Skin ulcers in a patient afflicted with microscopic polyangiitis.

Systemic vasculitis is a group of heterogeneous diseases characterized by inflammation and blood vessel walls necrosis. Usually the skin is one of the first organs involved, especially with damage of small to medium size vessels. The cutaneous patterns may help clinicians to diagnose these diseases at the beginning of their course, preventing complications due to internal organ involvement. The following case presents a patient with a microscopic polyangiitis that started with several skin ulcerations localized on the inferior limbs.

The use of elastocompressive therapy in a patient with acroangiodermatitis of the lower limb.

 Acroangiodermatitis is a rare vasoproliferative disorder, usually affecting the lower limbs and is associated with congenital or acquired vascular conditions. There are two variants of acroangiodermatitis-Mali type (associated with venous hypertension) and Stewart-Bluefarb type, which is associated with arteriovenous malformation, or acquired iatrogenic arteriovenous fistula in patients with chronic renal failure. Acroangiodermatitis is clinically characterized by angiomatous papules and plaques, which mimics Kaposi's sarcoma. The authors present a case of a 63-year-old man with acroangiodermatitis of the lower limbs and chronic venous insufficiency who was treated with elastocompressive therapy.
