Abstract:
A 26-year-old man with a history of chronic primary lymphedema of the left lower extremity presented with elephantiasis, confluent, violaceous, mascerated plaques, and ulcers on the dorsal aspects of the toes of the left foot. Histopathologic examination showed a proliferation of small blood vessels associated with extravasated erythrocytes and hemosiderin deposits consistent with the diagnosis of acroangiodermatitis. Treatment of the focal ulcers includes compression therapy, local wound care, and surgical elimination of the shunt if there is an associated arteriovenous malformation.
