Giant sarcomatoid carcinoma of the breast - a rare case report.

Metaplastic breast carcinoma breast is rare entity having mixture of epithelial and mesenchymal elements which contains overtly sarcoma-like elements on light microscopy and its clinical behaviour is not well documented. We are presenting a case in a 50 - year old female presented with a large swelling over the left side of the breast. On histopathology, diagnosis made as metaplastic carcinoma of the breast with sarcomatoid variant. The case merits presentation because of its rarity, low frequency of axillary metastasis and difficulty in interpreting the morphological features which correspond with prognosis.
