“…The dermoscopic criteria of plaque psoriasis (PP) were first described more than a decade ago, while further research revealed that a repetitive dermoscopic pattern of regularly distributed red dots and white scales typifies virtually all psoriatic plaques, including clinically atypical cases [2,3,4,5,6,7,8]. Recently, dermoscopy was assessed as an accurate method to differentiate between PP and other inflammatory skin diseases commonly included in the differential diagnosis, namely dermatitis, lichen planus and pityriasis rosea [8].…”

Background: Scarce evidence exists on the dermoscopic pattern of psoriasis on specific body sites. Objective: To describe the dermoscopic characteristics of psoriatic plaques located on the scalp, face, folds, palms, soles and genitalia. Methods: Dermoscopic images of psoriatic lesions located on the aforementioned body sites were retrospectively evaluated for the presence of predefined criteria. Results: A total of 139 lesions from 85 patients were included in the study. Dotted vessels were the commonest dermoscopic criterion (97.1%) followed by white scales (64.7%), while vessel distribution was regular in 87.7% of cases. Regularly distributed dotted vessels represented a constant finding in all locations, while the frequency of white scales varied significantly among different body sites. Conclusion: The well-known dermoscopic criteria of psoriasis can also be seen in lesions located on the scalp, face, palms, soles, folds and genitalia, with the frequency of white scales varying among different body sites.

“…Dermoscopic evaluations of psoriasis lesions on the trunk or extremities represented a homogenous vascular pattern of red dots/ globules [10][11][12][13][14]. Videodermoscopic observations of psoriasis lesions on the scalp often reveal interfollicular twisted loops, which are seen as red dots/globules at lower magnifications and as polymorphous beaded circles at higher magnifications when the probe is positioned vertically on the scalp [15].…”

“…Biopsy may be needed; even so, there are times when histopathological investigation can be inadequate for diagnosis. Dermoscopic examinations of psoriasis and seborrheic dermatitis lesions yielded different morphologies especially in the microvascular structures so it can be useful in differentiating these diseases [10][11][12][13][14][15][16][17][18][19]. In this study we investigated the usefulness of dermoscopy in the clinical differentiation of psoriasis and seborrheic dermatitis on the scalp and as distinct from previous studies, we also evaluated correlation of dermoscopic findings with disease severity.…”

Dermoscopy has frequently been used for hair and scalp disorders. Dermoscopic examinations of psoriasis and seborrheic dermatitis lesions yielded different morphologies. This study aimed to investigate the usefulness of dermoscopy in the clinical differentiation of psoriasis and seborrheic dermatitis on the scalp and additionally to evaluate its capacity in determining disease severity. The study included 46 psoriasis and 50 seborrheic dermatitis patients who were clinically diagnosed and had scalp lesions. Dermoscopic images taken from lesional scalp were then reviewed for microvascular patterns. In addition, we assessed the severity of scalp disease and looked for a correlation with these patterns. The frequency of twisted loops, glomerular vessels, red dots/globules, and polymorphous beaded lines/circles were statistically higher in the psoriasis group, whereas the frequencies of simple loops and arborizing vessels were statistically higher in the seborrheic dermatitis group (p<0.001). There was no significant difference in the frequency of featureless areas between two groups (p=0.579). There was no correlation with disease severity and dermoscopic findings. In conclusion, dermoscopy is a valuable and easy-to-use tool for differentiating psoriasis and seborrheic dermatitis on the scalp even if it doesn't have enough strength to determine disease severity. In addition, there is some diversity and ambiguity concerning terminology, which can be resolved with future studies and the establishment of conventional terms.

“…The dermoscopic hallmark of lichen planus is the Wickham striae, which suggests that it is highly sensitive and a specific criterion for the diagnosis of lichen planus [8,14] . Wickham striae can appear as pearly-whitish structures, and rarely as yellow or blue-white ones.…”

“…Wickham striae can appear as pearly-whitish structures, and rarely as yellow or blue-white ones. Its morphological patterns vary from reticular, which is the most common, to linear, annular, round or displaying a -radial streaming‖, -leaf venation‖ or -starry sky‖ patterns [8,[14][15][16][17] . The Wickham striae are commonly surrounded by dotted, globular, and/or linear vessels, mainly localized at the periphery of the lesion.…”

Abstract:Over the last few years, dermoscopy has been shown to be an effective diagnostic tool in assisting the noninvasive diagnosis not only of skin tumors but also of various general dermatological disorders. The use of dermoscopy has offered a new morphological dimension supporting the diagnosis and clinical follow-up of several dermatological conditions. Within the last years, dermoscopy is gaining ground in general dermatology as well. Among the large spectrum of skin infections, specific dermoscopic patterns have been described for common skin infections such as viral warts, molluscum contagiosum, scabies, and pediculosis, as well as for tinea nigra, tungiasis, and cutaneous larva migrans. Also, common skin disorders such as psoriasis, pityriasis rosea or lichen planus show characteristic dermoscopic patterns. The aim of this article is to provide an overview of the use of dermoscopy in general dermatology by analyzing the dermoscopic differential diagnosis of relatively common dermatological disorders grouped according to their clinical characteristics.
