Pseudo-Kaposi's sarcoma: the association of arterio-venous malformations with skin lesions resembling Kaposi's sarcoma.

A patient is described with skin lesions resembling Kaposi's sarcoma (KS). Arteriography revealed multiple arteriovenous malformations in the affected limb. This condition has been termed pseudo-Kaposi's sarcoma. Although reports of this condition have appeared in dermatological journals, as yet we are unaware of any account in the radiological literature. This paper presents a case and reviews the literature. In suspected cases of KS in which the history or clinical features are atypical, this unusual condition should be considered and a search made for the diagnostic vascular lesions.
