Necrotizing Sialadenometaplasia : Definition , Causes , C/F , D/D , Treatment

Definition Necrotizing sialadenometaplasia is an uncommon, usually self-limiting, benign inflammatory disorder of the salivary glands.

Etiology The cause is uncertain, although the hypothesis of ischemic necrosis after vascular infarction seems acceptable.

Clinical features

  • The lesion has a sudden onset.
  • Clinically characterized by a nodular swelling that leads to a painful craterlike ulcer, 1–5 cmin diameter, with an irregular, ragged border .
  • The lesion mimics a carcinoma, and is usually located on the posterior palate.
  • Men are affected approximately twice as often as women.

Laboratory tests Histopathological examination.

Differential diagnosis

  • Squamous-cell carcinoma,
  • mucoepidermoid carcinoma,
  • adenoid cystic carcinoma,
  • traumatic ulcer,
  • malignant granuloma.

Treatment The lesion usually heals spontaneously within 4–8 weeks.
