Fixed drug eruption of the scrotum due to hydroxyzine hydrochloride (Atarax).

Fixed drug eruption describes a sharply localized dermatitis that characteristically recurs at the same site each time the offending drug is administered. Several drugs have been reported to cause this eruption, such as phenolphthalein, barbiturates, penicillin, and others. In this report, two children with fixed drug eruption of the scrotum due to hydroxyzine hydrochloride (Atarax) are described. To the best of our knowledge, no such cases have been reported previously in children.
