Abstract
Squamous cell carcinoma of the breast is a rare metaplastic breast tumor whose histogenesis is controversial. Its prevalence is estimated between 0.06 % and 0.2 % of all breast neoplasms. The histogenesis remains obscure. The clinical aspects are not specific. Squamous cell carcinoma is characterized by a rapid evolution and by an uncodified treatment. The objective of our work, by reporting a new case of primary squamous cell carcinoma of the breast, is to specify through a literature review some characteristics of this particular form of breast cancer. Squamous cell carcinoma of the breast is a rare tumor belonging to the heterogeneous group of metaplastic carcinomas. The clinical and radiological presentations are not specific. The prognosis.
