Fixed Drug Eruption with Pigmentation Induced by Etoricoxib: A Case Report

Abstract

Fixed drug eruption with pigmentation is characterized by the appearance of erythematous or bullous lesions following the ingestion of certain medications. We present the case of a 23-year-old male patient who sought medical attention due to painful and pruritic lesions on the ventral surface of the penis, encompassing the glans, frenulum, and prepuce. The patient's history revealed prior consumption of etoricoxib and previous occurrences of similar lesions in the same region. After prescribing a topical corticosteroid for 5 days, the patient returned for follow-up, demonstrating clinical improvement with residual hyperpigmentation. Based on the history of etoricoxib use, previous episodes, and the characteristics of the lesions, a diagnosis of fixed drug eruption with pigmentation was established.
