[Acroangiodermatitis (pseudo-Kaposi disease)].

We present clinical, angiological, and histopathological findings concerning different kinds of so-called "kaposiform" acroangiodermatitis. In particular, we refer to the etiopathogenesis, prognosis, differential diagnosis, and therapy of each entity. The similarities between the so-called "kaposiform" acroangiodermatitis and Kaposi's sarcoma are primarily derived from clinical criteria. In contrast to Kaposi's sarcoma, the histopathological picture of acroangiodermatitis usually shows stasis dermatitis.
