Cutaneous angiosarcoma of the leg

Abstract

Angiosarcomas are malignant neoplasms arising from endothelial cells. Cutaneous angiosarcoma is the most common form, typically occurring in the setting of chronic lymphedema or previous radiation. The head and neck are the most common locations for cutaneous angiosarcoma, with rare occurrence on the trunk and extremities. Herein, we present a case of angiosarcoma on the lower extremity in an elderly man. This 71-year-old man presented with a two-year history of red-yellow discoloration of the left lower leg with subsequent development of black nodules over the past several months prior to presentation. He denied any itching, bleeding, or ulceration. Past medical history included diabetes, hypertension, and non-melanoma skin cancer. Physical examination showed erythematous, violaceous, non-blanchable papules with yellow atrophic regions and overlying black crusted nodules and plaques. Biopsies were taken and the patient was diagnosed with angiosarcoma and referred to a tertiary care center for further evaluation.
