Description
Summary:Necrotizing sialometaplasia (NS) is a rare benign disease characterized by a reactionary inflammatory process of salivary glands, which may mimic malignancy, creating diagnostic dilemma leading to unwarranted aggressive treatment. On the present report, a 51-year-old male patient without comorbidities who was a casual alcoholic and smoker for over 25 years sought care with complaint of a painful wound on the palate for 15 days. Intraoral examination revealed an ulcerated wound localized in the transition between hard and soft palate, measuring 2.5 cm, and rounded with friable necrotic tissue and well delimitated elevated borders. The initial diagnostic hypothesis was squamous cell carcinoma. Incisional biopsy was performed, and the histopathologic analysis revealed mixed inflammatory process, ulcerated, involving minor salivary glands with focus of squamous metaplasia. The final diagnosis was NS. The treatment was the quitting of smoking and monitoring of the case. After 60 days, there was regression of the wound compatible with cure.
