TROTTE, Marcele Nogueira de Sousa et al. Histopathology of tumor-like masses present in the nasal cavity of equids from Brazil. Cienc. Rural [online]. 2008, vol.38, n.9, pp. 2535-2539. Epub Apr 08, 2008. ISSN 0103-8478. http://dx.doi.org/10.1590/S0103-84782008005000004.
The purpose of the present study was to analyze the microscopic aspects of tumor-like masses present in the nasal cavity of equids and also to emphasize the importance of histopathological examination for determining the diagnosis. Tissue sections of tumor-like masses from the nasal cavity of 11 equids were microscopically examined. These samples were sent to the Anatomic Pathology Service of the Veterinary Medicine College from the Fluminense Federal University, Niterói, Rio de Janeiro, from 2000 to 2004. Three cases of rhinosporidiosis, one of amyloidosis, six of nasal polyps and one of progressive ethmoid hematoma were diagnosed.
