An autopsy case of malignant lymphoma with Lyell's syndrome.

We present a case of fatal Lyell's syndrome which developed following a CT examination using omnipaque 3000 contrast medium. A 59-year-old man was suffering from malignant lymphoma. He was readmitted to this hospital due to relapse of fever and lymph node swelling. On the day of readmission, generalized erythema, purpura, and mucosal erosions developed after a CT examination. Steroids and chemotherapy were ineffective, and he expired approximately two weeks after admission. Drug-induced dermatopathy or leukemic cell infiltration in the skin was clinically suspected. Histological findings disclosed toxic epidermal necrolysis.
