The erect penis had inadvertently collided with his partner’s perineum. Heheard a snap, noticed a rush of blood from the meatus, had immediate detumescence, and had severe pain. The penile“fracture” refers to a tear in the tunica albuginea, the watertight fibrous outer sheath of the corpora caver-nosa that isresponsible for maintaining the structural integrity of an erection. Disruption of the tunica results in a loss of bloodoutside the corpora, causing a hematoma. The classic eggplant deformity (swelling, discoloration, and deviation awayfrom the defect in the tunica) can be seen. If the fracture involves the urethra, blood will extravasate through theurethra.
