Follmann balanitis in secondary syphilis.

Syphilitic balanitis is an uncommon rather underreported manifestation of primary syphilis initially described by Eugene Follmann and subsequently named after him. It is characterized by balanitis with or without a primary chancre and inguinal lymphadenopathy. Given its rarity, Follmann balanitis may be misdiagnosed with other causes of balanitis. Therefore, a strong clinical suspicion and awareness are crucial, particularly in the current resurgence of syphilis. With this background, we hereby report a case of Follmann balanitis in secondary syphilis, diagnosed based on clinical features, positive syphilis serology, and response to benzathine penicillin treatment.
