Osler Weber Rendu Syndrome

A 71-year-old man arrived at the urology department complaining of gradual, painless, right testicular enlargement over the last month. On physical examination, the right testicle was enlarged and firm without discrete mass. A vascular lesion was observed on the upper lip. Past medical history was notable for a cerebrovascular accident due to an arteriovenous malformation 23 years prior. A color Doppler ultrasound of the testis confirmed a solid infiltrating lesion in the right testicle (Fig. 1). Serum markers were negative (alpha-fetoprotein, human chorionic gonadotropin, and lactate dehydrogenase). Given the testicular mass, an abdominal and pelvic computed tomography (CT) scan was performed. Although no paracaval adenopathies were found, evidence of bleeding from the right seminal vesicle was detected (Fig. 2). Consequently, a radical right inguinal orchiectomy was performed (Fig. 3). The histopathological examination disclosed a 5-cm cavernous hemangioma of the testis. ©Elsevier
