The entire pathogenesis of this syndrome is unknown, but it has been associated with vascular injury, arterial thrombosis, reflex spasm of the arteries, vascular occlusion due to microemboli, and inflammation. Clinical case: 32-year-old male. After an intramuscular injection of benzathine penicillin, the patient presented severe pain in the injection area accompanied by erythematous lesions at the level of the abdomen, scrotum, and right lower limb. In addition to that, the patient presented pain, paresthesia, and mottled paleness erythema (livedo).

Conclusion: Nicolau Syndrome, is an iatrogenic condition that is produced by injection of multiple drugs. It can produce different symptoms and signs from neurological injury, necrosis in the irrigation area of affected vessels and acute ischemia. rt-PA management in this case was effective in treating ischemia.
