Background: Dichloromethane (a chlorinated hydrocarbon) is normally used as a solvent. Dichloromethane poisoning has been reported from occupational exposure and the common routes of dichloromethane poisoning are ingestion and inhalation. Case presentation: We described a case of 51-year-old man who received subcutaneous injection of dichloromethane and presented with local wound necrosis at his forearm, but carboxyhemoglobin levels were normal. Discussion: The corrosive property of dichloromethane result in venous thrombosis formation at his wound that might prevent systemic absorption of dichloromethane leads to reduced hepatic converted dichloromethane to the carbon monoxide. Conclusion: Symptomatic treatment and monitoring of CO production remain the mainstay in the treatment of patients with subcutaneous injection of dichloromethane.
