A thinner is an industrial solvent that is composed of some aromatic hydrocarbons. Acute or chronic intoxication is frequently seen among industrial workers who inhale solvent vapor and in teenager’s abuse using thinner. Suicidal injection use of a thinner is very rare. An 18-year-old young boy presented to our department with pain and swelling in his left arm. His complaints had started three days after he attempted suicide with the injection of a paint thinner. High fever, extensive swelling, and local warming in the left arm from the shoulder to the over hand was observed on admission. His leukocyte count was 26820/mm3 and CRP level was 194mg/L. Because his clinical picture mimicked severe soft tissue infection, antibiotic treatment was initiated. Abscess formation developed at the injection site on day eight, and surgical drainage was performed. Upon clinical and laboratory improvement, the patient was discharged on the 16th day of therapy.
