Necrotizing sialometaplasia is an ulcerating, self-limiting inflammatory lesion of the salivary gland. The most common site of occurrence is reported to be the minor salivary glands of the hard palate. It is often misdiagnosed clinically and histopathologically, as malignant lesions such as a squamous cell carcinoma or a mucoepidermoid carcinoma. A case of this disease, occurred after an intra-oral anesthesia, was reported.<BR>A 29-year-old Japanese man noted a painless ulcer and swelling of his hard palate after an infiltrating anesthesia for pulpectomy of the left maxillary second premolar. An excisional biopsy of the lesion revealed a picture of necrotizing sialometaplasia. The lesion healed completely 6 weeks after the biopsy and no evidence of recurrence was noted.
