title: Rhinoliths causing palatal perforation: case report and literature review.
abstract: Rhinoliths are calcified masses formed within the nasal cavity because of the solidification of mucus, debris, or foreign objects by gradual accretion of mineral salts. They are mostly asymptomatic and incidentally diagnosed, although some patients may complain of nasal discharge and obstruction. Ulceration of the nasal mucosa, facial swelling, and bone destruction are less frequently observed but bring about difficulties for differential diagnoses with several pathologic entities. This article presents a case of a 54-year-old woman with a rhinolith causing palatal perforation, focusing on the diagnostic process and histopathologic characteristics.
