Penile dorsal vein rupture is a rare condition that affects the vascular network of the penis. It is often misdiagnosed as a penile fracture. Diagnosis can be facilitated by ultrasound of the penis coupled with Doppler or magnetic resonance imaging. Treatment options include conservative or surgical approaches. This case report presents an adult patient who presented to the emergency department with a suspected penile fracture six hours after vigorous sexual intercourse. Although a fracture of the corpora cavernosa was ruled out, an intraoperative discovery revealed a rupture of the dorsal vein of the penis. The purpose of this article is to report an uncommon case of rupture of the superficial dorsal vein of the penis.
