Article Synopsis
  • - Necrotising sialometaplasia (NSM) is a non-cancerous growth mostly found in the minor salivary glands, presenting as swelling and potentially ulceration, often mimicking cancer like squamous cell carcinoma.
  • - Histopathologically, NSM is characterized by lobular structures, acinar infarction, and changes in the salivary ducts, with an unknown cause that requires careful distinction from malignant conditions.
  • - The study investigates the role of the TGF-β3 gene, finding that it is upregulated in NSM and may contribute to the condition by inhibiting cell growth and causing cell type changes during healing and tissue regeneration.

Background: Necrotizing sialometaplasia (NSM) is an extremely rare benign lesion with an uncertain pathogenesis. The differential diagnosis of this lesion is challenging due to little familiarity with this entity and histologic similarity with carcinomas, especially mucoepidermoid carcinoma (MEC). The purpose of this study is to raise awareness about NSM, which is often overlooked or misdiagnosed as malignancy in a small biopsy.
