Plain-English summary
A 13-year-old female Domestic Shorthair cat had been suffering from a persistent runny nose with thick discharge on one side for 18 months. After imaging tests, a mass was found in her nasal cavity and sinus. Unfortunately, the cat was euthanized, and a postmortem exam revealed that the mass was a type of tumor made up of abnormal plasma cells. Additionally, she had a secondary infection in her nose and sinuses. This case highlights the importance of considering this type of tumor when diagnosing upper respiratory issues in cats.

Abstract
A 13-year-old female spayed Domestic Shorthair cat presented with a history of right-sided mucopurulent nasal discharge for 18 months. Computed tomography revealed a mass within the right nasal cavity and the right frontal sinus. The animal was euthanized, and a postmortem examination was performed. On macroscopic examination, the right nasal cavity and the right frontal sinus were partially occluded by a soft whitish mass. Microscopically, the mass was composed of well-differentiated plasma cells that were immunopositive for immunoglobulin G and lambda light chains. These findings were consistent with a mature-type sinonasal plasmacytoma. In addition, there was right-sided mucopurulent rhinitis and sinusitis caused by a Pasteurella infection, which probably developed secondary to the sinonasal plasmacytoma. To the authors' knowledge, this is the first report of a sinonasal plasmacytoma in a cat. The present communication shows that feline sinonasal plasmacytomas should be included in the differential diagnosis for tumors located in the upper respiratory tract of cats.
