Abstract

Among extramedullary manifestations of multiple myeloma, testicular localization is exceptional. A scrotal mass in this context poses diagnostic and therapeutic challenges given the aesthetic, psychological and reproductive impact of surgery. Authors report a case of testicular plasmocytoma seven years after remission from multiple myeloma. The treatment consisted of left inguinal orchidectomy. Diagnosis needed the recourse to immunohistochemistry. Diagnostic modalities, therapeutic options and evolutive eventualities will be discussed. Extra-medullar localization is exceptionally reported in extramedullary multiple melanoma. Management depends on the concomitant or distant character of hemopathy diagnosis and the disease evolutive history.

Keywords: Multiple myeloma; Orchiectomy; Recurrence; Testicular neoplasms.
