“…In a case of Alternaria chlamydospora infection of the scalp no comma hairs were observed (37). A recent case report showed that hair trichoscopy features of tinea capitis dissolve with successful therapy and hair re-growth (38). Other common trichoscopy features of tinea capitis in our study included black dots, broken hairs, block hairs, i-hairs, and zig-zag hairs.…”

Differential diagnosis of trichotillomania is often difficult in clinical practice. Trichoscopy (hair and scalp dermoscopy) effectively supports differential diagnosis of various hair and scalp diseases. The aim of this study was to assess the usefulness of trichoscopy in diagnosing trichotillomania. The study included 370 patients (44 with trichotillomania, 314 with alopecia areata and 12 with tinea capitis). Statistical analysis revealed that the main and most characteristic trichoscopic findings of trichotillomania are: irregularly broken hairs (44/44; 100% of patients), v-sign (24/44; 57%), flame hairs (11/44; 25%), hair powder (7/44; 16%) and coiled hairs (17/44; 39%). Flame hairs, v-sign, tulip hairs, and hair powder were newly identified in this study. In conclusion, we describe here specific trichoscopy features, which may be applied in quick, non-invasive, in-office differential diagnosis of trichotillomania.

“…After 8 weeks of treatment, itch was reduced and alopecia was improved (Fig. 1b), pilotraction was negative, and trichoscopy revealed complete absence of comma hairs as reported in the literature [5]. …”

“…Moreover, comma hairs have been hypothesized to represent cracking and bending of hyphae-filled hair shafts [7]. Normalization of trichoscopy after 8 weeks is a good prognostic sign for recovery in TC [5], and it was confirmed by mycological examination. TC is unusual in adulthood [8, 9], but a growing number of authors have reported an increase in TC among adults, particularly menopausal and elderly women [9].…”

Dermatomyositis (DM) is an autoimmune disease that primarily affects the skin and muscles, but may also have a systemic involvement. The frequency of scalp involvement in DM varies from 28 to 82% and is often encountered as part of a DM flare. However, it frequently presents as a treatment-resistant disease, and patients reporting no improvement with conventional therapies require further investigation. We report a case of tinea capitis (TC) in a 79-year-old woman affected by DM with scalp involvement which did not respond to conventional therapies. Thanks to trichoscopy we could detect “comma hairs,” “zigzag hairs,” and “pigtail hairs” at scalp examination, made the right diagnosis of TC, and instituted the best treatment without delay.

“…3,4,5 Furthermore in a recent case report the authors showed that hair trichoscopy features of tinea capitis in a patient disappeared with successful therapy and hair regrowth. 13 In veterinary dermatology, screening tests for dermatophytosis include Wood's-lamp examination and direct microscopic examination of the fluorescent hairs. 11 In this study the comma-like structures observed with the dermoscope in cats with dermatophytosis were confirmed as infected hairs at microscopic examination also in three cats that were negative to Wood's lamp examination.…”

Background -Dermoscopy is a non invasive technique allowing rapid and magnified in vivo observation of the skin and structures that lie beneath the skin surface. Various congenital and acquired hair shaft abnormalities may be also evaluated by dermoscopy and characteristic features of Microsporum canis-induced tinea capitis and trichotillomania in people have also been reported. Objectives -To describe the dermoscopic findings observed in cats with patchy alopecia due to Microsporum canis infection and in cats with self-inflicted hair loss. Animals -Twenty-four client-owned cats presented to a private veterinary referral practice. Methods -Dermoscopy was performed with both an handheld non-polarized light dermoscope at 10-fold magnification and a videodermoscope at 40-fold magnification. Results -At 10-fold magnification, the most characteristic findings observed in circumscribed lesions of cats with dermatophytosis were opaque, broken hairs slightly curved with an homogeneous thickness (comma-like structures) and a variable amount of brown-to-yellow greasy scales. In cats with self-induced alopecia, multiple hairs with a normal shaft suddenly and cleanly broken at different lengths, short tufts of hairs broken at equal level , hook-like and coiled hairs were observed. By videodermoscopy, hair shaft thickness was also measured. Conclusions -This observational descriptive study suggests that dermoscopy may represent an in vivo non-invasive technique helpful in differential diagnosis of patchy alopecia in cats.
