Fibrous pseudotumor of tunica vaginalis and epididymis.

Paratesticular fibrous pseudotumors are rare, and less than 10% of them affect the epididymis. We report a case of testicular trauma that progressed to a painless palpable tumor in the right hemiscrotum with increased local volume. Orchiectomy followed by anatomic-pathologic examination revealed a paratesticular fibrous pseudotumor. The best treatment is scrotal exploration and frozen biopsy. On confirmation of the diagnosis, only the tumor and the tunica vaginalis are resected. Should the benign nature not be possible to determine, orchiectomy is the procedure of choice. We also reviewed published reports for this possibility in the differential diagnosis of testicular masses.
