SÍNDROME DE STEWART-TREVES – UMA COMPLICAÇÃO RARA DE UM ACHADO FREQUENTE

Stewart-Treves syndrome is a rare entity with bad prognosis. It has been described as a lymphangiosarcoma in lymphedema context. We present the case of a 79-year-old female patient with a history of left breast invasive ductal carcinoma 10 years ago, treated with mastectomy and axillary lymph node dissection, chemotherapy and radiotherapy. She was observed in the Dermatology department for cutaneous changes in her left arm with two months of evolution, which didn’t improve with antibiotherapy. At the physical examination, we observed a high-grade lymphedema with erythematous-violaceous nodules on the anterior inner face of the left arm. A biopsy was performed and the diagnosis of angiosarcoma was established. The patient died one month after by disease’s progression. The awareness of the dermatologic semiology of this entity could lead to an early detection, with a precocious intervention and a better prognosis.
