Benign fibrous pseudotumor of tunica vaginalis testis.

We discuss the rare benign paratesticular mass identified as fibrous pseudotumor. We performed a published data search to review the etiology, incidence, gross and microscopic examinations, and pathologic diagnostic considerations. Fibrous pseudotumor is a rare, benign lesion. Histologic examinations, as well as concerted efforts between the pathologist and surgeon, are necessary for appropriate diagnosis and treatment.
