Intraosseous ganglia.

Intraosseous ganglia are benign cystic lesions of the bone; morbid-anatomically, they show no difference from the ganglia that occur in soft parts. The cases of two patients are reported. As far as we have been able to find out these are the first descriptions in the Dutch literature. The clinical aspects, morbid anatomy, pathogenesis and treatment are discussed with reference to the literature.
