“…However, it is also present in the acute form of alopecia areata . Yellow dots were observed in 6–100% (mean value, 62%) of patients with alopecia areata . Differences in the reported frequency of this trichoscopic finding may be attributed to skin phototypes (it has been hypothesized that yellow dots are generally less visible in populations with yellowish or dark color of the skin), type of dermoscopy device, as well as different shampooing habits between European, Asian and Latin American cultures .…”

The diagnosis of alopecia areata is usually based on clinical manifestations. However, there are several hair and scalp disorders that share similar clinical features with alopecia areata, such as tinea capitis, trichotillomania or traction alopecia. Trichoscopy as a fast, non-invasive and easy-to-perform technique may help to identify subtle details and establish the correct diagnosis. The aim of this review is to present the spectrum of trichoscopic findings in alopecia areata. A systematic review of the published work was performed by searching the PubMed, Scopus and EBSCO databases, complemented by a thorough hand search of reference lists. Of 427 articles retrieved, 30 studies were eligible for quantitative analysis. The reported features of alopecia areata were: yellow dots (6-100% patients), short vellus hairs (34-100%), black dots (0-84%), broken hairs (0-71%) and exclamation mark hairs (12-71%). Tapered hairs (5-81%) were reported in few studies, but a relatively high frequency of this finding in alopecia areata may indicate their important role in the differential diagnosis of hair loss. Rarely reported features, which include upright regrowing hairs (11-96%), pigtail (circle) hairs (4-61%) and Pohl-Pinkus constrictions (2-10%), may also be helpful in the diagnosis of alopecia areata. There is no pathognomonic trichoscopic marker for alopecia areata and the most common trichoscopic features are not the most specific. Therefore, the diagnosis should be based on the coexistence of several trichoscopic findings, not on the presence of a single feature.

“…For instance, Amer et al [39] reported that the most frequent dermoscopic feature of tinea capitis in an Egyptian population was comma hairs, first described by Slowinska et al [40], followed by zigzag hairs, found in 60 and 30% of their patients, respectively. Other features of tinea capitis reported in black scalp include black dots, hair casts, broken hairs, clip or question mark hairs, and Morse codeshaped hair [4,34,39,41]. Trichotillomania Few reports have been published about the trichoscopic characteristics of trichotillomania in dark skin [26,[42][43][44].…”

Trichoscopy (dermoscopy of the hair and scalp) is a technique that improves diagnostic accuracy and follow-up with hair and scalp disorders. Although several studies of trichoscopy have been made in Caucasian and Asian populations, little has been published regarding trichoscopy findings in skin of color, despite the great prevalence of hair diseases in populations with this kind of skin. The aim of this review was to describe the trichoscopic features of normal scalp and of hair disorders in patients with dark skin phototypes. This will help dermatologists to distinguish between unique trichoscopic features of dark skin, and allow them to provide more accurate diagnoses and treatments for these patients.

Amaç: Çocuklarda saç ve saçlı deri hastalıkları geniş bir yelpazede incelenir. Başlangıç yaşı ve klinik paternlerine göre ayırıcı tanıda farklı hastalıklar düşünülür. Bu çalışmada pediatrik dermatoloji (PD) polikliniğine başvuran saç-saçlı deri hastalıklarının sıklığını ve başlıca klinik özelliklerini retrospektif olarak değerlendirmeyi amaçladık. Yöntem: 2011 Eylül-2013 Ağustos tarihleri arasında Afyon Kocatepe Üniversitesi Hastanesi PD polikliniğine başvuran 18 yaş altı 2641 hastanın dosyası taranarak saç-saçlı deri hastalığı olan 159 hasta değerlendirmeye alındı. Hastaların demografik ve klinik bilgileri kaydedilerek uygun analizler yapıldı. Bulgular: Hastaların (90 kız ve 69 erkek) yaş ortalaması 9,92±5,28 (2 ay-17 yıl) idi. Tüm yaş grupları arasında en sık görülen hastalıklar seboreik dermatit, alopesi areata, tinea kapitis, telojen effluviyum ve psoriasis idi (sırasıyla, %26,4, %19,5, %13,2, %11,9 ve %11,9). Saç dökülmesi tüm hastaların %47,8'sinde mevcuttu. Saç dökülmesi analizinde saç çekme testi ve trikoskopi en sık kullanılan yöntemler iken, biyopsi en nadir kullanılan yöntemdi (%72,3, %40,9 ve %5,0). Sonuç: Saç dökülmesi kozmetik kaygılar nedeniyle her yaşta önemlidir. Pediatrik yaş grubunda en sık non-sikatrisyel akkiz alopesiler görülür. Objective: The hair and scalp diseases in children are studied in a wide range. Various diseases were considered in the differential diagnosis according to the age of onset and clinical patterns. We aimed to retrospectively evaluate the frequency and main clinical features of hair and scalp diseases in patients admitted pediatric dermatology (PD) outpatient clinic. Methods: 159 patients with hair and scalp diseases which were distinguished among the records of 2641 patients under 18 years of age, who were admitted to PD outpatient clinic of Afyon Kocatepe University Hospital. The demographic and clinical data were recorded from the files and appropriate analyses were performed. Results:The mean age of patients (90 females and 69 males) were 9.92±5.28 years (2 months-17 years). Seborrheic dermatitis, alopecia areata, tinea capitis, telogen effluvium and psoriasis were the most common diseases (26.4%, 19.5%, 13.2%, 11.9% and 11.9% respectively) Hair loss was present in 47.8% of cases. Hair pull test and trichoscopy were the most common diagnostic methods in the analysis of hair loss whereas biopsy was the least common (72.3%, 40.9% and 5.0). Conclusion:Hair loss is important at all ages due to cosmetic concerns. Non-scarring acquired alopecias were the most common in pediatric age group.
