Usually the diagnosis of AD is performed on the basis of the clinical rash, even if sometimes the characteristic features could be absent in consideration of the stage of the disease. Then in the hypothesis of AD usually also a skin biopsy is necessary to assess the final diagnosis. We report the use of a new tool, recently described, that in our opinion could be helpful in the diagnosis of AD. Dermoscopy is a non invasive exam that can be performed easily also in children. We suppose that the recognition of detailed dermoscopic features could represent a valid diagnostic aid and could allow to avoid a skin biopsy. KEY WORDS: ashy dermatotis; erythema dyschromicum perstans; pediatric dermatology.
