POSTCOITAL FIXED DRUG ERUPTION IN A MAN SENSITIVE TO TRIMETHOPRIM-SULFAMETHOXAZOLE

We describe a 34-year-old patient with a probable fixed drug eruption caused by trimethoprim-sulphamethoxazole, having developed the eruptio n after sexual intercourse with his wife, who was taking the drug. The patient was known to be allergic to trimethoprim-sulphamethoxazole by history, and the lesion then recurred at the same site when the drug was administered orally to his wife. To the best of our knowledge, thi s is the first report describing postcoital fixed drug eruption. Physi cians should thus be aware of unusual and atypical forms of fixed drug eruption.
