A unique scrotal extratesticular epidermod cyst attached to the seminal vesicles.

A 46-year-old man was admitted with a scrotal long standing painless mass. The workup included physical examination, alpha-fetoprotein (αFP) and beta-human chorionic gonadotropin (β-hCG) analyses, scrotal ultrasound, magnetic resonance imaging and urethrocystoscopy. Surgical exploration revealed a separate mass between the testes extending superiorly with a thin stalk. It was dissected easily to the anterior aspect of the seminal vesicles and removed from the junction to the seminal vesicles. Pathology reported an epidermoid cyst. To our knowledge this is the first case of a scrotal extratesticular epidermoid cyst attached to the seminal vesicles.
