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, t
hese conditions are often misdiagnosed and therefore mistreated. A rev
iew of the literature and a classification of all types of acro-angiod
ermatitis are presented. We also describe a case of a patient with acr
o-angiodermatitis which completely regressed following a course of dap
sone combined with leg elevation and elastic support stockings.
