“…Califano, et al, through their molecular genetics investigation, showed that ISP was a true neoplasm arising from single progenitor cells [ 4 ]. There are two hypotheses proposed for the origin of ISP - metaplastic inversion of the surface epithelium or metaplasia of surface epithelium and ductal epithelium [ 3 ]. Although benign, ISPs are often locally aggressive.…”

Inverted sinonasal papilloma (ISP) is a benign epithelial neoplasm arising from the Schneiderian membrane. We report a case of ISP in a 50-year-old male that clinically presented as a polypoid mass in the nasal cavity. Imaging studies revealed it to be an aggressive lesion showing intracranial extension. On histopathological examination of the excised specimen, a diagnosis of ISP was arrived at. However, an extensive sampling of the tissue revealed no evidence of any malignant transformation. Taking into account the suggested viral aetiology for such lesions and the aggressiveness observed in this case, human papillomavirus (HPV) profiling was done but it turned out to be negative. Only one other case of inverted sinonasal papilloma arising from the nasal cavity and involving the brain has been reported in the literature to date. Considering the alarming clinical course in spite of its benign nature, it is important for the pathologist and surgeon to be well informed about this lesion.

Inverted papilloma is a benign epithelial growth arising from the underlying stroma of the nasal cavity and paranasal sinuses. The pathogenesis of this lesion uptil date remains unclear. The tumor is known for its local invasiveness, rapid recurrence and link with malignancy. The recurrence rate of this tumor is usually too high that represents residual disease in most of the cases. Hence, it is mandate that the patient keeps a proper follow up on long term concerns. Here is one such patient, whose nasal mass seemed Antrochoanal polyp clinically but ended up as Inverted papilloma histopathologically.
