This case is reported to present a new skin eruption, apparently caused by the ingestion of phenobarbital. The toxic reactions to this drug were described in 1927 by Jackson,1 who reviewed the literature and presented six cases of his own. The characteristic reaction is an erythematous rash, which may involve the entire body. Fever, gastro-intestinal symptoms and cerebral symptoms may develop. An enanthem and conjunctivitis have been observed. Jackson mentions a case that had been mistaken for measles. I have seen a similar measles-like toxic reaction in a 6 year old child who presented the entire clinical picture of rubeola except for Koplik spots.
