Concurrent Nasal Adenocarcinoma and Rhinosporidiosis in a Cat
2010
Brenseke, Bonnie M. | Saunders, Geoffrey K.
A 10-year-old, neutered, male Domestic Shorthair cat was presented to the teaching hospital for labored breathing, anorexia, and weight loss of several months duration. External examination revealed distortion of the bridge of the nose and pink fleshy polyps protruding from each nostril. The cat was euthanized and submitted for postmortem examination. In addition to the external findings, the nasal cavity had extensive bone and cartilage loss and contained a tan firm mass in the caudal region of the nasal cavity near the cribriform plate. On histologic examination, the mass was a nasal adenocarcinoma, and the polyps were composed of hyperplastic nasal epithelium and submucosal stroma that contained sporangia consistent with Rhinosporidium seeberi.
