“…Hair loss is a manifestation of secondary syphilis scarcely reported in the literature. 5 It may appear as non-specific, diffuse effluvium, but the "moth-eaten" irregular patchy hair loss, as seen in our patient, is the most characteristic scalp pattern. 5 SA most commonly affects the parieto-occipital area, although any site can be involved.…”

Alopecia syphilitica is a less common clinical manifestations of secondary syphilis. It is uncommon for hair loss to be the sole or predominant manifestation, as hair loss is the chief clinical and histologic differential diagnosis of. The main difference between alopecia areata and Alopecia syphilitica is the detection of Treponema pallidum in syphilis. We present the case of a 21- year-old belgium man with different patches of non-cicatricial alopecia of his scalp. The patient denied previous history of genital or other skin lesions. Laboratory evaluation was positive for syphilis. The diagnosis of alopecia syphilitica was made and he was treated with single intramuscular injections of benzathine penicillin. The lesions improved with treatment in all the patients who attended follow-up. Dermatologists should maintain a high level of clinical suspicion for this uncommon manifestation of syphilis, particularly when it is the only symptom.

“…Other non-infection-specific findings have been reported as black dots, hypopigmentation of hair shafts, yellow dots, irregularly dilated blood capillaries, broken and “zigzag” hair shafts. 42 , 43 , 44 , 45 A reddish-brown pigmentation in areas of scalp alopecia may be present but it is not evident in areas of alopecia of the beard and eyebrows. 42 , 45 This pigmentation has regressed after antibiotic therapy and it has been speculated that it was due to an immune response-induced small vessel vasculitis against T. pallidum located in the blood vessels of the perifollicular epithelium.…”

Dermoscopy is an essential in vivo diagnostic technique in the clinical evaluation of skin tumors. Currently, the same can also be said about its implications when approaching different clinical situations in Dermatology. A growing number of reports on dermatological scenarios and diseases have been published, in which dermoscopy has been of great diagnostic help. The term “entomodermoscopy” was coined to describe dermoscopic findings in skin infestations and also in dermatoses of infectious etiology. In part I of this article, the main dermoscopic descriptions of zoodermatoses and bacterial infections will be addressed. In many of them, such as scabies, pediculosis, myiasis, and tungiasis, it is possible to identify the pathogen and, consequently, attain the diagnosis more quickly and use the technique to follow-up therapeutic effectiveness. In other situations that will be described, dermoscopy can allow the observation of clinical findings with greater detail, rule out differential diagnoses, and increase the level of confidence in a clinical suspicion.
