title: [Idiopathic eruptive macular pigmentation (author's transl)].
abstract: The feeling of the authors is that their seven reported cases of a pigmented dermatosis are different from the ashy dermatosis and from the erythema dyschromicum perstans. This disease, which affects children and teenagers, males as well as females, is characterized by pigmented macules 5-25 mm in diameter, affecting the neck, the trunk and the limbs. The first symptom is whether a pigmented spot, or an erythematous, papular or achromic lesion; in the latter instance the pigmentation occurs only secundarily. In most of the cases this dermatose is slowly and spontaneously regressive. The histological picture is not really specific. In one case there was a marked intraepidermal dyskeratosis of the sweat duct openings. The etiology remains unknown.
