| This study intends to classify and correlate the non-Hodgkin lymphomas according to the cytohistological c1assifications of Rappaport, Kiel, Lukes-Collins and Working Formulation. Results showed that the classification proposed for humans can be applied to dogs, as the non-Hodgkin lymphomas are very similar in both species. Most cases were graded as intermediate (52%), followed by low (28.6%) and high (19.4%) grades. As to the malignancy degree, the lymphomas displayed a single cell type prevalence in each category, with the small lymphocytic cells being the most frequent (17.4%) in low grade lymphomas. In the intermediate and high grade lymphomas, the results indicated diffuse small cleavage cells (22.5%) and immunoblastic type cells (11.2%), as the most... |
