• 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.

  Macrophages exist in almost all animals. In some invertebrates, mesenchymal cells, endothelial cells or fibroblast-like cells can transform into macrophages.
  In vertebrates, primitive macrophages first develop in yolk sac hematopoiesis and differentiate into fetal macrophages. Monocytes are differentiated from hematopoietic stem cells in the late stage of fetal (...)
