Frontal recess polyp in a 14-year-old child resembling an antro-choanal polyp

A rare case of a unilateral single nasal polyp arising from a left frontal recess resembling an antro-choanal polyp in a 14-year-old girl is presented. A polypoidal mass completely occupying the left nasal cavity extending to the anterior nares was evident by anterior rhinoscopy. The mass was excised endoscopically, and its origin was found to be the frontal recess of the left nasal cavity, a rare occurrence in the paediatric age group.
