title: Cytopathological features of matrix-producing carcinoma of the breast.
abstract: Matrix producing carcinoma (MPC) of the breast is a very rare subtype of metaplastic carcinoma with heterelogous elements, which comprises <0.1% of invasive breast carcinomas. There are very few reports describing the cytological features of MPC. In this article, we aimed to discuss cytological, histopathological and immunohistochemical features of this rare entity in a 59-year-old woman.
