Genital fixed drug eruptions.

Area of Science:

• Dermatology
• Pharmacology

Background:

• Fixed drug eruptions (FDEs) can manifest with genital involvement.
• Genital FDEs may present differently in terms of patient presentation and diagnosis.

Purpose of the Study:

• To investigate the clinical characteristics of genital fixed drug eruptions.
• To identify common causative agents and diagnostic methods for genital FDEs.

Main Methods:

• A retrospective study of 29 patients with genital fixed drug eruptions over one year.
• Diagnosis primarily based on drug history and confirmed with provocation tests.
• Classification of patients based on lesion location: exclusively genital vs. generalized cutaneous lesions.

Main Results:

• Fifteen patients had exclusively genital lesions, while 14 had additional cutaneous lesions.
• Patients with exclusively genital lesions sought medical attention significantly earlier.
• Tetracycline was the most common causative drug, followed by oxyphenbutazone and acetylsalicylic acid.

Conclusions:

• Early consultation is crucial for patients presenting with exclusively genital fixed drug eruptions.
• Thorough drug history and provocation testing are essential for diagnosing genital FDEs.
• Tetracycline, oxyphenbutazone, and acetylsalicylic acid are frequent culprits in genital fixed drug eruptions.
