Concurrence of Left Maxillary Antrolith and Right-Sided Nasal Inverted Papilloma: Case Report

Antroliths are calcified masses within the maxillary sinus and are detected incidentally on radiological examinations. They occur as a result of the solidification of mucus and nasal debris by mineral salts, calcium, magnesium phosphate and carbonate. The origin of the nidus of calcification may be extrinsic (foreign body in sinus) or intrinsic (stagnant mucus and fungal ball). Inverted papilloma (IP) is the most common benign tumor of the nose and the paranasal sinuses and comprises almost 0.5% to 4% of the primary nasal tumors. Herein, we present a case of a 65-years old woman with complaints of rightsided nasal obstruction, epistaxis, and headache for the last 6 months, report the concurrence of left maxillary antrolith and right-sided nasal inverted papilloma which is the first case report in the literature and discuss the pathophysiologies of these two entities in the light of the literature.
