OP - BILATERAL REPORT OF NECROTIZING SIALOMETAPLASIA

Necrotizing sialometaplasia is a benign, self-limiting, and rare inflammatory disease of the minor salivary glands. The exact etiology is unknown; however, many authors suggest that ischemic changes could lead to the salivary gland infarction followed by necrosis. This study aimed to report an atypical case of a bilateral sialometaplasia on hard palate. A 53-year-old woman, heavy smoker, reporting daily alcohol consumption with bilateral palatal painful lesions with three days of development, which on the third day became into two deep ulcerations. The edges of the lesions were flat and soft, and the base revealed an exposed bone. No radiographic changes were observed. An incisional biopsy was performed and the histopathological findings were coagulation necrosis, inflammation, and squamous metaplasia consistent with necrotizing sialometaplasia. The ulcers resolved after topical desoxyribonuclease fibrinolysin treatment within 8 weeks. The importance of this case is to report an atypical clinical aspect.
