Genital Involvement in Bullous Fixed Drug Eruption.

Bullous fixed drug eruption (FDE) is a severe reaction due to drug intake and requires specific management in dermatology. The sites of predilection are the lips, trunk, genitalia, and perineal area. The aim of our study was to assess the features and outcomes of bullous FDE with genital involvement through a retrospective study of 18 years (2000-2017) conducted in the Dermatology Department of Habib Thameur Hospital. Ten patients were included in the study. The ratio of men to women was 6.4. The mean age of the patients was 46.3 years. The most frequently affected genital site in men was the glans penis. Nonsteroidal anti-inflammatory drugs were the most frequent drugs associated with genital bullous FDE, followed by paracetamol and trimethoprim-sulfamethoxazole. Residual hyperpigmentation of the genitals was not observed in our patients. Genital involvement in bullous FDE is more frequent in men.
