title: Scorpion sting on the penis.
abstract: A 58-year-old man was stung on the penis by a scorpion of the species Tityus serrulatus. The patient felt a severe sharp local pain that did not improve until he presented to the hospital 12 hours later. Block of the dorsal nerves of the penis with 1% lidocaine led to immediate relief of the pain. The aim of treatment of a Tityus scorpion sting on the penis, without systemic manifestations, should be concentrated on relief of the pain. Local or regional block with a local anesthetic is the treatment of choice. The use of the specific antivenom is recommended only for cases of systemic manifestations, particularly in children.
