Abstract

A 6-year-old spayed female Turkish Angora cat presented with sneezing, nasal discharge, and decreased appetite lasting for 21 days. Skull radiography revealed slightly increased density of soft tissue in the left nasal cavity. Computed tomography (CT) scan revealed an extensive mass with nasal septum destruction and moderate contrast enhancement in the left nasal cavity. After surgical biopsy, histopathological examination confirmed that the mass was an infiltrative round cell neoplasm, composed of sheets of large neoplastic cells. Immunohistochemical analysis revealed that most of the neoplastic cells were strongly positive for CD79a and weakly positive for PAX5. Additionally, numerous mature lymphocytes were found to be positive for CD3. This is the first reported case of nasal diffuse large B-cell lymphoma (DLBCL) in a Turkish Angora cat in Korea.
