The cytologic method of pathology is now one of the most widely used diagnostic modalities worldwide. This new and practical text in cytopathology is an organ-based guide for professionals in which malignant and benign tumors are the predominant focus, but the full spectrum of infectious and inflammatory disorders will also be presented in detail, and in both adult and pediatric populations. Coverage is not limited to findings from only the light microscope but also includes many examples of other genetic, molecular, and immunologic diagnostic modalities, giving pathologists diagnostic and clinical criteria needed when formulating a diagnosis and differential diagnosis. This book is illustrated with more than 2000 full color photomicrographs and accompanied by a CD-ROM of all images in a downloadable format. Differential Diagnosis in Cytopathology proves to be the most comprehensive text in a market in which no other has focused exclusively on essential diagnostic criteria.
