Intravascular papillary endothelial hyperplasia (Masson’s tumor) is a rare non-neoplastic vascular proliferative process in a normal blood vessel or vascular malformation. Nose and paranasal sinuses are extremely rare location for this type of tumor. We report a case of Masson’s tumor in a 33-year-old female, presented with an obstructing nasal mass in the right side, repeated epistaxis and rhinorrhea for eight months associated with anosmia, frontal headache and proptosis.
