A 51 year-old male was admitted to our hospital with chief complaints of fever, dry cough and dyspnea. Chest X-ray films and his history of taking Chinese medicine for liver dysfunction were suggestive of drug-induced pneumonitis. ⋯ In vivo challenge test for Sho-saiko-to was positive. The LST with BALF-lymphocytes proved to be very useful in making a diagnosis of drug-induced pneumonitis.
