Giant fibrolipoma of the spermatic cord.
Fibrolipoma of the spermatic cord is extremely rare. A case of giant fibrolipoma of the right spermatic cord is reported here. A 68-year-old man noticed a mass in the right inguinal region, and was admitted to Shizuoka City Shimizu Hospital. Tumorectomy and right orchiectomy were performed. Grossly, the tumor was a well-defined, yellowish white, solid, firm tumor measuring 13 x 10 x 9 cm. The tumor had a thin capsule. The tumor was attached to the right spermatic cord, and was remote from the right testis and epididymis. Microscopically, the tumor was composed of mature adipose tissue (40% in area) and collagenous fibrous tissue (60% in area). No lipoblasts were recognized, and on immunohistochemistry the tumor was negative for MDM2 and CDK4. Neither smooth muscle nor vascular proliferation was recognized. The tumor was diagnosed as giant fibrolipoma of the right spermatic cord. To the best of the author's knowledge, only two cases of fibrolipoma in the spermatic cord, scrotum, and testis have been reported in the English-language literature.
