Orta konkadan kaynaklanan dev anjiyomatözkoanal polip: Olgu sunumu

Choanal polyps (CPs) can be defined as histologically benign, solitary,soft tissue lesions extending towards the junction between the nasal cavity and the nasopharynx through the choana. They usually originate fromthe maxillary sinus. In this report, we present an unusual case of a giantangiomatous CP arising from the inferior part of the middle turbinatethat completely filled the nasopharynx. A 24-year-old man presented withfive-year history of left-sided nasal obstruction, nasal discharge and mildto-moderate epistaxis. The diagnosis was supported by contrastenhanced computed tomography scan of the paranasal sinuses withangiography and confirmed by histopathological examination. The lesionwas removed by combined endoscopic and transoral approach. In addition, we discuss the pathogenesis, clinical, radiological and pathologicalcharacteristics of angiomatous CPs, and their differential diagnosis.
