[Attrition of the mandibular bone caused by compression of the submandibular salivary gland. Description of a case].

A case of circumscribed reabsorption of the internal osseous lamina of the horizontal branch of the mandible, caused by compression of the submandibular salivary gland, is described. The picture, which recalled that of solitary bone cyst, is explained by reference to the fact that the mandible is of connective origin, and allows itself to be imprinted relatively easily by surrounding, adjacent anatomical formations during growth. In case of this kind, no treatment is required.
