Abstract
Carcinosarcoma (CS) also known as metaplastic carcinoma of the breast is a rare and
aggressive type of malignancy with controversial origin. Currently, there are no standard
treatment guidelines outlined, owing to the rarity of the disease, but according to
the available literature, surgery followed by adjuvant radiation therapy has the greatest
benefit. We are presenting two cases of CS of breast developing metastasis. One of
the cases presented with lung metastasis during the course of follow-up and responded
significantly to chemotherapy, and the other is currently receiving chemotherapy.
The cases are being presented here along with the literature review enlightening the
current knowledge and available treatment options.
