An unusual giant subacute necrotizing sialadenitis as an emergency case of otolaryngology.

Subacute necrotizing sialadenitis is an inflammatory necrotizing lesion occurring in minor salivary glands. Most cases occur in the palatal region. In this article, we reported a 36-year-old man referred to our clinic as an emergency with the complaints of excessive bleeding, airway obstruction and hipovolemia. Intraorally, there was a hemorrhagic, protruding giant mass in the palatal region. Following the first biopsy, which was not diagnostic, a second biopsy was performed. Histopathologic examination showed acinar cell necrosis and dense inflammation of the affected minor salivary glands in the second biopsy. The diagnosis of subacute necrotizing sialadenitis was made on the basis of clinical and histologic features of the lesion. Subacute necrotizing sialadenitis is a rare lesion, and admittance to the otolaryngology clinic as an emergency case is much rarer. To avoid unnecessary surgical intervention, it is necessary to diagnose subacute necrotizing sialadenitis correctly, which can be confused with malignant diseases of the salivary glands.
