Case report of necrotizing sialometaplasia

Abstract
Introduction: Necrotizing sialometaplasia is a rare inflammatory necrotizing reactive process that can involve minor and major salivary glands. Gland tissue ischaemia has been proposed as the aetiology. Case Report: A 21-year-old woman was referred with a 1-week history of bilateral painful swelling of the palate, with the development of two deep ulcers after the first 3 days. Ulcer edges were elevated but not indurated, and the bases had a necrotic appearance. An incisional biopsy of the margin of one ulcer confirmed the diagnosis of necrotizing sialometaplasia. The ulcers spontaneously healed within 8 weeks without treatment. Discussion: The clinical and histological similarity between this entity and a malignant lesion implies a risk of unnecessary or inadequate treatment. This case illustrates the need for an incisional biopsy to be analyzed by an experienced pathologist to establish a correct diagnosis. © Medicina Oral S. L.
