Pharyngeal polyps in two feline siblings

Pharyngeal polyps were diagnosed in 2 sibling kittens referred for evaluation of chronic upper respiratory tract disease. Surgical excision of the masses was performed in both kittens after skull radiography and oral examination. One kitten had a recurrence of pharyngeal polyps 5 weeks after surgery and was euthanatized and necropsied. The clinical and histologic findings in these 2 cases suggested a congenital origin of this disease.
