% of all lymphomas and less than 1% of pancreatic tumors. Within this subtype, T-cell lymphomas only account for up to 6.7% of pancreatic lymphomas. In this study, we present the case of a 78-year-old Hispanic man who presented with obstructive jaundice associated with a mass within the head of the pancreas; pathologic analysis of the tumor revealed a mature T-cell lymphoma, not otherwise specified (NOS).
