ABSTRACT

Syphilis is a polymorphous disease caused by a Treponema pallidum infection. Syphilitic alopecia (SA) is a rare clinical presentation of secondary syphilis. Its prevalence ranges between 2.9 and 22.2%, although it could be underestimated due to its subtle presentation and its similarities with other diseases, therefore it is important to know the clinical and trichoscopic characteristics for its proper diagnosis. This article presents five clinical cases. Symptomatic SA and the moth-eaten or patchy pattern were the most common clinical forms. The involvement of the scalp and eyebrows occurred in 100 and 80% of the patients, respectively. The trichoscopic findings were: decrease in capillary density and erythema with or without hypopigmented areas occurring in 100% of the patients, blackheads, flexed and broken hairs of different lengths in 75%, vellus hair in 50% and hyperkeratosis perifollicular, dilated capillaries and exclamation mark hairs in 25%.
