Benign mixed tumor (pleomorphic adenoma) of the breast: ultrastructural study and review of the literature.
A patient is presented with a benign mixed tumor (pleomorphic adenoma) of the breast. There are 11 well-documented cases of this rare breast neoplasm. It is histologically and ultrastructurally identical to that seen in the salivary gland and follows a similar benign course. A central role of the ductal myoepithelial cell is proposed for the histogenesis of this tumor.
