<p><i>Atlas for the Diagnosis of Tumors in the Dog and Cat</i> is a diagnostic tool for determining if samples are abnormal and defining the cause of the abnormality.  Providing correlations between cytology and histopathology, the book presents clinical photographs with accompanying photomicrographs showing an aspirate of the lesion and the tissue section, making it easy for the clinician to compare and interpret the aspirate.  Brief summaries of the expected behavior for each tumor cover grading protocols, treatments, and possible outcomes, along with additional tests.</p> <p> </p> <p>With 386 clinical images depicting normal and abnormal results, the book begins by describing specific types of neoplasia.  It then offers clinical pictures of lesions, pictures of needle aspirates, and biopsy photomicrographs of common lesions for each site to aid in diagnosis, organized by anatomic location.  <i>Atlas for the Diagnosis of Tumors in the Dog and Cat</i> is a useful resource for veterinary pathologists, veterinary oncologists, and general practitioners seeking a reference for diagnosing tumors in canine and feline patients.</p> <p> </p> <p><b>Key features</b></p> <ul> <li>Offers a brief overview of the methods used to produce a diagnosis and prognosis from a biopsy tissue sample</li> <li>Pairs photographs of biopsy samples with photomicrographs of cells obtained via fine needle aspirate</li> <li>Includes a useful chapter covering sample handling, staining, and shipping</li> </ul> <p> </p> <p> </p>
