Abstract

Little is known about the dermoscopic features of scalp tumours. Objective To determine the dermoscopic features of scalp tumours. METHODS: Retrospective analysis of dermoscopic images of histopathologically diagnosed scalp tumours from International Dermoscopy Society members. RESULTS: A total of 323 tumours of the scalp from 315 patients (mean age: 52 years; range 3-88 years) were analysed. Scalp nevi were significantly associated with young age (65 years and sun damage. Atypical network and regression were predictive for thin (≤1 mm) melanomas, whereas advanced melanomas (tumour thickness > 1 mm) revealed blue white veil, unspecific patterns and irregular black blotches or dots. CONCLUSIONS: The data collected provide a new knowledge regarding the clinical and dermoscopy features of pigmented scalp tumours

Abstract

Background Several common inflammatory dermatoses, such as rosacea, seborrheic dermatitis (SD), discoid lupus erythematosus (DLE) and granulomatous skin diseases manifest as erythematous macules or plaques on the facial skin. Although clinical examination represents the cornerstone of diagnosis, the broad variety of clinical features and uncommon presentations of these diseases may cause at times diagnostic and therapeutic uncertainty. Dermoscopy, in addition to its well-documented value in evaluation of skin tumours, is continuously gaining appreciation also in the field of general dermatology. Objective To describe and compare the dermoscopic patterns of common facial inflammatory skin diseases including SD, erythematotelangiectatic rosacea (ER), sarcoidosis, lupus vulgaris (LV), DLE and granuloma faciale (GF). Methods Dermoscopic images of lesions from patients with histopathologically confirmed diagnosis of SD, ER, sarcoidosis, LV, DLE or GF were retrospectively evaluated for the presence of several criteria. Selection of the dermoscopic variables included in the evaluation process was based on the data available in the literature and on our preliminary observations. Results One hundred and fifteen dermoscopic images were included in the study. SD was dermoscopically characterized by dotted vessels and yellow scales, whereas ER was typified by a characteristic pattern of vascular polygons. Sarcoidosis and LV very commonly exhibited orange-yellowish areas and linear branching vessels. Features related to follicle abnormalities and linear branching vessels were the most common dermoscopic criteria of DLE and GF. Conclusions This study provides new insights into the dermoscopic variability in common facial inflammatory dermatoses.

Abstract

Background: Among the various types of basal cell carcinoma, the sclerodermiform variant has a high risk of recurrence and local invasiveness. A systematic description of the dermatoscopic features associated with specific body localization is lacking., Objectives: To describe the clinical and dermoscopic features of sclerodermiform basal cell carcinoma (BCC) according to localization in the body confronting with superficial and nodular types., Methods: Clinical and dermoscopic images of sclerodermiform, nodular and superficial BCCs were retrospectively evaluated to study the location in the various body districts, maximum diameter, clinical appearance of the lesion, features of edges and presence or absence of specific dermatoscopic criteria of BCCs., Results: We examined 291 histopathologically proven BCCs showing that in nodular BCCs, classical arborizing vessels were more frequently found in the body macro-area (trunk and limbs; n = 46, 97.9%) than in the head/neck area (n = 43, 82.7%); within sclerodermiform BCCs, short arborizing vessels were found more frequently in the head/neck district (n = 35, 49.3%) than in the body (n = 6, 23.1%; P-value 0.02); within nodular BCCs, multiple blue-grey dots and globules were more frequently found on the trunk (n = 23, 48.9%) than in the head/neck district (n = 12, 23.1%; P-value 0.01). In sclerodermiform BCCs, ulceration was found more frequently in the head/neck district (n = 38, 53.5%) than in the body (n = 4, 15.4%; P-value > 0.01), and in superficial BCCs, ulceration was found more frequently in the head/neck district (n = 5, 38.5%) than in the body (n = 8, 9.8%; P-value 0.02)., Conclusion: Our study shows that superficial BCC are found frequently in the head/neck district dermoscopically characterized by ulceration and arborizing vessels; nodular BCCs are more frequently found in the body than in the head/neck district, and the dermoscopic pattern is characterized by the combination of three features: (i) classical arborizing vessels, (ii) multiple blue-grey dots and (iii) globules. Instead, sclerodermiform BCC is preferentially located in areas at high-moderate risk of recurrence; if pink-white areas and/or fine arborizing vessels are seen, clinicians should consider this diagnosis. Furthermore, location-specific dermatoscopic criteria have been described., (© 2020 European Academy of Dermatology and Venereology.)
