INTRODUCTION: Breast cancer is the first cancer in women and clearly constitutes a real public health problem. Although adenocarcinoma remains by far the most common histologic type, there are other types that vary in frequency. A particular form which is the squamous cell carcinoma holds our attention. MATERIALS AND METHODS: The clinical records of patient consultants at the Joliot Curie Institute in Dakar between January 1, 2016 and June 30, 2020 were reviewed. We have retained the cases of pure or mixed breast squamous cell carcinomas. RESULTS: Our study focused on three observations received and treated at the Joliot Curie Institute in Dakar. These patients were 48, 50 and 48 years old respectively. They did not have any particular medical history. They were all postmenopausal. They had consulted following a self-palpation of a breast nodule. The biopsy had concluded in a mammary squamous cell carcinoma. Two of the three patients were metastatic. CONCLUSION: At the end of our study, we recommend a larger scale study including several centers. The therapeutic sequences must be better evaluated and compared to the most frequent form, which is infiltrating ductal adenocarcinoma.
