Fibrous pseudotumors of tunica albuginea, tunica vaginalis and epididymis: report of two cases.

We describe two rare cases of fibrous pseudotumor of the paratesticular region. In the first case, five nodules arising from the tunica albuginea of right testicle causing scrotal, enlargement raising after urinary tract infection were seen. In the second case, multiple nodules arising tunica albuginea, tunica vaginalis and epididymis raising after left varicocelectomy operation were observed. The histology showed a paucicellular fibroblastic proliferation of cells within a hyalinized collagenous fibrous stroma containing numerous thin-walled blood vessels accompanied by lymphocytes and plasma cells in tumor tissues in both cases. Tumors in both cases were successfully resected. After operation, both patients had an uneventful recovery without any complications.
