sarcoma

[särkō′mə] pl. sarcomas, sarcomata
Etymology: Gk, sarx + oma, tumor
a malignant neoplasm of the soft tissues arising in fibrous, fatty, muscular, synovial, vascular, or neural tissue, usually first manifested as a painless swelling. About 40% of sarcomas occur in the lower extremities, 20% in the upper extremities, 20% in the trunk, and the rest in the head, neck, or retroperineum. The tumor is composed of cells in a connective tissue matrix and may be highly invasive. Trauma probably does not play a role in the cause, but sarcomas may arise in burn or radiation scars. Small tumors may be managed by local excision and postoperative radiotherapy, but bulky sarcomas of the extremities may require amputation followed by irradiation for local control and combination chemotherapy to eliminate small foci or neoplastic cells. See specific sarcomas. sarcomatous, adj.
