RESUMO
Angiosarcoma that develops on a limb with chronic lymphedema is called Stewart-Treves syndrome. This typically appears as a complication of a long course lymphedema located on the arm, after mastectomy and/or radiotherapy due to breast cancer. There are cases of Stewart-Treves syndrome in chronic lymphedema in the upper limb contralateral to the breast treated for cancer and in chronic lymphedema of the leg. We present two cases of this syndrome. The first corresponds to a typical syndrome of Stewart-Treves in an 83-year-old woman who was diagnosed of angiosarcoma in a chronic lymphedema territory secondary to mastectomy and radiotherapy due to breast cancer. The second case is much rarer, since it is a case of diffuse angiosarcoma of the leg in a 42-year-old man with a history of lymphedema. Due to the aggressive nature of this syndrome, knowledge and research on its treatment are necessary.

El angiosarcoma que se desarrolla sobre una extremidad con linfedema crónico se denomina síndrome de Stewart-Treves. Éste aparece típicamente como una complicación de un linfedema de larga evolución localizado en el brazo, tras mastectomía y/o radioterapia por un cáncer de mama. Existen casos de síndrome de Stewart-Treves sobre linfedema crónico en la extremidad superior contralateral al cáncer de mama tratado y sobre linfedema crónico de pierna. Presentamos dos casos de este síndrome. El primero corresponde a un típico síndrome de Stewart-Treves en una mujer de 83 años, que fue diagnosticada de angiosarcoma en el territorio de un linfedema crónico secundario a mastectomía y radioterapia por un cáncer de mama. El segundo caso es mucho más raro, ya que se trata de un caso de angiosarcoma difuso de pierna, en un hombre de 42 años e historia de linfedema. La naturaleza agresiva de este síndrome precisa de su conocimiento e investigación de tratamientos para prevenirlo
