title: Angiosarcoma of skin and soft tissue: a study of forty-four cases.
abstract: Forty-four cases of skin and soft tissue angiosarcoma seen at M. D. Anderson Hospital before 1976 were reviewed. The cases fell into six different clinical groups: scalp-face, 17 cases; postmastectomy, 14 cases; postradiation, 5 cases; leg with vascular stasis, 2 cases; breast, 2 cases; and miscellaneous, 4 cases. In all cases in the first four groups, the tumors involved primarily the dermis and subcutis and showed similar blends of vasoformative and solid histologic patterns. Two tumors in the miscellaneous group closely resembled those in the larger groups, but the other two in that group (both located in deeper soft tissue sites) and the two breast angiosarcomas had a somewhat different microscopic appearance. Survival was generally poor in all groups, owing to frequent local recurrence and early metastasis; median survival for the entire series was 20 months. Findings of significantly favorable prognostic importance were tumor size less than 5 cm (in the scalp-face group) and a moderate or marked lymphoid infiltrate in and around the tumor. Less significant favorable factors were a distal location ( in the postmastectomy group) and a low degree of pleomorphism. Only nine patients had long-term, disease-free survival.
