Abstract

Necrotizing sialometaplasia is an uncommon salivary gland disease originally described by Abrams et al in 1973. The disease may occur wherever salivary gland tissue is found. Theories on the etiology of this disorder have been advanced, but never definitely determined. Treatment consists of adequate biopsy and observation until healing occurs at six to eight weeks. While the disease is considered benign, its similarity to more aggressive neoplasms can be both disturbing and misleading to the patient and the clinician. Such a case of necrotizing sialometaplasia of the nasopharynx is presented to demonstrate the clinical and histological similarity of this disease to carcinoma. In this case, the patient first presented with a neck mass which could easily have been mistaken for a regional metastasis. The current literature is reviewed.
