“…9 In cases of AA, dermoscopic findings include clusters of short vellus hairs (shorter than 10 mm), as well as yellow dots and dystrophic hair (black dots or cadaverized hair) and exclamation mark hair. 2,3 Ross et al were the first to observe yellow dots in a patient with trichotillomania; however, biopsy revealed AA in the same patch. 3 In the studies conducted by Inui et al, a few yellow dots were found in cases of androgenetic alopecia and in trichotillomania.…”

“…2,3 Ross et al were the first to observe yellow dots in a patient with trichotillomania; however, biopsy revealed AA in the same patch. 3 In the studies conducted by Inui et al, a few yellow dots were found in cases of androgenetic alopecia and in trichotillomania. These authors suggest that in trichotillomania all the yellow dots should contain the black dots that constitute the remains of the dead hair follicles, which 2 Nevertheless, yellow dots without black dots may be present albeit to a lesser extent.…”

“…In accordance with the literature, this finding is considered pathognomonic of AA. 2,3 The hairs with fraying ends that are seen in trichotillomania may resemble exclamation mark hairs (Figure 2A), hampering differentiation between the two conditions, particularly when both trichotillomania and AA are present.…”

“…2 A key diagnostic finding in patients with AA that is considered pathognomonic by some authors is exclamation mark hair. 2,3 Considering that prognoses and treatment are different in trichotillomania and AA, it would be useful to be able to establish these differences using noninvasive methods such as dermoscopy, since histopathology may be inconclusive and the biopsy procedure traumatic, particularly in children.…”

BACKGROUND: Trichotillomania and patchy alopecia areata have similar clinical and dermoscopic features. OBSERVATIONS: In trichotillomania, dermoscopy shows decreased hair density, short vellus hair, broken hairs with different shaft lengths, coiled hairs, short vellus hair, trichoptilosis, sparse yellow dots, which may or may not contain black dots and no exclamation mark hairs. CONCLUSIONS: In the case of patchy alopecia and broken hairs, the absence of exclamation mark hairs suggests a diagnosis of trichotillomania. On the other hand, the finding of yellow dots without black dots does not exclude it. Keywords: Alopecia; Anxiety disorders; Dermoscopy; Differential Diagnosis; Nail biting Resumo: INTRODUÇÃO: Tricotilomania e alopecia areata em placa possuem características clínicas e dermatoscópicas semelhantes. OBSERVAÇÕES: O exame dermatoscópico da tricotilomania revela densidade capilar diminuída, cabelos fraturados em diferentes tamanhos, enovelados e vellus, tricoptilose, pontos amarelos com ou sem pontos pretos e ausência de cabelos em "ponto de exclamação". CONCLUSÃO: No contexto de alopecia em placa e cabelos fraturados, a ausência de "pontos de exclamação" sugere o diagnóstico de tricotilomania. Por outro lado, o achado de pontos amarelos sem pontos pretos não afasta o mesmo.

“…Evaluations can be categorized as invasive (e g, scalp biopsies), semi-invasive (e g, trichogram), or noninvasive (e g, hair counts, microscopic evaluation, trichoscopy). Each of these approaches, when interpreted with the comprehensive clinical picture, can provide valuable insights into patient diagnosis, treatment and monitoring 7 .More recent studies have accumulated evidence that use of dermoscopy of hair and scalp (trichoscopy) in the clinical evaluation of hair disorders improves diagnostic capability beyond simple clinical inspection [8][9][10][11] . Without treatment, AGA takes a chronic progressive course with an average hair loss of 5-6 % annually with great inter individual variability 12,13 .…”

Background: Androgenetic alopecia (AGA) more commonly known as male pattern baldness affects up to 50% of men worldwide. Tretinoin prolongs anagen phase and increases percutaneous absorption of minoxidil three fold. Azelaic acid is an inhibitor of 5 alpha reductase and could be an effective agent in the treatment of androgen related pathology of human skin. Aims and Objective: 1) To study the efficacy of topical minoxidil 5% in treatment of androgenetic alopecia. 2) To study the efficacy of combination of topical minoxidil 5%, topical azelaic acid 1.5% and topical tretinoin 0.01% in treatment of androgenetic alopecia. 3) To compare the efficacy of foresaid topical preparation in treatment of androgenetic alopecia Setting: Outpatient department of Dermatology, Venerology Leprology of a tertiary health care centre with an attached medical college. Material and methods: Topical minoxidil 5 % lotion was used in 23 (50%) patients of the present study. Combination of topical minoxidil 5%, azelaic acid 1.5 % and tretinoin 0.01 % lotion was used in 23 (50 %) patients of the present study. Statistical analysis used: Epi info version 7. Results: There was statistically significant increase in hair number and thickness after treatment in both the groups. The comparison of the increase of hair number and thickness was statistically insignificant. Conclusions: Topical Minoxidil 5% is equally effective to combination of topical Minoxidil 5%, azelaic acid 1.5% and tretinoin 0.01% in treatment of androgenetic alopecia.
