Giant Dysplastic Sinonasal Inverted Papilloma

Sinonasal Inverted Papilloma is known for its malignant change, recurrence, and local aggressiveness. Though the long-practised method of treatment is extensive local excision of the tumor, recent trends are changing towards endoscopic approaches. Our aim in presenting this case report is to add on to the literature regarding the ease of the endoscopic approach in managing an extensive IP where complete clearance was possible contradicting the older notion of requiring an extensive and radical open approach for complete clearance. We also aim to discuss the diagnostic challenge faced and management options in the diagnosis of IP when histopathology shows dysplastic changes.
