title: Metaplastic carcinomas of the breast (light microscopic and immunohistochemical features).
abstract: Metaplastic carcinomas of the breast are uncommon tumors that contain other cellular components besides the glandular component. These carcinomas have a poor prognosis as compared to breast carcinomas without metaplasia. It is, therefore, important to recognise the metaplastic components. The study was conducted over a three year period. All breast carcinomas received during this period in the department of pathology were analysed for areas of metaplastic carcinomas. The light microscopic features, special stains as well as the immunohistochemical markers of metaplastic carcinomas are highlighted in this paper.
