| Abstract: | A 54-year-old Japanese man demonstrated a sultamicillin-induced hilar and mediastinal lymphadenopathy with hypersensitivity pneumonitis. A positive lymphocyte stimulation test for sultamicillin and a decreased CD4/CD8 ratio of lymphocytes in BAL fluid suggested that an alteration in cell-mediated mechanisms was responsible for the patient's symptoms. |
