Malignant fibrous histiocytoma of the right spermatic cord: A case report

The patient was a 47-year-old male, who visited Hidaka Hospital with a chief complaint of swelling in the right inguinal region and the scrotum. With a diagnosis of a right spermatic cord tumor, right high orchiectomy was performed. Since an inflammatory type of malignant fibrous histiocytoma (MFH) was diagnosed from histopathological findings, chemotherapy and radiation therapy were performed as postoperative treatment. Malignant fibrous histiocytoma with the primary focus of the spermatic cords is a rare disease. To our knowledge, this is the 20th case of MFH of the spermatic cord in Japan (the 42nd in the world) and it is the second case of inflammatory type of MFH in Japan.
