Benign mixed salivary-type tumour of the breast.

A case of benign mixed salivary-type tumour of the breast is described. This is a rare neoplasm, only 20 cases having been reported to date, characterized by a mixture of epithelial and mesenchymal components, as in similar tumours occurring in the salivary glands and skin. Because this tumour frequently simulates carcinoma clinically, mammographically and histologically, familiarity of both the surgeon and pathologist with this lesion is essential, to avoid the overdiagnosis of malignancy, unfortunately initially made in nearly 50% of previously reported cases.
