2. In any case of dyschondroplasia in which an increase in the size of an exostosis takes place after growth of the skeleton is complete, it is strongly suggestive of malignant degeneration at that point.
3. Dyschondroplasia has a world-wide distribution and in the East it shows the identical characteristics that it does in the West.
