[Malignant fibrous histiocytoma of spermatic cord: a case report].

A 52-year-old man presented with a painful, gradually enlarging mass in the left inguinal region. An ultrasound examination demonstrated a lobulated, heterogenous tumor 6.0 x 4.0 x 3.0 cm in diameter, which separated from the left testis and epididymis. Radical inguinal orchiectomy with wide en bloc local resection was performed. Histologic diagnosis was a malignant fibrous histiocytoma (MFH) with a giant cell variant. The patient underwent postoperative regional irradiation and has been alive without metastasis and local recurrence 3 months after the operation. Among the 19 patients with MFH of spermatic cord reported in Japan, only two cases were of giant cell type of MFH including the present case.
