Primary testicular diffuse large B-cell lymphoma in young patient: an uncommon presentation

Abstract

Primary testicular lymphoma (PTL) is a rare form of extranodal lymphoma, this neoplasm is the most common malignant tumor of the testis in the elderly age, and the majority of cases are histologically diffuse large B-cell lymphoma (DLBCL), accounting for 80% to 98% of non-hodgkin lymphoma. Patients with primary testicular DLBCL show a continuously high risk of recurrence with no plateau in the survival curves and a tendency to involve other extranodal sites, especially the central nervous system and the contralateral testis. We report a rare and uncommon presentation of a primary testicular diffuse B cell lymphoma in young patient.
