[Inclusions of salivary gland tissue in the mandible, various locations, pathogenesis]

In connection with three cases of their own, the authors recall the radiological signs of this entity isolated by Stafne in 1942. They demonstrate that this picture of the mandibular angle or of the premolar area is quite characteristic and suggestive and usually makes diagnosis possible. They show that the inclusion is always of normal salivary glands corresponding to the gland opposite the cavity: sub-maxillary for the angle, sublingual for the premolar area. They prefer the pathogenetic theory that it is an error in development during embryogenesis of the pelvi-lingual sulcus and of sub-maxillary and sublingual gland formation.
