Canine and Feline Cytopathology: A Color Atlas and Interpretation Guide, 4th Edition provides a comprehensive overview of diagnostic cytopathology for companion animals, covering all body systems and fluids. Rapidly resolve diagnostic challenges with this guide to specimen collection and evaluation, featuring more than 2,400 photomicrographs that show cytology of normal structures to contrast and support identification of cytopathology of inflammatory, hyperplastic, and neoplastic lesions. Enhancements to this edition include hundreds of new images with crisper quality and truer colors; new chapters on the pancreas and ear; updated, contemporaneously referenced information for all chapters; expanded listing for neoplastic and infectious disease testing, quality assurance, and reporting; and access to a fully searchable enhanced eBook with new print purchase. Written by seasoned veterinary cytopathologists and award-winning educators Rose Raskin, Denny Meyer, and Katie Boes, with contributions from 20 international experts, this reference offers clear, practical guidelines to sampling procedures, slide preparation, and interpretation leading to diagnoses and/or classification of the cytopathologic findings. Anticipate the expected and expect the unexpected with this atlas, which vividly illustrates the expected cytologic elements associated with the organ system and provides abundant examples of unexpected cytopathologic findings.
