Description
Book SynopsisPractical Veterinary Dermatopathology explains the when, why, where and how of biopsy collection and submission of samples. With plenty of quick reference tables, high quality illustrations, and case review studies, as well as over140 illustrations, the material is accessible for students, veterinarians, and technicians. Techniques for collecting and handling biopsy samples are clearly depicted along with recommendations for the biopsy technique that is most suitable for the specific clinical lesion and/or its anatomic location. The case review studies show how to manage the biopsy sampling process, formulate clinical differential diagnoses, and interpret pathology reports.
