Metaplastic carcinoma of the breast

This is a retrospective study of 4 cases of metaplastic carcinoma collected at the anatomy pathology laboratory of Mohamed Taher Maamouri University Hospital of Nabeul, between January 2016 and February 2018. Our study illustrates the heterogeneity and specificity of metaplastic carcinoma of the breast clinically and pathologically. This variability means that this type of tumor remains poorly understood and its management unsuitable. Further studies are needed to better understand the molecular features of this tumour in order to adapt its management and improve its prognosis, which is considered more negative than that of the classic non-specific type of breast carcinoma.
