To the Editor.—
Rubella is usually a mild viral illness with infrequent complications except in pregnant women, when infection of the fetus may occur. Because of the serious abnormalities that can occur in an infected fetus,1 it is important that the correct diagnosis be made. We recently saw a young woman with a viral exanthem and an oral lesion suggesting herpangina who showed a rising titer to rubella. Although red macules or petechiae (Forchheimer sign) on the soft palate have been described,2 this oral lesion has not been previously noted.
Report of a Case.—
A 22-year-old single woman was seen with the complaints of sore throat, feeling poorly, and a rash of several days duration. She had been taking a combination pill containing aspirin and chlorpheniramine for her symptoms. The abnormalities noted on physical examination were a temperature of 38.4 C (101.1 F), discrete and confluent erythematous macules
