[Metaplastic breast cancer with chondroid differentiation. Report of three cases].
The authors report three cases of breast carcinoma with chondroid metaplasia. These three tumors were characterized by direct transition between the carcinomatous and the mesenchymal component. Immunohistochemical study revealed epithelial antigens within the mesenchymal appearing component. Pitfalls in the diagnosis and in the classification of metaplastic carcinomas are reviewed.
