title: [Histochemical and electronic microscopical studies of stellate fibrillar formations (SFF) in salivary gland tumors].
abstract: OBJECTIVE
  To study the structure and significance of SFF in pleomorphic adenoma and myoepithelioma.
  
  
  METHODS
  Tow cases of each tumor were studied. Histologie and ultrathin sections were made, stained with HE, Mallory, Van Gieson, Pollak methods, and examined with light and transmission electronic microscopes. RESULTE: The SFF were proved to be formed by radial arrangement of collagen fibers, which were composed of striped fibrillae under TEM.
  
  
  CONCLUSIONS
  The structure of the SFF is understood, their existence may play a role the pathologic diagnosis.
