Recurrent Primary Angiosarcoma of the Breast Presenting as Kasabach-Merritt Syndrome: A Case Report and Review of Literature.

Angiosarcoma of the breast is an unusual tumour. The diagnosis of this condition is difficult clinically, pathologically and radiologically. Treatment includes surgery followed by chemoradiation. The tumour is notorious for its recurrence and is generally associated with poor prognosis. Kasabach-Merritt syndrome also is a very rare entity seen primarily in infants with vascular malformations and carries a poor prognosis. In this report, the authors describe a patient with recurrent primary angiosarcoma of the breast, which presented as Kasabach-Merritt syndrome.
