title: [Erythema cinitiensis perstans].
abstract: The authors report a case of Erythema Cinitiensis Perstans, in a thirty-one years old white man. This dermatosis, reported in the literature also es Ashy Dermatitis and Erythema Dyschromicum Perstans, is here in Brazil exceptional. Clinically this dermatosis is characterized by the presence of gray patches in a sometimes surrounded by an erythematous active border. The lesions may occur on any area of the integument, sparing the hair scalp, palms, soles and nails. The therapy has been ineffective in all the cases, but one reported by Stevenson and Miura and in our case, where the patients have improved after Dithiazanine iodide treatment due to intestinal parasitoses by the Tricocephalus trichiurus.
