Primary Malignant Fibrous Histiocytoma of Breast: A Common Tumour in an Uncommon Location

This report concerns a case of primary de-novo origin malignant fibrous histiocytoma of breast in a 32 years young lady involving almost the entire right breast. Fine needle aspiration cytology of the breast mass suggested a malignant spindle cell lesion. Then she was treated by simple mastectomy followed by chest wall irradiation. Histopathology together with immunohistochemistry confirmed the lesion as malignant fibrous histiocytoma, a rare de-novo origin breast neoplasm. Her post operative period was uneventful except radiation induced brachial plexopathy.
