Define the underlined terms in each case study. A 9-yr-old MIN toy poodle was scheduled for an excisional biopsy of a skin mass that the owner first observed 2 weeks ago. The surgery went well and the veterinarian sent the biopsy to a pathologist to determine if the mass was malignant or benign. The pathologist prepared a microscope slide and the following is the pathology report: Microscopic Exam: A microscope slide was prepared from a skin biopsy of a mass that was centrally ulcerated The ulcerated area was surrounded by squamous epithelium and exhibited full-thickness dysplasia. The dysplastic change had cells that had hyperchromic nuclei. The lesion does not appear to invade the underlying tissue. Moderate dysplastic changes were seen peripherally and do not extend into the surgical margins. 1. excisional biopsy 2. malignant 3. benign 4. ulcerated 5. squamous epithelium 6. dysplasia 7. hyperchromic 8. lesion 9. peripherally
