Special stains and immunohistochemistry were performed on poorly differentiated cases. Ninety-two percent (113\/123) of the tumours were malignant. There was an increased risk for old cats (mean age of 10.9 years), and a male predilection (59% males). Clinical signs and breeds varied with the histological type of tumour. Thirty-nine percent (48\/123) of the cases presented with nasal discharge, 21% (26\/123) with dyspnea, 20% (24\/123) with facial swelling, and 15% (19\/123) with epistaxis. Forty-three percent (53\/123) of the tumours were of epithelial origin. Adenocarcinomas (18\/53) and squamous cell carcinomas (17\/53) were the most common epithelial tumours. Fifty percent (26\/53) of the epithelial tumours originated from the pseudo-stratified respiratory epithelium of the nasal cavity, 28% (15\/53) from the stratified squamous epithelium of the vestibule, 9% (5\/53) from olfactory epithelium, 9% (5\/53) from submucosal glands and 4% (2\/53) from minor salivary glands. Malignant lymphoma (35\/123) was the most common tumour. Seventy-one percent (25\/35) of the malignant lymphomas were B-cell tumours and 29% (10\/35) were T-cell tumours. Six cases of malignant lymphomas were proved to be epitheliotropic T-cell lymphomas. This is the first report of a primary nasal epitheliotropic T-cell lymphoma in cats.<\/jats:p>","DOI":"10.1053\/jfms.2001.0141","type":"journal-article","created":{"date-parts":[[2002,9,19]],"date-time":"2002-09-19T09:56:27Z","timestamp":1032429387000},"page":"235-245","source":"Crossref","is-referenced-by-count":91,"title":["Feline
