[Ashy dermatosis. Review of the literature and report of a case].

The authors make a review of the epidemiologic, etiopathogenic, clinical, laboratory and therapeutic aspects of ashy dermatosis, described in 1957 by Ramírez in El Salvador, of which more than 150 cases have been described up to now in different continents. The disease is exclusively cutaneous, presents peculiar clinical features with a lichenoid tissue reaction, and has no specific treatment or known etiology. The authors report a case in a Brasilian man, followed up for three years. The treatment of a T. trichiura infestation did not change the cutaneous features, as opposed to what has been reported.
