Inverted papilloma of atypical origin with unusual extension into the oropharynx.

Inverted papilloma is a benign tumor with malignant potential that commonly arises from the lateral wall of the nose. We present a case of inverted papilloma, in a premalignant stage, of unusual origin and with oropharyngeal extension. The patient presented with complaints of a nasal mass arising from the left nasal cavity and progressively increasing in size since 2 years. On examination a fleshy, firm, sensitive mass was noted, which was attached to the medial wall, and extending posteriorly and inferiorly into the oropharynx. Diagnostic nasal endoscopy and complete excision of the mass was performed with a stable postoperative period. Histopathology of the mass revealed an inverted nasal papilloma of the septum with carcinoma in situ.
