Acroangiodermatitis is an angioproliferative disease characterized by pseudosarcomatous papules and plaques. It is often associated with different disorders like: chronic venous insufficiency, artero-venous malformations, artero-venous shunts, paralysed limb. In the case of amputation stumps the traumatic and suctional stimula may be the cause of this reactive pathology. We describe a case of acroangiodermatitis in an above-knee amputation stump in a 48-year-old-female affected by Down's syndrome.
