RESUMO

Malignant adipocytic neoplasia is rare among nonhuman primates. We report the gross and microscopic features of a retroperitoneal liposarcoma with myxofibrosarcoma-like dedifferentiation in a free-ranging juvenile golden-headed lion tamarin (Leontopithecus chrysomelas). To our knowledge, this is the first report of such tumor subtype in New World primates.
