This communication presents the treatment of a clinical case of nasal mucinous adenocarcinoma in a cat.

Clinical case

A 17.5-year-old cat was presented due to nasal discharge from the left nostril. During the rhinoscopy, extended hyperplastic lesions and mucous discharge were noticed in the affected nostril. The presentation was consistent with neoplasia. It was decided to destruct the hyperplastic lesions with the use of Holmium Laser. Postoperatively, amoxicillin/ clavulanic acid and methylprednisolone at an anti-inflammatory dose were administered. A rapid improvement of the clinical signs and cessation of the nasal catarrh within 15 days were noticed. The result of the biopsy showed mucinous adenocarcinoma, the administration of methylprednisolone continued taking place every 48 hours, and toceranib was also added to the treatment plan. The administration of toceranib was ceased after 1.5 months, due to the drug being scarce, and there was a recurrence of the symptoms, along with ascites and metastasis. A palliative destruction of the hyperplastic lesions took place, resulting in cessation of the upper respiratory tract symptoms. After 2 weeks, toceranib was administered again, but without any response.


In our case the results of surgical and systematic treatment against this nasal mucinous adenocarcinoma were, apart from lifetime extension also the improvement of the quality of life of our patient.


Holmium Laser, as a modern surgical instrument, can be considered as a new operative option that can be of assistance to patients.
