title: [Histogenesis of infantile fibrosarcoma].
abstract: Eight cases of infantile deep soft tissue fibrosarcoma were examined. The tumor consists of neoplastic fibroblasts and myofibroblasts which differ from each other ultrastructurally. Well-differentiated collagen-forming neoplastic fibroblasts form one-half of infantile fibrosarcoma. Immunohistochemically and ultrastructurally immature embryonic-like fibroblasts were also identified. The latter closely resemble an embryonic perichondrial fibroblast of the embryonic limb during 6 weeks of development.
