Abstract

Background: Several cases of chloroform-induced hepatotoxicity have been reported worldwide, but only 2 cases have been reported in Korea. We encountered a case of toxic hepatitis due to chloroform exposure in February 2022 and report the diagnosis process and clinical findings. Case presentation: A 38-year-old employee in charge of the coating after washing (degreasing) at an automotive parts manufacturer complained of jaundice and was diagnosed with acute toxic hepatitis. After the initial diagnosis, he continued to work, his symptoms worsened, and he was hospitalized for 8 days. Liver ultrasonography (elastography) revealed acute hepatitis. The washing agent contained chloroform, which was not listed on the materials safety data sheet, and the concentrations of chloroform in the workplace were up to 4.7 times the time-weighted average. Conclusions: This patient showed typical toxic hepatitis with chloroform; further follow-up studies are required. Both employers and workers should be aware of information on toxic substances and take precautions to avoid exposure.
