Postirradiation angiosarcoma of the breast--a case report.

Angiosarcoma of the breast is an uncommon neoplasm but coincident angiosarcoma with infiltrating ductal carcinoma is not yet reported. This paper describes a case of angiosarcoma which developed after 4 years of a wide excision and adjuvant radiotherapy for a ductal carcinoma of the breast. Due to latent period of only 4 years radiotherapy cannot be blamed as an aetiological factor in this case but neither is it possible to exclude it as a causative factor.
