Acute necrotising sialometaplasia

Acute necrotising sialometaplasia

This usually occurs on the palate and primarily a ff ects the minor salivary glands. It initially presents as a swelling that goes on to develop a central crater with rolled out margins, mimicking a malignant ulcer. Clinically it can be mistaken for a malignancy and the biopsy also raises doubt because of the presence of necrosis and hyperplasia. However, the lobular architecture of the glands is generally preserved and the lack of cellular atypia might help the pathologist to reach the right diagnosis. Ultimately , the lesion heals in a few weeks. The exact aetiology is unknown but is suspected to follow trauma or be caused by an injection to that area or by excessive vomiting.
