FIBROHISTIOCYTIC TUMORS
A group of heterogeneous soft tissue tumors, many of which probably have little in common, is traditionally included under this heading. The term โfibrohistiocyticโ is essentially descriptive and refers to a light microscopic morphological resemblance of tumor cells to fibroblasts and histiocytes; it does not appear to have any relationship to line of differentiation or histogenesis. However, the term is retained in this chapter due to its widespread general use and because most tumors in this category are of uncertain histogenesis.
