Written by a leading expert in thyroid biopsy interpretation, this text/atlas is the most comprehensive reference on thyroid pathology. It contains over 1,700 full-color photomicrographs depicting the full range of findings seen on fine needle aspiration biopsies. The illustrations show the wide spectrum of cytologic features for each disease entity, including unusual as well as typical patterns. Particular attention is given to diagnostic pitfalls, overlapping patterns, and differential diagnosis. The book also includes chapters on basic concepts of cytopathology, fine-needle aspiration biopsy techniques, cytopreparation, ancillary diagnostic techniques, liquid-based cytologic preparations, and the application of needle biopsy findings to management decisions. The fully searchable online text and a full-color image bank are available on a companion Website.
