Abstract
Breast sarcomatoid carcinoma, which are malignant tumors that form from the mesenchymal tissue of the mammary gland, are extremely uncommon and come in two varieties: primary and secondary (development associated to therapy). Breast sarcomas are malignancies that are aggressive and have a bad prognosis. Multidisciplinary surgery, chemotherapy, and radiotherapy are among the treatment possibilities. This case report reports a case of 35-year-old female presented to our hospital with a palpable tumor in her right breast and pungent discharge from her nipples. These signs persisted for over five years. A sarcomatoid breast cancer was discovered by postoperative histology.
