Fibrous pseudotumor of the tunica vaginalis testis.

The incidence of fibrous pseudotumor of the tunica vaginalis testis is rare. It is a benign, fibroproliferative process with hyalinization and sometimes with focal calcification. In most cases malignancy is suspected although by careful physical examination it may be possible to establish the diagnosis pre-operatively. The best form of therapy is frozen section biopsy of the pseudotumor followed by excision; including if necessary the tunica vaginalis. If the pseudotumor is locally extensive an epididymectomy is sometimes necessary. A study of the literature reveals that because of the rarity of this lesion orchidectomy appears to have been performed in most cases. A case report of a patient with fibrous pseudotumor of the tunica vaginalis testis is presented.
