title: Angiosarcoma of the breast following segmental mastectomy complicated by lymphedema.
abstract: A patient is discussed who had angiosarcoma of her lymphedematous right breast develop four years after segmental mastectomy for infiltrating ductal carcinoma. The lymphedema developed and persisted after an indolent and recurrent postoperative infection. The possibility that the second malignancy is a consequence of the chronic lymphedema, similar to the angiosarcomas of lymphedematous extremities after radical mastectomy, is cautiously entertained. This hypothesis is worthy of consideration as more breast conservation surgery is being done, with or without adjuvant radiation therapy, and accumulating evidence suggests that lymphedema of the breast is a common complication of surgery followed by radiation.
