Fixed drug eruptions- A Case Report

Abstract

Fixed drug eruption (FDE) is typically establishes as round or oval, sharply delineated erythematous or edematous plaques. Essentially it is a drug-induced cutaneous reaction that happens at the similar site with each exposure to a specific medication. A extensive spectrum of drugs can occasionally give rise to numerous contrary orofacial manifestations, predominantly dry mouth, taste disturbances, oral mucosal ulceration, and/or gingival swelling. However, the etiology of the FDE is still unknown, it is a delayed type of hypersensitivity reaction that occurs as lesions. By limiting the use of the term allergic to those reactions that are immunologically arbitrated or can reasonably be reputed to be, approximations are that drug allergy may account for 6–10% of these adverse reactions.
