Signalment: 3yr old spayed female Domestic Shorthaired cat Clinical history: The patient was presented for an evaluation of three years history of dermal nodules appearing on the margins of the ear pinnae. One year after appearance, nodules appeared on the nasal planum, and nasal congestion was also reported. On presentation, Cryptococcus antigen test was performed and resulted negative. Bacterial culture of the nasal passages was collected via rhinoscopy under anesthesia and grew Pasteurella spp. Nasal passages biopsy showed moderated numbers of mixed inflammatory cells including lymphocytes, plasma cells, neutrophils and scattered eosinophils. A specific infectious etiology or malignant neoplastic process is not identified. On dermatological examination there were multiple crusted nodules/mass affecting the margins of the left ear pinna. The nasal planum was ulcerated and swollen with loss of the normal architecture. The nasal passages were also stenotic due to the swelling. Similar lesions were present on the tip and the base of the tail. Skin cytology showed numerous cocci and a pyogranulomatous inflammation. |
