Acro-angiodermatitis: review of the literature and report of a case.

Acro-angiodermatitis is a very common disorder, with a close clinical, anatomical and morphological resemblance to Kaposi's sarcoma. Several types of this disorder can be found in different settings. However, these conditions are often misdiagnosed and therefore mistreated. A review of the literature and a classification of all types of acro-angiodermatitis are presented. We also describe a case of a patient with acro-angiodermatitis which completely regressed following a course of dapsone combined with leg elevation and elastic support stockings.
