History

Most cases of necrotizing sialometaplasia appear to arise spontaneously, whereas others are associated with a history of trauma, vomiting, [26, 27] radiation therapy, or surgery. [26] An association with neoplasia, such as parotid tumors, false vocal cord squamous cell carcinoma, and maxillary sinus carcinoma, is also reported. Cases associated with inflammatory conditions such as relapsing polychondritis and acute and chronic sinusitis have been noted to occur in the subglottic and sinus regions, respectively.
