[Atypical presentation of a polyp of Killian].

The antrochoanal polyp or polyp of Killian is a benign nasal tumour that arises from the maxillary sinus. The polyp originating from the middle turbinate is an entity rarely described in the literature. We report here a rare case of Killian polyp originating from the middle turbinate which was explored by computed tomography and magnetic resonance imaging of the facial bone. The polyp was removed by an endoscopic surgical technique. The extraction was made from the oropharynx. Preoperative recognition of these anatomical variations is particularly important to avoid intraoperative surprises.
