Inflammatory myofibroblastic tumor of the epididymis: case report and review of the literature.

The inflammatory myofibroblastic tumor (IMT) is a rare benign tumor, known by several names and found in several locations throughout the body, including the lungs and genitourinary system (mostly the bladder). We report a case of a paratesticular IMT in a 17-year-old boy. Although the initial clinical diagnosis was rhabdomyosarcoma, the histopathologic examination revealed it to be an IMT. The preoperative diagnosis of a scrotal mass should differentiate between benign and malignant tumors. A definitive diagnosis of a scrotal mass should be established by surgical exploration and resection. It is important to counsel patients with scrotal masses regarding the possibility of orchiectomy, even in the case of a benign tumor such as IMT.
