Nasopharyngeal angiofibroma presenting as adult osteomalacia: case report and review of the literature.
Unexplained osteomalacia may be the result of various neoplasma including ENT tumors. The mechanism of this oncogenic osteomalacia is uncertain, but it may result from a tumor-induced alteration in vitamin-D metabolism or from a direct phosphaturic action of a tumor product. Thorough ENT evaluation of patients presenting with unexplained osteomalacia is indicated, as successful tumor excision can lead to cure.
