[Metaplastic tumors of the breast: a case of primary squamous cell carcinoma].

We report a case of primary squamous cell carcinoma of the breast in a 58 years old woman. The diagnosis of this rare tumor is possible after excluding a skin primary lesion or an epidermoid cancer of a distant site. In reviewing the reported cases we didn't find any significant prognostic difference between this form and the breast adenocarcinoma with squamous metaplasia.
