Fibrosarcoma (Subscribe)  

Fibrosarcoma is a malignant fibroblastic tumor characterized by interlacing bundles of collagen fibers. This sarcoma may occur in various soft tissues, as well as, in bone. In the past 40 years diagnostic criteria have been established to better define its pathological characteristics. At one time all highly cellular, collagen-forming spindle...

Fibrosarcoma is a tumor of mesenchymal cell origin that is composed of malignant fibroblasts in a collagen background. It can occur as a soft-tissue mass or as a primary or secondary bone tumor. Fibrosarcoma was diagnosed much more frequently in the past; it is now more reliably distinguished histologically from...

Discussion: - fibrosarcoma of bone occurs most often in adolescents or young adults; - presents in major long bones, presenting as painful mass; - preoperative staging studies are needed to differentiate low grade ...

Taconis WK, van Rijssel TG. A study was made of the clinical course of 102 cases of fibrosarcoma of long bones. Of these, 55 were predominantly fibroblastic or pure fibrosarcomata while 47 contained extensive areas resembling so-called malignant fibrous histiocytoma (MFH). Treatment was similar...

Discussion: - an invasive, malignant, spindle cell tumor which demonstrates cellular atypia, mitosis, & formation of type I collagen; - it is less aggressive in soft tissue than in bone; - most...

Fibrosarcomata and malignant fibrous histiocytomata arising in relation to enchondromata.Sanerkin NG, Woods CG. Six cases are reported in which a fibrosarcoma or malignant fibrous histiocytoma developed in relation to an enchondroma in a long bone. Four of the tumours were fibrosarcomata, and two were...

This is a rare soft tissue sarcoma which predominately occurs on acral sites. These tumors vary in size from a few centimeters to almost 20 centimeters. They typically occur on hands and feet, usually around the ankles or wrists. They are slow growing and painless. Treatment usually is complete excision....
