Multiple dark 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).

Multiple dark dots are black/red dots within a well-defined yellowish area are characteristic of plantar warts. Recently, an histopathologic study of 18 palmoplantar warts found no thrombosed vesselsThis glossary term has not yet been described., suggesting that the presence of dark dots is secondary to intracorneal hemorrhages and not to dermal microthrombi (Fried et al., 2018).
