  palisaded granulomas
  Definition: Palisading granulomas are a subtype of necrotizing granuloma in which the mononuclear phagocytes at the periphery have elongated or spindle-shaped nuclei that are palisaded and arranged roughly parallel to each other and roughly perpendicular to the edge of the central necrotic zone.
  The most common are rheumatoid nodules and post-surgical necrobiotic granulomas occurring in the prostate, urinary bladder, and other sites.

• salivary mucocele
  4 April 2005

  mucocele; labial mucocele
  Definition: Mucoceles and mucous retention cysts most often involve the minor salivary glands of the lower lip, buccal mucosa, and floor of the mouth.
  Mucoceles lack an epithelial lining and are therefore not true cysts.
  They are thought to result from ductal obstruction or trauma and represent accumulation and extravasation of mucus into adjacent tissues.
