Nicolau syndrome is a rare complication caused by the intramuscular, intraarticular or subcutaneous administration of several drugs. We report the case of a 30-year-old patient, who after the intramuscular injection of the third dose of benzathine penicillin developed an equimotic plaque with violet peripheral reticulation at the aplication site accompanied by neurovascular effects.
