Bilateral angiosarcoma of the breast: an overview.

Angiosarcoma of the breast is a rare and aggressively malignant tumour. A case of a young lady presenting with bilateral mammary angiosarcoma and associated pregnancy is reported. Only one such case is documented in the literature. Existing literature is also reviewed. The often deceptively benign histological appearances which are extremely variable demand serious suspicion of angiosarcoma when confronted with an angiomatous lesion of the breast. Early and complete surgical excision is the treatment of choice, and adjuvant chemotherapy may have a role in the treatment. Histological grading is the most important prognostic factor with poor grades having an unfavourable outlook.
