Rarely Diagnosed Cases of Fibrosarcoma Breast-A Case Series

Breast sarcomas are rare tumors with an incidence of <1% of all breast malignancy [1]. Primary breast sarcomais defined as malignancy originating from mesenchymal tissue of the breast and does not include those arising from skin, muscle, and adjacent bones. They are similar to soft tissue sarcomas elsewhere in the body. Primary fibrosarcoma of the breast is a very rare tumor described in literature, accounting for 16% of all soft tissue sarcomas of the breast (2).Phyllodes tumours of the breast are commonly classified as benign tumours and rarely as borderline or malignant. Cases have been reported where originally benign tumours developed malignant features with recurrences [3]. Primary sarcomas of the breast are extremelyrare and account for less than 0.1% of all malignant tumours of the breast [4], of which the conversion of a phyllodes tumour to sarcoma of the breast is even rarer and only one such case has ever been reported [5].
