Schneiderian papilloma is also called sino-nasal papilloma. It is a harmless epithelial neoplasm and happens in the sinonasal tract. 

According to the World Health Organization, there are three categories of Schneiderian papilloma-

  • Inverted papilloma

  • Oncocytic papilloma

Its association with the Human Papilloma Virus is both high risk and low risk. The architectural pattern is inverted (endophytic). The nature of the epithelial lining is squamous, transitional or respiratory. It has very little possibility of transforming into a malignant papilloma (nearly 5-15%)

It has a low-risk association with HPV. Its architectural pattern is exophytic (filiform). And its epithelial lining is squamous, transitional or respiratory. It has no possibility of becoming malignant.

A person is likely to contract it in his/her 50s or 60s. It has no association with HPV. The architectural is exophytic or endophytic. Its epithelial lining is oncocytic. It has a 4-17% risk of turning malignant.
