Abstract

Abstract

The aim of this study is to highlight the easiest method of investigation (nasal lavage or rhinoscopy) depending on the animal condition. 18 dogs were investigated, which presented at the Faculty of Veterinary Medicine Bucharest, with respiratory distress due to obstruction of the nasal cavities. The sampling for cytological diagnosis was done using the two techniques, the nasal lavage and rhinoscopy. It is most useful to try the lavage first, because it is less invasive, and only then, if case of poor cellularity after centrifugation, or in case of a inflammatory process with unfavourable post-treatment evolution, endoscopy will be used. Cytomorphological diagnosis using, after rhinoscopy or nasal lavage, have evidentiated the following forms of nasal cancer: 10 cases out of 18 were epithelial neoplasms of the olfactory mucosa; 6 cases out of 18 were nerve tumors (malignant melanoma, estesiocarcinoma); 2 cases out of 18 were mesenchymal tumors (osteosarcoma, fibrosarcoma). The nasal lavage is a good sampling method but has the disadvantage of sometimes encountering an acute or chronic inflammatory process that can shield the tumor process.
