Malignant syphilis (also known lues maligna) is a rare and severe variant of secondary syphilis. It is most commonly seen in patients who are infected with human immunodeficiency virus (HIV), and rarely, it can occur in immunocompetent individuals. The exact mechanism of the development of malignant syphilis is not clear. It could probably be associated with immunosuppression, inappropriate immune response of the host, or virulent strain of Treponema pallidum. Coexistence of immunosuppression and inappropriate immune response may predispose to develop malignant syphilis in HIV-infected patients with immune reconstitution inflammatory syndrome. Herein, we report the first case of malignant syphilis after adalimumab therapy for Crohn's disease due to bariatric surgery and discuss the underlying possible pathogenic mechanisms.

Syphilis, caused by the spirochete , is a sexually transmitted infection (STI) that has seen a resurgence worldwide, particularly among populations at a higher risk of co-infection with human immunodeficiency virus (HIV). The disease typically progresses through distinct stages: primary, secondary, latent, and tertiary, each with specific clinical manifestations. Secondary syphilis is characterized by systemic involvement and various mucocutaneous symptoms, including a maculopapular rash that frequently involves the palms and soles along with fever, lymphadenopathy, and mucous membrane lesions.
