Ashen dermatosis (D.C.), or dyschromic perstans erythema, is a chronic dermatosis, which is asymptomatic and practically exclusive in Latin-American countries. Its clinical characteristics have been well defined (blue-gray patches), as well as its nonspecific histopathologic patterns; its etiology is unknown. This paper studies 20 patients suffering from ashen dermatitis. There was a majority of female patients, the dermatosis was disseminated, bilateral and symmetric. It is different from pigmented lichen although the histopathologic patterns is similar.
