Acroangiodermatitis (Pseudo-Kaposi sarcoma)

Acroangiodermatitis or Pseudo-Kaposi sarcoma is a rare angioproliferative entity, related to chronic venous insufficiency or certain other vascular anomalies. It is often associated with chronic venous insufficiency, arteriovenous malformation of the legs, chronic renal failure treated with dialysis, paralyzed legs and amputation stumps. We hereby describe a case of 45 year old female presenting with pitting pedal edema, multiple ulcers over bilateral lower limbs with irregular margins with erythema and hyperpigmentation of the surrounding skin. Color Doppler study of bilateral lower limbs was normal. Histopathological examination from one of the lesions showed hyperplastic epidermis, proliferation of capillaries in dermis, hemosiderin deposits and lymphocytic infiltrate. These features thus confirmed the diagnosis of Acroangiodermatitis
