Syphilitic alopecia
ICD-10 A51.32 is a billable code used to indicate a diagnosis of syphilitic alopecia.
Syphilitic alopecia is a manifestation of secondary syphilis, characterized by hair loss that occurs due to the systemic effects of the Treponema pallidum bacterium. This condition typically presents as patchy hair loss, often affecting the scalp, eyebrows, and eyelashes. The alopecia is a result of the inflammatory response to the infection, which can disrupt the normal hair growth cycle. Patients may also exhibit other systemic symptoms associated with secondary syphilis, such as mucous membrane lesions, rashes, and lymphadenopathy. Diagnosis is primarily clinical, supported by serological testing for syphilis, including non-treponemal tests (e.g., RPR, VDRL) and treponemal tests (e.g., FTA-ABS). Treatment involves the administration of benzathine penicillin G, which is effective in eradicating the infection and may lead to the regrowth of hair over time. Early diagnosis and treatment are crucial to prevent complications and further transmission of the infection.

Syphilitic alopecia is primarily caused by the systemic effects of the Treponema pallidum bacterium during secondary syphilis, leading to inflammation and hair loss.
