Case ReportA previously healthy 30-year-old male began work as a degreaser. The solvent used in the degreasing operation was trichloroethylene. Over the next month he experienced symptoms of weakness, dizziness, decreased appetite, nausea, abdominal pain, diarrhea, fever, chills, dry skin, red rash with bumps, peeling face, and itching. At that time he had marked liver enzyme elevation without evidence of cholestasis. CBC was remarkable for a significant number of atypical lymphocytes. Two weeks later his liver enzymes showed a marked reduction in ALT from a peak of 1250 IU to 717 IU. Tests for Hepatitis A, B, and C, CMV, HIV1 were all negative. The night following his first day back at work he had a recurrence of a red, diffuse rash without any consumption of alcohol. The rash caused tremendous itching. Over the next few days off work the rash continued and peeled. Physical examination one week after re-exposure was remarkable for diffuse, erythematous rash; some peeling skin and pitting edema to the knees. ALT was 517 IU/L. White blood cell count was 10,100/mm3 with 27% eosinophilia.ConclusionThis patient had possibly experienced sensitization to trichloroethylene, or more likely, to one of its metabolites. Similar symptoms attributed to trichloroethylene have been reported in only a few other patients. Patch testing with trichloroethylene and its metabolites may better clarify a causal relationship in future patients. If an immune mechanism is involved it may be similar to one postulated for halothane induced hepatitis.
