Feline nasopharyngeal polyps (FNPs) are benign, nonneoplastic, pedunculated masses
that arise from the mucosa of the nasopharynx, auditory (Eustachian) tube, or middle
ear and may extend into the nasopharynx, tympanic cavity, or both [
[1]
]. A relatively uncommon disease, synonyms for these masses include feline inflammatory
polyps, pharyngeal polyps, aural polyps, middle ear polyps, feline respiratory tract
polyps, and otopharyngeal polyps [

]. FNPs are most often found in young cats, although they can occur in middle-aged
or older cats. These polyps are the most common mass of the feline external ear canal
and are the second most common cause of nasopharyngeal disease after lymphoma [

]. Similar polyps have been reported in the horse and dog [

], and aural-pharyngeal polyps have been reported in iguanas [
[8]
]. A histologically similar mass has been described in the trachea of a cat [
