ABSTRACT

Necrotizing sialometaplasia is a rare condition affecting the palatine minor salivary glands. Clinically, it can be confused with other malignant entities. We present the case of a 40-year-old woman with a history of rheumatoid arthritis who was on Tocilizumab (Actemra) for 10 years. Examination revealed two asymptomatic medial palatal swellings, with a 10-mm ulcer on the left side, with several weeks of evolution. After imaging studies and an incisional biopsy, a diagnosis of necrotizing sialometaplasia was established. This case presentation may help clinicians consider this entity in the differential diagnosis of palatal lesions; it highlights the importance of a good histopathological diagnosis to rule out other entities, preventing radical treatments.
