Inverted papilloma is a rare benign tumor with a high incidence rate in both the nasal cavity and sinuses. The presence of both lesions in the same patient is even rarer. Here we present a case of a male patient with an unusual presentation and dual pathologies of cavernous hemangioma and inverted papilloma of the sinonasal tract that underwent endoscopic surgery and showed no recurrence of disease after a 2\u2010year follow\u2010up. The association of nasal cavernous hemangioma at one side and inverted papilloma at the other side is a very rare occasion that requires further studies and histopathology is the only diagnostic tool.<\/jats:p>","DOI":"10.1002\/ccr3.8366","type":"journal-article","created":{"date-parts":[[2023,12,28]],"date-time":"2023-12-28T11:26:53Z","timestamp":1703762813000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Unusual
