Edited by two eminent authorities on breast pathology, this heavily illustrated text offers essential guidance on diagnostic evaluation of needle core biopsies. The focus is on the most common and challenging differential diagnostic problems encountered in these specimens. More than 1,100 full-color illustrations depict the entire spectrum of breast pathology seen in needle core biopsies. This edition includes new information on issues in the diagnosis of solid papillary carcinoma; molecular studies of microglandular adenosis; carcinoma with basal phenotype; the e-cadherin immunostain in the diagnosis of lobular carcinoma; use of immunostains to distinguish between papilloma and low-grade papillary carcinoma; and use of myoepithelial immunostains in the diagnosis of microinvasive carcinoma. The book also includes new data on treatment and prognosis. A companion website will offer the fully searchable text and an image bank.
