Metastatic calcification of the nasal septum presenting as an intraoral mass: a case report with a review of the literature.
Review
Overview
abstract
Metastatic calcification is a pathologic condition characterized by deposition of calcified product in otherwise normal tissues as a result of hyperphosphatemia with or without concurrent hypercalcemia. Metastatic calcification presenting clinically as an oral lesion is extremely rare. To date, only 7 cases of metastatic calcification involving the oral soft tissues have been described. This report describes a case of metastatic calcification of the nasal septum presenting as a mass of the anterior maxillary vestibule in a patient with end-stage renal disease. The case reported is only the second example with nasal septum involvement. A brief review of the clinical and histopathologic features of previously reported intraoral cases is also presented.
