In the one case of desmoplastic fibroblastoma of bone, the X-ray of the right proximal femur showed an osteolytic lesion with a well-defined sclerotic rim, but lack of matrix calcification [Figure 1]b.
The schwannoma, also known as neurilemmoma, neurinoma, or perineural fibroblastoma, is a slow-growing benign neoplasm of the peripheral nerves usually located in soft tissues; (1) it is composed of Schwann cells, which is a type of glial cell surrounding the axon of the neurons and forming the myelin sheath, mainly in charge of correctly guide the axon growth.
