抄録

Necrotizing sialometaplasia is a benign lesion affecting the minor salivary glands of the hard palate. This lesion may be clinically and histopathologically confused with malignant lesions. A case of a 47-year-old man who presented with necrotizing sialometaplasia on the left side of the hard palate is herein reported. A biopsy was performed, and the condition was diagnosed based on immunohistochemistry. The lesion receded following treatment with tranexamic acid and sodium azulene sulfonate. The symptom of painful swelling on the hard palate subsided within 10 days. The palatal lesion had disappeared completely 4 months later.
