Case report: two cases of extremely rare primary pure squamous cell carcinoma of the breast

摘要

Rationale:Since primary pure squamous cell carcinoma of the breast is a rare disease, few reports describe the characteristic findings on performing preoperative imaging that can be used to distinguish it from normal breast cancer. The rapid evolution and lack of an established method of treatment has resulted in several reports of advanced cases of primary pure squamous cell carcinoma of the breast.
