Erythema multiforme exudativum Stevens-Johnson syndrome) has been described in association with the administration of numerous medications, including sulfonamides,1-6 penicillin,7 thiouracil,5 phenylbutazone,8 salicylates, codeine,9 Fowler's solution,10 phenolphthalein,7 barbiturates,11,12 trimethadione,13 and diphenylhydantoin.14-16 A reversible, lupus-like disease, characterized by the L.E. cell phenomenon, with or without renal and systemic involvement, has also been attributed to medications such as hydralazine,17-22 penicillin,23,24 phenylbutazone,17 sulfadiazine,25,26 and methylphenylethylhydantoin (Mesantoin) .27It is the purpose of this paper to report the simultaneous occurrence of erythema multiforme exudativum and a reversible, lupus-erythematosus-like disease in 2 adoles-cent girls, as well as acute lupus erythematosus alone in a 4-year-old boy, following medication with anticonvulsant drugs.
Report of CasesCase 1.\p=m-\Atthe age of 7\ m=1/ 2\years, this girl began experiencing petit mal seizures characterized by momentary lapses of consciousness, substantiated by typical 3-per-second spike and wave dis¬ charges on the electroencephalogram. She was given trimethadione (Tridione), 900 mg. daily, and phénobarbital, 45 mg. daily. Over the next 3Vi years, the seizures were controlled by variable amounts of these 2 medications.In 1954, at the age of 11 years, the patient de¬ veloped erythema multiforme exudativum (Stevens-Johnson syndrome), with scattered bullous skin lesions, mucous membrane vesiculation and ero¬ sion, conjunctivitis, fever, and malaise. Laboratory studies included a hemoglobin of 14 gm. '% ; a white blood count of 5,100, with 38% neutrophils, 53% lymphocytes, and 9% eosinophils; and an erythrocyte sedimentation rate of 10 mm/hour. Urinalysis was normal. Two L.E. clot tests were negative. The patient was treated with hydrogen peroxide soaks and 1% neomycin ointment applied to the more severe local lesions. Trimethadione and phénobarbital were discontinued, and the anti¬ convulsant medication changed to Mebroin (a synergistic combination of mephobarbital and diphenylhydantoin) 3 tablets daily, and paramethadione (Paradione), 300 mg. a day.Mild skin lesions recurred intermittently during the next 3 years. Then, in 1957, at age 14, the patient developed fever, cough, more extensive oral and genital lesions, and paronychia (Fig. 1).The lesions were identified as a recrudescence
