Synopsis

Acroangiodermatitis, or pseudo-Kaposi sarcoma, is a benign angioproliferative disorder most frequently arising in the setting of chronic venous insufficiency. Some consider acroangiodermatitis a clinical variant of stasis dermatitis. Other less commonly reported associations include paralysis, amputation, congenital or acquired arteriovenous malformations, and thrombotic syndromes.

Stewart-Bluefarb syndrome refers to acroangiodermatitis arising in the setting of congenital arteriovenous malformations, typically on the lower extremities. The condition is often diagnosed in teenagers or young adults.

The pathophysiology of acroangiodermatitis remains unclear. Some studies suggest that increased production of vasogenic growth factors, following disruption of normal cutaneous vascular perfusion, may play a role.
