It is quite rare in our environment. We report a case of Oncocytic Schneiderian papilloma arising from the right maxillary sinus and extending to the ipsilateral nasal region in a 26year old Nigerian male. The growth was present for a period of 5 months before his presentation on 18-10-2005 and recurred again nine months later after excision. Both excised tissues were confirmed by histology to be Oncocytic Schneiderian papilloma, with no evidence of malignancy after a rigorous search.<\/jats:p>","DOI":"10.4103\/1596-3519.55672","type":"journal-article","created":{"date-parts":[[2009,11,6]],"date-time":"2009-11-06T06:37:34Z","timestamp":1257489454000},"page":"91-93","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":4,"title":["Oncocytic Schneiderian Papilloma Occurring in a Young Nigerian Male: A Case Report"],"prefix":"10.4103","volume":"7","author":[{"given":"D.","family":"Olusina","sequence":"first","affiliation":[{"name":"Department of Anatomic Pathology, University of Nigeria Teaching Hospital, Enugu, Nigeria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.
