Polyps are benign fleshy growths that originate from the cells lining a cat's nasal passages, leading to a variety of clinical signs such as sneezing, difficulty breathing, and recurrent ear infections. The various diagnostic tools and treatment approaches are explained in this handout.

Nasal tumors are an uncommon type of cancer but when they do occur, they tend to be malignant and locally aggressive. Staging can be done to determine the type of cancer and if it has affected anywhere else in the body. Treatment can be done in some cases to help relieve clinical signs, most often with radiation therapy.

Nasopharyngeal polyps are benign idiopathic masses originating from the middle ear that extend either down the eustachian tube or into the external ear. They can cause stertor, nasal discharge, otitis, otic discharge and head tilt. Diagnosis may involve visualization through otoscopic exam or behind the soft palate, but usually needs radiographic evidence or more advanced imaging such as CT or MRI. Treatment involves debulking the mass through traction which has a high rate of recurrence, or more advanced surgery into the bulla to remove the source of the polyp.

Neomycin ophthalmic is an antimicrobial medication, usually in a combination product, used to treat bacterial infections of the eye. It is used to treat surface eye infections in cats, dogs, and exotic companion animals. Neomycin ophthalmic comes in ointment and liquid drop suspension form. Caution when using this medication in cats, as allergic reactions have been documented.

Neomycin sulfate, dexamethasone, and thiabendazole topical (brand name Tresaderm®) is a combination antimicrobial (neomycin), antifungal (thiabendazole), and steroid (dexamethasone) medication used to treat infections and inflammation of the skin, ears, and anal glands in cats and dogs. It may be used “off label” or “extra label” in other animals and for other conditions. Neomycin sulfate, dexamethasone, and thiabendazole topical comes in ointment form.

Neomycin, isoflupredone, and tetracaine (brand names Neo-Predef with Tetracaine, Tritop), is a combination antibiotic (neomycin), steroid (isoflupredone), and local anesthetic (tetracaine) used in the treatment of certain superficial infections. It is labeled for use in cats, dogs, and horses to treat certain types of skin and ear infections. It may be used"off label" or "extra label" to treat other conditions or in other species.

Neomycin, polymyxin B, bacitracin topical is a combination antimicrobial medication used to treat bacterial infections of the skin. It is used to treat surface skin infections in cats, dogs, and other animals. Neomycin, polymyxin B, bacitracin topical comes in ointment form.

Neomycin/polymyxin B/dexamethasone ophthalmic, also known as neopolydex (brand name Maxitrol), is a combination antimicrobial and steroid anti-inflammatory medication used to treat certain types of bacteria (gram-positive and gram-negative). It is used to treat eye infections and eye inflammation. Neomycin/polymyxin B/dexamethasone ophthalmic comes in liquid eye drop and ointment forms. Avoid use in pets with eye ulcers.

Neuroendocrine tumors are a group of tumors that develop from the cells of the neuroendocrine system, and include insulinomas, gastrinomas, glucagonomas, carcinoids, medullary thyroid carcinomas, small-cell lung carcinomas, pheochromocytomas, chemodectomas, and Merkel cell carcinomas. Some of these tumors are functional, while others are non-functional. The signs of disease in dogs and cats depend on the type of growth, location of the tumor, its size, the degree of infiltration in the surrounding tissues, whether it has metastasized, and whether it is functional. A definitive diagnosis requires tissue biopsy and histopathology, often with histochemical staining and electron microscopy. Staging is highly recommended for these tumors. Treatment may involve surgery, chemotherapy, radiation therapy, and medical and dietary management.
