[Ashy-dermatosis--a case with spontaneous disappearance of the cutaneous lesions]

A 14-years-old girl suddenly developed typical dermal signs of ashy-dermatosis at the time of menarche. After one year, the signs began to fade and had disappeared completely two years later. The direct immunofluorescence and the ultrastructure resemble lichen planus. Endocrine factors may have played a part in the presented case, considering the sudden onset at the time of menarche.
