Seminal vesicles tumor: Rare localization of lymphoma. A case report.

A case affected by a seminal vesicles secondary tumor to diffuse large B-cell lymphoma is reported. Seminal vesicles neoplasms are scarce, and they can be classified into primary or secondary. The most common case is their involvement by extension of adjacent tumors, which are clinically nonspecific. In the case presented herein, the patient complained of oliguria, constipation and perineal pain, where imaging methods revealed the growth of both seminal vesicles. Pathological examination revealed infiltration of seminal vesicles by diffuse large B-cell lymphoma. In view of this clinical event, we briefly reviewed literature related to the involvement of seminal vesicles tumor.
