Monomorphic 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). Monomorphic and symmetrically distributed red dots over an erythematous background together with white scaling are the hallmark pattern of psoriasis. Histologically, they correspond to the presence of spiraled capillaries in the papillary dermis and psoriasiform epidermal hyperplasia and parakeratosis (Sgouros et al., 2018).
