A case of necrotizing sialomataplasia: consideration on cause, bone change, and incidence / 대한구강악안면방사선학회지

ABSTRACT

Necrotizing sialometaplasia (NS) is a rare, benign, self-limiting lesion, but it mimics carcinoma both clinically and histologically. Authors present a case of NS on the right posterior hard palate in a 16-year-old boy. This case showed underlying erosive bone change on CT images. We supposed this lesion resulted from the local anesthesia for dental treatment. Presented NS is the only one case from approximately 1, 500 oral and maxillofacial biopsies (0.07%) at Chonnam National University Hospital during the period from 1999 to 2004.
