Abstract

Breast malignancy comprises malignant tumors originating from epithelial tissue and breast sarcoma arising from mesodermal tissues. Despite heterogeneity in tumors, most malignant tumors of the breast are composed of a single type of tumor. Here, we report a patient with breast tumor consisting of three different types of malignancies-squamous cell carcinoma, invasive ductal carcinoma, and high-grade breast sarcoma.

Keywords: breast malignant tumor; breast sarcoma; invasive ductal carcinoma; squamous cell carcinoma.

(B) The red arrow shows a nodule in the upper lobe of the right lung, indicating lung metastasis. (C) The red arrow shows another nodule in the upper lobe of the right lung, suggesting lung metastasis. (D) The red arrow shows abnormal bone density on the thoracic third vertebral body (T3), indicating bone metastasis.
