Subacute Necrotizing Sialadenitis: A Series of Three Cases and Literature Review

Subacute necrotizing sialadenitis (SANS) is an unusual inflammatory condition known to primarily affect the minor salivary glands of the palatal region. Patients usually present with a localized, often erythematous palatal swelling accompanied by an abrupt onset of pain. The disease usually resolves between 2 days and a week with few extrapalatal reports lasting longer than 1 week. We report a series of three cases of SANS involving the palate.
