Plasmocytoma of the Urethra

Case History and Findings: A 35-year-old male patient presented with a 1-year history of hesitancy in voiding. An urethrogram revealed urethral stricture, therefore an urethrotomy with biopsies was performed. Histologic results suggested the diagnosis of extramedullary mature plasmocytoma. Treatment and Outcome: After external beam radiotherapy with a total dose of 45 Gy the patient is disease-free without any therapy-related late effects after a follow-up of 36 months. Conclusion: Primary localization of extramedullar plasmocytomas in the genitourinary tract is very rare. This case report discusses a case of a male patient suffering from plasmocytoma of the urethra, who could be treated successfully by primary external beam radiotherapy.
