Irregularly distributed red dotsDots are small, round structures of less than 0.1 mm in diameter that have a red color when corresponding to blood vessels; however, when due to melanin, their color ranges from black, brown, to blue-gray depending on the depth and concentration of the melanin in the skin (Tyndall effect).

Irregularly distributed red dots and yellow crusts/scales are the most common dermoscopic features of dermatitis (allergic/contact dermatitis, atopic dermatitis and seborrheic dermatitisThis glossary term has not yet been described.). 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 vesselsThis glossary term has not yet been described., and yellow crusts/scale, to the epidermal spongiotic reaction (Goncharova et al., 2015; Sgouros et al., 2018).
