Correlation of dermatitis
Irregularly distributed red dots
Irregularly distributed red dots and yellow crusts/scales are the most common dermoscopic features of dermatitis (allergic/contact dermatitis, atopic dermatitis and seborrheic dermatitis). Yellow crusts/scales are more frequent in the acute stages of dermatitis (Lallas et al., 2012). Histologically, irregular red dots correspond to slight dilatation of the subpapillary vessels, and yellow crusts/scale, to the epidermal spongiotic reaction (Goncharova et al., 2015; Sgouros et al., 2018).
