Soft tissue fibrosarcoma. A case report and review of the literature.
The soft tissue fibrosarcoma usually presents as an enlarging, painless mass. Pain is usually a result of pressure on surrounding structures. Fibrosarcomas arise from connective tissue and demonstrate no calcification on x-ray studies. These expansile tumors are firm, round or lobulated, and well encapsulated. Their level of malignancy is graded on the basis of various degrees of differentiation of the anaplastic spindle-cells of which they are composed. Treatment generally consists of wide excision or radical local resection. Five-year survival estimates vary from 60 to 90 percent. The lung is the usual site of metastasis. A case of subungual fibrosarcoma of the great toe is presented.
