Syphilitic hair loss

Syphilic hair loss: About 10% of patients with secondary syphilis occur. This is caused by syphilitic infiltration of hair follicles, fine blood vessels in the hair area are blocked, and poor blood supply is caused. Presented as syphilitic alopecia areata or diffuse hair loss, the former is a bald spot of about 0.5 cm, which is moth-like. Diffuse hair loss, large area, thinning, uneven hair length. It is also common in the temporal, top and occipital, eyebrows, eyelashes, beards and pubic hair. Treponema pallidum was localized in secondary syphilis baldness. Moreover, the site of Treponema pallidum is basically the same as the site of cell infiltration, so it is thought that syphilitic baldness may be related to the site of treponema pallidum invasion. Treponema pallidum does not invade the hair nipples and invades the upper part of the hair follicles. Therefore, incomplete bald patches are predominant in syphilitic baldness. However, syphilitic hair loss is not permanent. If treated in time, hair can be regenerated in 6-8 weeks, even without treatment.
