[Kaposiform angiodermatitis (pseudo-Kaposi's disease) on an amputation stump. A new entity]

Kaposiform cutaneous lesions were observed on the amputation stump of a 65-year-old male whose leg had been amputated above the knee. Histological examination revealed pronounced stasis dermatitis. This finding, together with phlebectasias and fine arborized cutaneous varices on the stump end, suggested that the pathogenesis may involve venous congestion. This may be caused by suction in the prosthesis socket and compression of the stump at the socket edge.
