Pleomorphic adenoma of the breast

Abstract

A clinicopathologic study of a pleomorphic adenoma of the breast is presented and attention is drawn to a previously unreported association with a cyst. Malignancy was strongly suspected in the light of radiologic features. Immunohistochemistry stresses the similarity between pleomorphic adenoma of salivary gland and breast. A common histogenesis of the two entities is also suggested. Ontogenetic links of both glands are mentioned.
