Abstract:

Only a few cases of inflammatory myofibroblastic tumor (IMT) occurring in epididymis were reported, and all of them were single tumors. We reported a case of multiple IMT of epididymis. The patient found a mass in the right scrotum for a year, and the mass increased progressively. Ultrasonography showed multiple solid nodules in the right scrotum. Right scrotal exploration and resection of mass were performed. Multiple round pleniform masses were found in the right epididymis during the operation. The pathology of the masses was IMT. No recurrence of the masses was found after 6 months of postoperative follow-up. By reviewing the literature, we supposed that IMT of the epididymis had similar clinical symptoms to other masses occurring in the epididymis. It was generally difficult to clarify the IMT before surgery. The tumor would grow progressively and had low malignant potential, so it was recommended to remove the tumor surgically. The patients did not need other special treatment after surgery, because the IMT would not recur generally. However, the regular review was required.
