Arteriovenous malformation of scrotum: a case report.

Arteriovenous malformations of the scrotum are rare. We report a case of arteriovenous malformation involving the scrotal vessels. The patient presented with painful scrotal swelling, which was mainly in the skin and the Dartos layers. Vascular lesions of the scrotum are rare. By far the most common condition is varicocele. Our patient was examined by 2 other urologists before us and no one made the diagnosis of arteriovenous malformation on clinical examination. Diagnosis was made by auscultation with the Doppler stethoscope. We suggest that the possibility of a scrotal arteriovenous malformation and hemangiomas should be entertained in patients with unilateral scrotal swelling.
