“…Four dots in a square are thought to be an optical artifact resulting from the interaction between polarized light and keratin-filled adnexal openings and are observed commonly in SCC and actinic keratosis but also reported in association with melanoma, BCC and other inflammatory conditions. [22][23][24] This structure has not been reported before in BSC and it was present in 11.1% of all BSC in our study.…”

Basosquamous carcinoma (BSC) is a rare skin cancer which has areas of basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) and a transition zone between them. However, dermoscopic features of BSC are not well described in the published work, except one study. The aim of the present study was to better identify and clarify the dermoscopic findings of BSC in the largest group of patients in the published work and to describe its dermoscopic features according to histopathologically BCC-dominant, SCC-dominant and intermediate categories. Dermoscopic features of 36 histopathologically proven BSC and their dermatopathological correlates were retrospectively analyzed. Dermoscopic features were evaluated by pattern analysis. Keratin mass (91.7%) was the most common dermoscopic feature. Surface scaling (77.8%), ulceration (69.4%), white structureless areas (69.4%), white clods (66.7%) and blood spots on keratin mass (66.7%) were the other frequent findings. Polymorphous vascular pattern consisting of various combinations of branched, serpentine, straight, coiled or looped vessels were detected in 61% of the lesions. BSC has BCC-dominant vascular features together with otherwise SCC-dominant morphology, the common pattern seen in BSC lesions being BCC-dominant polymorphous or monomorphous vasculature, together with dermoscopic findings of keratinization. White circles, known to be a valuable clue to SCC and keratoacanthoma, were present at the same magnitude in BSC in our study. The observed histological correlation of eosinophilic keratin overlying the epithelium which lined follicular infundibulae in these tumors, provides a plausible new perspective on dermoscopic white circles.

“…Our findings specifically highlight its usefulness for discriminating sBCC from BD on lower extremities. 17 There are some limitations of the current study that should be stated. First, the retrospective design is subject to recall and observation biases, which were addressed by involving three independent evaluators blinded to the clinical and histopathologic diagnosis.…”

“…6,8,10 White shiny streaks in combination with white shiny areas, which are seen only in polarized dermoscopy mode as orthogonal short and thick lines, 15 are commonly present in BCC and represent dermal fibrosis. 16,17 The algorithms based on pattern analysis proposed by Kittler et al describe the dermoscopic features of BCC with different nonmetaphorical terms, such as blue, grey clods, radial brown or white lines, and branched or thin serpentine vessels 18 (Table 3). Bluegrey dots, ulceration and structureless areas are used synonymously in both nomenclatures.…”

Dermoscopy of basal cell carcinoma

2018

View full text Add to dashboard Cite

Dermoscopy is widely used in dermatological practice. The method increases the accuracy of basal cell carcinoma (BCC) detection. Pigmented and nonpigmented variants of basal cell carcinoma present different dermoscopic features. Specific dermoscopy criteria have been recognized in different subtypes of BCC. Differentiation of superficial BCC from other subtypes is the most important issue, as it may determine further management decisions.
