A practical guide for the diagnostic surgical pathologist, this book presents the diverse spectrum of pathologic alterations that occur in the breast in a manner analogous to the way they are encountered in daily practice. Lesions are grouped according to their histologic patterns to simulate the way pathologists face these lesions as they examine microscopic slides. The approach is based on pattern recognition and emphasizes differential diagnosis. The book contains over 500 full-color photomicrographs and 50 tables summarizing key clinical and pathologic features and differential diagnostic issues. A companion Website will offer 900 full-color images, plus the fully searchable text and a test bank that is ideal for board preparation.
