Enhancing diagnostic precision: a case study on necrotizing sialometaplasia

Necrotizing sialometaplasia (NS) is a rare, benign inflammatory condition of the minor salivary glands that can mimic malignancy, posing a diagnostic challenge. This case report describes a 40-year-old male smoker who presented with a painful ulcer on the palate, initially misdiagnosed as a fungal infection. Clinical examination revealed a 1-cm punched-out palatal lesion near infected upper teeth. Histological analysis of a biopsy confirmed NS, with no malignancy observed. The patient showed significant healing by the 7-week follow-up with no active treatment required. This case underscores the importance of biopsy in differentiating NS from malignancy, especially in high-risk patients. CPD/Clinical Relevance: Correct diagnosis of necrotizing sialometaplasia may be difficult but is needed to ensure appropriate management.
