CD44s as a surrogate marker for distinguishing intraductal papilloma from papillary carcinoma of the breast.

BACKGROUND It has been shown that CD44 variants are differentially expressed in normal and neoplastic breast tissues. The diagnostic value of these markers in distinguishing benign from malignant breast lesions has not been well examined.

Poroid hidradenoma becomes malignant in less than 1% of cases, but its histologic characterist...
