METAPLASTIC CARCINOMA OF BREAST : A CASE REPORT

Abstract

Metaplastic breast cancer constitute nearly 1 % of all breast carcinoma cases. There is metaplasia of normal epithelial components of the breast into other types. They are highly aggressive with very poor prognosis. Here we present a case of 30 year old female who presented with a breast lump in her left breast associated with dull aching pain. It was 10 x 10 cm in size involving upper inner, upper outer, lower outer quadrants and retroareolar area of left breast. USG was suugestive of BIRADS VI lesion. Axillary lymph nodes were not found enlarged clinically or radiologically. Core biopsy report showed Phylloides tumor of breast. The patient underwent simple mastectomy of left breast and histopathology revealed spindle cell variant of metaplastic breast cancer. The cell blocks sent for immunohistochemistry were negative for estrogen, progesterone receptors and Her2neu receptor. The post surgical treatment of this type of breast cancer is still under study.
