| Summary: | Fibrosarcoma of bone is a relatively rare malignant neoplasia, representing less than 5% of all bone tumors. It is distinguished from other bone sarcomas by the presence of spindle-shaped tumor cells located among intertwining bundles of collagen fibers, without any other type of histological differentiation, such as the formation of cartilage or bone.
In the present report, we present a rare case of primary fibrosarcoma in the distal femur in a 45-year-old patient with complaints of mild pain and swelling in the right knee joint for approximately 6 months. After imaging evaluation, a biopsy was performed; in the second stage, a subsequent resection of 16 cm of the distal femur and its replacement with a tumor endoprosthesis was performed. Three months postoperatively, no local recurrence or metastasis of the tumor was observed.
