Primary squamous cell carcinoma of the breast.

We discuss a case of a female in her 60s diagnosed with primary squamous cell carcinoma of the breast. It is an aggressive and rapidly growing breast cancer with limited cases discussed in the literature. The female underwent a simple mastectomy and sentinel lymph node biopsy and received adjuvant chemotherapy. This is an exceedingly rare and interesting case and required management involving a medical oncologist specialising in skin, and the reason for reporting this case is to share the pathway and events during the diagnosis and management of this rare cancer.
