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 r
elief 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 recomme
nded only for cases of systemic manifestations, particularly in childr
en.
