“…Several dermoscopic features have been established in DLE [3]. Active lesions show “red dots”, which are erythematous, polygonal, and concentric in structure, linked to dilated vessels and extravasated erythrocytes in perifollicular distribution on pathology [4,5]. Large, yellow-brown dots correspond to keratotic plugs in the dilated follicular ostia [3,2].…”

Dermoscopic features of discoid lupus erythematosus (DLE) depend on the stage of the lesions: active lesions include yellow-brown dots and red dots, whereas longstanding inactive lesions show absence of follicular openings, cicatricial milky red or white patches, structureless white and brown areas, and thick arborizing vessels. Loss of pinpoint white dots, blue-gray dots in a speckled pattern, and a peripheral pigmented network have been described on dermoscopy of DLE in dark skin. We report a blue-white veil as a novel dermoscopic feature in 2 cases of biopsy-proven DLE in African-American patients. Dry trichoscopy revealed a central white area surrounded by irregular patchy areas of confluent blue and brown pigment and an overlying white “ground-glass” hue. This corresponds on pathology to the hyperkeratosis overlying interface changes at the dermal-epidermal junction, with pigment incontinence and melanophages in the papillary dermis.

“…Red dots form a good prognostic indicator and indicate possible hair growth by Tosti et al . [8] The yellow dots observed in DLE are larger in size and represent follicular plugging. Both of these changes were better appreciated in polarized mode.…”

Aims:The aim was to study the trichoscopy features of selected hair and scalp conditions by two dermoscopic devices with different modes that is, polarized (noncontact) and nonpolarized (contact) mode.Materials And Methods:The present study included 11 clinical varieties of cases with total 112 patients, attending Sir Takhtasinh Hospital, Bhavnagar in the last 2 years. The clinical history was recorded for each case, and images were taken in both the Heine and DermLite II pro dermatoscope. We used polarized mode of the noncontact device (DermLite II) and the nonpolarized mode of the contact device (Heine) for our study.Statistical Analysis Used:Fisher's exact test to study dermoscopic observations for each mode.Results:We observed different nonscarring alopecia cases such as alopecia areata, androgenetic alopecia, trichotillomania, and tinea capitis. Scarring alopecia included discoid lupus erythematosus, lichen planopilaris, pseudopelade of Brocq, systemic lupus erythematosus. Scaling disorders included the psoriasis and seborrheic dermatitis. Furthermore, infestations like pediculosis capitis were included in the study. Various features were divided into follicular, interfollicular, pigmentary, vascular and hair shaft patterns. Each of the features was correlated in both the Heine (nonpolarized) and DermLite II (polarized) dermoscope, and observational finding was put forward accordingly.Conclusions:Various variations were observed in the documentation of dermoscopic patterns of the two dermatoscopes with certain features such as vascular patterns, scaling, and reticular pigmentation being better appreciated in polarized mode, while certain features were better documented in nonpolarized mode that is, black dots and tapered hair.

“…They are more easily observed using video trichoscopy than with handheld trichoscopy [18]. The combination of large numbers of yellow dots and short growing hairs is a feature of AA incognita [22]. For the diagnosis of alopecia areata, other signs of alopecia areata should be taken into account, because isolated yellow dots may be seen in trichotillomania, hypotrichosis simplex, and even tinea capitis, as stated by Inui [23].…”

Background. Diagnosis of patchy hair loss in pediatric patients is often a matter of considerable debate among dermatologists. Trichoscopy is a rapid and noninvasive tool to detect more details of patchy hair loss. Like clinical dermatology, trichoscopy works parallel to the skin surface and perpendicular to the histological plane; like the histopathology, it thus allows the viewing of structures not discovered by the naked eye. Objective. Aiming to compare the different trichoscopic features of tinea capitis and alopecia areata in pediatric patients. Patients and Methods. This study included 40 patients, 20 patients with tinea capitis and 20 patients with alopecia areata. They were exposed toclinical examination, laboratory investigations (10% KOH and fungal culture), and trichoscope examination. Results. Our obtained results reported that, in tinea capitis patients, comma shaped hairs, corkscrew hairs, and zigzag shaped hairs are the diagnostic trichoscopic features of tinea capitis. While in alopecia areata patients, the most trichoscopic specific features were yellow dots, exclamation mark, and short vellus hairs. Conclusion. Trichoscopy can be used as a noninvasive tool for rapid diagnosis of tinea capitis and alopecia areata in pediatric patients.
