Plain-English summary
A neutered male Russian Blue cat was brought in for a mass on the right side of his nose and swollen lymph nodes in his throat and jaw. After a biopsy, the vet found an inflammatory condition linked to a bacterial infection caused by Pseudomonas aeruginosa. Initially treated with an antibiotic, the cat showed improvement but had a relapse after nine months. The vet then prescribed anti-inflammatory medication and a different antibiotic, which helped manage the symptoms.

Abstract
Case summary An adult male neutered Russian Blue cat presented for a right-sided nasal mass with bilateral retropharyngeal and right mandibular lymphadenomegaly. Medial retropharyngeal lymph node excision with nasal mass biopsy revealed eosinophilic sclerosing lymphadenitis and eosinophilic and lymphoplasmacytic rhinitis, respectively. Bacterial culture of the lymph node grew Pseudomonas aeruginosa, and treatment with pradofloxacin was started. Despite initial improvement, clinical signs recurred after 9 months, and fine-needle aspirates of the right mandibular and left medial retropharyngeal lymph nodes showed eosinophilic and mastocytic infiltration. Bacterial culture of the left medial retropharyngeal lymph node grew P aeruginosa, and treatment with anti-inflammatory doses of prednisolone and, later, marbofloxacin was instituted. Relevance and novel information This report describes a case of feline eosinophilic sclerosing lymphadenitis diagnosed outside of the abdominal cavity and is the first case reported to be associated with P aeruginosa. Feline eosinophilic sclerosing lymphadenitis should be considered as a differential for lymphadenopathy occurring in areas other than the abdominal cavity. Feline eosinophilic sclerosing lymphadenitis may develop in cats due to a species-specific inflammatory response to chronic bacterial and fungal infections.
