An Unusual Presentation of Extra-Nodal Pelvic Diffuse Large B-Cell Lymphoma

Abstract

An 80 years old man with a history of Rheumatoid Arthritis and Charcot-Marie-Tooth disease presented with urinary retention, constipation, weight loss and anorexia. CT imaging showed a large presacral mass, with tissue biopsy identifying diffuse large B cell lymphoma. PET imaging did not identify any lymphadenopathy. This case illustrates a rare pelvic manifestation of a common haematological malignancy.
