Abstract

A case of haemangiopericytoma of right spermatic cord is reported. A 50-year old male presented with a month-lasting painless swelling of right scrotum. Ultrasonography revealed a soft tissue mass in right spermatic cord, which was about 3.5cm in diameter. Right high inguinal orchiectomy was performed. The tumor was solid, smooth surfaced and well circumscribed. Histologically, the tumor had many capillary vessels and short spindle calls around the vessels. On the silver impregnation, argyrophil fibers surrounded the tumor cells. Immunohistologically, tumor cells were positive for CD34 antigen and negative for facter VIII antigen. The mitotic rate was 2per high-power field. Accordingly, this tumor was diagnosed as benign haemangiopericytoma. The patient is doing well without any sign of recurrence, as of 30 months post-operatively.
Haemangiopericytoma is a rare neoplasm of pericyte origin. It commonly occurs in retroperitoneum and lower extremities. To our knowledge, only two cases of malignant haemangiopericytoma of the spermatic cord was reported, and this case is the first benign case of the spermatic cord.
