Primary Angiosarcoma of Breast: a Case Series of Rare Disease

Primary angiosarcoma of breast (PAB) is a very rare disease and it accounts for only 0.05% of all malignant breast tumors. We present the clinical radiological and pathological features, treatment given, and outcome of this rare disease in our institute in a period of 5 years, aiming at contributing to the knowledge of prognostic factors of this rare disease. We report a case of PAB treated at our hospital along with 2 more cases of PAB we found on retrospective analysis. The basic criterion for inclusion in the study was the presence of histopathologically confirmed primary angiosarcoma of the breast: graded into low (G1, G2) and high (G3) grades. Surgeons must be aware about its high systemic metastatic potential, atypical presentation, and diffuse nature of infiltration so that it will be diagnosed early, and undergo a margin negative excision with reconstruction after a proper metastatic evaluation.
