Malignant fibrous bone histiocytoma

Malignant fibrous bone histiocytoma is a tumor of a high degree of malignancy, the frequency is not determined. The main constituent elements of the tumor are histiocyte-like cells and spindle-shaped fibroblasts present in various ratios.

ICD-10 code

• C40. Malignant neoplasm of bones and articular cartilage of extremities.
• C41. Malignant neoplasm of bones and articular cartilages of other and unspecified sites.

Symptoms

The clinical picture of ZFH is similar to that of osseogenic sarcoma. X-ray differential diagnostics has a certain meaning in the presence of a lytic form of the bone tumor, since such a picture can not be with a malignant fibrous histiocytoma.

Diagnosis and treatment

The principles of diagnosis and the treatment program for UFH bone coincide with those for osseogenic sarcoma.

Forecast

The prognosis with ZFH of the bone is somewhat worse than in the case of an osgeogenic sarcoma, however, there are no exact figures on this score.
