Indian Journal of Pathology & Microbiology. 2004 Apr; 47(2): 217-20http://imsear.searo.who.int/handle/123456789/7547117 references.Malignant breast neoplasms consisting of mixtures of epithelial and mesenchymal elements, are a rarity. Pathogenesis of such diverse elements within obviously infiltrating carcinomas has been the subject of much controversy. After the advent of immunohistochemistry, it is now generally accepted that metaplasia of the epithelial elements of a carcinoma gives these lesions their pseudosarcomatous appearance. Hence the name metaplastic carcinoma is given to malignant breast neoplasms which show Cytokeratin positivity in both epithelial and mesenchymal elements. We recently encountered such a case, which is being presented here along with relevant review of literature.engAdultBreast Neoplasms --metabolismCarcinoma, Ductal, Breast --metabolismFemaleHumansKeratins --metabolismMetaplasiaSarcoma --metabolismMetaplastic carcinoma of the breast--a rare breast tumour.Case Reports
