  • Rare in cat.

  • Usually involves the sublingual and/or mandibular ducts.
  • Treatment: surgery generally curative.
  • Prognosis: good.

Pathogenesis

Etiology

Predisposing factors

General

Pathophysiology

  • Trauma/bites/neoplasia/idiopathic/iatrogenic   →   leakage of saliva into surrounding tissue.
  • Salivary gland or duct becomes damaged.
  • Saliva leaks out and takes path of least resistance.
  • Saliva irritates tissue and causes inflammation initially.
  • Granulation tissue forms the lining of the mucocele, preventing further migration of saliva.
