Abstract:
Growth or radiologic modification of an osteochondroma after the epiphyseal plate closes suggests the diagnosis of malignant transformation to a chondrosarcoma. However, extensive growth of an osteochondroma in a skeletally mature patient whose tumor proved benign has been reported. We report a similar case in an adult who had a solitary osteochondroma of the calcaneus. The lesion showed marked growth and was removed. Histologic examination showed no evidence of malignancy, and there was no recurrence during the 4-year followup.

Changes in the Appendicular Skeleton with Age
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
