[Ashy dermatosis: clinico-pathological associations in two cases].

Case 1. A 54 year old woman affected by chronic asthmatic bronchitis from the age of 11 years and ulcerous recto-colitis from 15 years, presented several erythematous-violaceous macules from the trunk including abdominal region to all skin surface except the face. Case 2. A 17 year old woman presented a similar hyperpigmentation in the same areas. In both patients histology showed a thin epidermis with vacuolar changes of basal layer and apoptotic bodies and melanophages rich in melanosomes in the papillary dermis. Our diagnosis was Ashy dermatitis. Clinico-pathological correlations and treatment options are discussed.
