Marked increases of aminotransferase levels after cresol ingestion

A 26-year-old woman developed marked increases in levels of aminotransferases about 24 hours after ingestion of 70 mL of 50% cresol. Responding to supportive measures, the patient recovered without any significant complications. Cresol and/or its metabolite may have caused transient hepato-cellular injury in this patient. In cresol poisoning, hepato-cellular injury can manifest even after a 24-hour asymptomatic period.
