Primary squamous cell carcinoma of the breast is a rare cancer. Published reports of prognosis are variable, and most studies are case reports of one or a few patients. We report an additional case of squamous cell carcinoma of the breast occurring in a 53-year-old black woman. In reviewing the reported cases of this tumor over the past 20 years, we compared features of this cancer with those of the more common breast adenocarcinoma with squamous metaplasia. When squamous cell carcinoma of the breast is encountered, a skin primary lesion and metastasis from a distant site should be excluded. Prognosis is determined largely by stage and does not differ significantly from the prognosis in breast adenocarcinoma with squamous metaplasia.
原发性乳腺鳞状细胞癌是一种罕见的癌症。已发表的关于其预后的报告各不相同，且大多数研究都是关于一两名患者的病例报告。我们报告了另外一例发生在一名53岁黑人女性身上的乳腺鳞状细胞癌。在回顾过去20年报道的该肿瘤病例时，我们将这种癌症的特征与更常见的伴有鳞状化生的乳腺腺癌的特征进行了比较。当遇到乳腺鳞状细胞癌时，应排除皮肤原发性病变和远处转移。预后很大程度上取决于分期，与伴有鳞状化生的乳腺腺癌的预后没有显著差异。
