Abstract: A case of necrotizing sialometaplasia (NS) is presented in a female patient, who initially presented as a suspected head and neck malignancy. This relatively rare condition holds diagnostic importance because of its ambiguous clinical and histopathological presentation that can be misdiagnosed clinically as neoplasia. The aim is to add to the existing literature on this condition with a rare collection of fully illustrative clinical images and the aetiology and pathogenesis of NS based on an up-to-date literature search will also be discussed. There are no conflicts of interest. The natural history of necrotizing sialometaplasia, a benign inflammatory condition is presented, with rarely seen clinical photographs from inception to fully developed lesions through to healing stages. Ultrasound and MRI images that characterize the acute phase of this condition are also presented.

Clinical relevance: The implications of patients’ use of smartphone cameras to document their condition is discussed, which can be of immense help to the clinician.
