“…Large, yellow-brown dots correspond to keratotic plugs in the dilated follicular ostia [3,2]. Longstanding, inactive lesions show absence of follicular openings and cicatricial milky red or white patches and structureless white and brown areas [3,6,7]. Thick arborizing, monstrous vessels may be noticed too [3,5].…”

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.

“…Similar findings can be observed in the pathology of DLE lesions, such as those presented in Figure 2. The structureless, white areas described in end-stage lesions of DLE are different because they correspond histologically to diffuse dermal fibrosis [7]. …”

“…SD was reported to exhibit dotted vessels with a patchy distribution and yellow scales and, consequently, discrimination between facial psoriasis and SD might be enhanced by the assessment of the scale color, similarly to other body sites [10]. Rosacea, granulomatous disorders and discoid lupus erythematosus display characteristic dermoscopic criteria that facilitate their diagnosis, namely polygonal vessels, yellow-orange patches and follicular disturbances, respectively [10,14,15,16]. …”

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.

“…Over the last few years, several studies have shown that dermoscopy may be a useful tool to assist the non-invasive diagnosis of various inflammatory skin diseases [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] , including classic GA [20][21][22][23][24] . Indeed, albeit dermoscopic examination of this dermatosis has been reported to show heterogeneous findings, the use of such a technique may come in handy to support the distinction from its main differential diagnoses as they typically show a different appearance [20][21][22][23][24] .…”

Dermoscopy of Granuloma Annulare: A Clinical and Histological Correlation Study

et al. 2017

Background: Dermoscopy of granuloma annulare has been investigated by several studies, but none of them took into account the variability of dermoscopic findings according to clinical characteristics and/or histological subtype. Objective: To describe the dermoscopic features of classic granuloma annulare and seek possible dermoscopic clues related to specific clinical findings/histological subpatterns. Methods: A representative dermoscopic image of a target lesion (the most active lesion underwent histological examination) was retrospectively assessed for the presence of specific morphological findings, correlating them with clinical variables, i.e. disease duration and extension (localized or generalized) and clinical aspect (annular or non-annular) and localization (trunk or extremities) of the biopsied lesion, and with histological subtype. Results: A total of 25 lesions from 25 subjects were analysed; an “interstitial” histological variant was detected in 11 cases, while a “palisading granuloma” histological pattern was found in 14 instances. The most common dermoscopic findings included blurry vessels having variable appearance (dotted, linear-irregular, and branching) over a more or less evident pinkish-reddish background, followed by whitish and/or yellowish-orange areas. Additional findings were rosettes, crystalline structures, and whitish scaling. No difference (p > 0.05) in the frequency of dermoscopic features according to clinical findings was found, while we observed a strict association (p < 0.001) between the presence of yellowish-orange structureless areas on dermoscopy and “palisading granuloma” histology. Conclusion: The dermoscopic aspect of granuloma annulare is independent from clinical features but varies according to histological subtype, with the detection of yellowish-orange colour being indicative of the “palisading granuloma” variant.
