Fixed Drug Eruption to Ibuprofen in Daughter and Father

Fixed drug eruption (FDE) is a common cutaneous reaction which may be seen in reaction to several medications. The usual etiologic agents associated with FDE are phenazones, sulfonamides, and tetracyclines. Often the causative agent is made out from the patient’s history; in some cases, oral challenge or topical testing may be required. The pathophysiology of FDE is unclear. Cell-mediated, rather than humoral immunity is thought to be involved. Herein we report a case of FDE in a daughter and father.
