“…These dots signify active disease and correspond to the dilated vessels and red blood cell extravasation around the isthmus, with an overlying atrophic epidermis. This finding was later reported in the normal scalp by Pirmez et al 26 They suggested that the red dots were visualized due to rich vasculature enveloping the hair follicle and their presence represents viable follicles which are indeed associated with a better prognosis as originally stated. 25,26 Thick arborizing vessels or tortuous enlarged branching vessels have been described as a characteristic trichoscopic feature of DLE of the scalp.…”

Trichoscopy is an emerging technique for the evaluation of various hair and scalp disorders including primary cicatricial alopecias (PCAs). Early diagnosis of PCAs can lead to effective management and trichoscopy could be a useful aid during this process. Multiple studies have reported the trichoscopic features of PCAs, however, a focused review evaluating these disorders with their trichoscopic features is lacking. With the objective of evaluating the trichoscopic findings reported in the literature for various PCAs, we conducted a systematic literature search in PubMed and Embase. The search yielded 310 studies in a total of which 54 studies were included in our review. Majority of these studies originated from the Caucasian or Asian population. Through this review, we provide an overview of the frequent and specific trichoscopic findings in different PCAs with their clinical significance where applicable based on the current knowledge and identify the areas for future research.

“…It has been suggested that the overlying atrophic epidermis of DLE lesions would allow the visualization of the rich vascular net that naturally envelops the normal hair follicle. FRD in DLE lesions would therefore represent still viable hair follicles responsible for the better chance of hair regrowth reported in those patients . FRD have also been described in the eyebrows of patients with FFA .…”

“…was a red follicular pattern and was considered as a specific feature of scalp lesions of active lupus erythematosus of the scalp. These dots correspond to widened infundibula with dense perivascular lymphocytic in filtrates, dilated vessels, and extravasated erythrocytes [11,20]. The loss of this pattern in DLE may be a sign of hair follicle damage with poor prognosis [20].…”

Background:The diagnosis of Discoid Lupus Erythematosus (DLE) is usually made by clinical examination and by histopathology. Recently, dermoscopy has become an integral part in diagnoses of many inflammatory disorders and one of these is DLE. Aims:This research emphasizes the utility of dermoscopy in the assessing lesions of DLE from the point of activity of the disease. Patients and Methods:Thirty-one patients diagnosed with DLE were included in this study. The total number of examined lesions was 125 lesions. All of the lesions were assessed by dermoscopy at different stages of the activity of the diseases. Results:The dermoscopic features of DLE vary according to the stage of activity of the disease. There are characteristic dermoscopic features for the lesions of the scalp different from that of the body. In the active and early phase, the most common dermoscopic features were the presence of lesional and perilesional scales, follicular keratotic plugging, telangiectasia, arborized blood vessels, follicular red dots and perifollicular scales. In addition, there are less common dermoscopic features such as pigmentary changes, white rosettes and pinpoint white dots. For active scalp lesions, the follicular plugging and perifollicular scales were more prominent than that of the body DLE lesions. For inactive and late DLE lesions, the most significant dermoscopic changes were perifollicular whitish halos, variable patchy whitish hypopigmented areas, and the presence of white colored structureless areas. Conclusion:The present study provides new insights into the dermoscopic variability of DLE lesions at different levels of activity.
