Necrotizing sialometaplasia associated with bulimia: case report and literature review

Necrotizing sialometaplasia (NSM) is a self-limiting disorder affecting mainly the minor salivary glands. The significance of NSM resides in its clinical and histopathological resemblance to carcinoma. Few cases of NSM associated with eating disorders have been reported to date. We present here the clinical features and histomorphology of an additional case of bulimia-associated NSM closely mimicking an invasive carcinoma. A high index of suspicion and good communication between clinician and pathologist are essential in recognizing this entity and preventing unnecessary surgical therapy.
