The histopathologic study of the piece revealed a fusocellular neoplasm constituted by a population of cells of fibrohistiocytic appearance with pleomorphic oval nuclei and fusiform cytoplasm, which alternated with cells of epithelioid appearance. This type usually is low-grade, with areas of histiocito,a and hemosiderin deposits, together with a pleomorphic fibrohistiocytic population and high mitotic activity.

They were arrayed forming imbricated bundles and adopting a storiform growth pattern in areas, which confirmed the initial diagnosis. Sometimes amputation may be necessary to remove the whole lesion.
