Autoimmune testicular vasculitis.

A 38-year-old man presented for evaluation of new-onset left testicular pain with swelling. Testicular ultrasound revealed multiple intraparenchymal hypoechoic areas in the inferior portion of the left testicle. The patient was treated with a radical inguinal orchiectomy. Pathologic evaluation revealed intratesticular vasculitis, with involvement of medium-sized arteries. This appears to be a rare case of isolated testicular vasculitis, in the absence of any systemic symptoms.
