This book reviews the current applications of molecular tools in cytopathology and provides a concise handbook for those who provide care in this era of personalized medicine. Specifically, the text offers a comprehensive and concise review of the emerging molecular tests available clinically in different subspecialties of diagnostic pathology. It examines the current data on molecular testing already applied in cytopathology, discusses some of the biomarkers with potential utility in cytopathology in the near future, and reviews the technical challenges in applying and validating molecular tools in liquid-based cytologic materials. Molecular Cytopathology will serve as a valuable resource for cytopathologists, cytotechnologists, pathology trainees, and clinicians with an interest in molecular applications in cytopathology.
