Abstract

Primary squamous cell carcinoma of the breast is a very rare tumor accounting for less than 0.1% of all invasive breast carcinomas. It is a particularly interesting entity because it is a very aggressive tumor with negative hormone receptors and is refractory to usual treatment; it has a poor prognosis. We report here a case of primary breast cancer in a 48-year-old woman who presented with a purplish nodule in the left breast fold. Clinical trials including a large series of these rare tumors are needed to deepen our knowledge and improve the currently disappointing results. We report the case of a young 48-year-old patient treated for squamous cell carcinoma of the breast with squamous metaplasia. Through this case, we will review the literature to better define the management of these rare tumors.
