A 64-year-old male who had undergone laparoscope-assisted gastrectomy due to early gastric carcinoma on July 9, 2002 was admitted to our hospital on November 27, 2002 with pyrexia and non-productive cough. He had been treated for Helicobacter pylori with clarithromycin, amoxicillin, and lansoprazole for a week and clarithromycin, amoxicillin, and omeprazole for another week after the operation. The laboratory data revealed hypoxemia and the chest radiograms and CT films showed the reticular shadows especially in the right lower lung field. After the cessation of all drugs, his symptoms were disappeared, and the reticular shadows in the chest radiograms also gradually improved Drug-induced lymphocyte stimulation test (DLST) was positive only for amoxicillin. Although the challenge test for amoxicillin was not performed, we diagnosed this case the drug-induced pneumonitis because of these clinical, laboratory findings.
