Two Cases of Necrotizing Sialometaplasia of the Soft Palate

Necrotizing sialometaplasia was defined by Abrams et al. in 1973 as a reactive necrotizing inflammatory pro-cess involving minor salivary glands. Prior to recognition of necrotizing sialometaplasia as a benign, self-limited lesion, it was all too often diagnosed as either squamous cell carcinoma or mucoepidermoid carcinoma and had been improperly treated because of its clinical and histological resemblance to malignancy. We report two cases of necrotizing sialometaplasia. One case involved a 56-year-old female who developed a necrotizing sialometa-plasia in association with palato-pharyngeal flap wound after excision of soft palate cancer and reconstruction. Another case involved a 55-year-old male who had a soft palate mass.
