This book provides a detailed update on all aspects of fine-needle aspiration cytology of breast lesions. It will serve readers as an up-to-date reference and atlas on both new entities in breast pathology, including borderline lesions such as flat epithelial atypia, and the classic benign and malignant lesions. Throughout, emphasis is placed on the characteristic diagnostic features as well as the common pitfalls faced by cytologists. As cytologic features can be highly variable, corresponding cytology and histology images are displayed together, enabling readers to gain a good understanding of the morphologic features of various lesions. Core-needle biopsy and fine-needle aspiration cytology are compared in depth, with attention to their relative strengths and weaknesses and indications. In addition, the impact of molecular classification of breast cancers on cytologic diagnosis is explored, and the use of molecular techniques in diagnostic cytology is discussed.
