What is endosteal scalloping?
Endosteal scalloping refers to the focal resorption of the inner layer of the cortex (i.e. the endosteum) of bones, most typically long bones, due to slow-growing medullary lesions 1.

Can enchondroma disappear?
An unusual feature of the syndrome is the tendency for the tumors to regress and actually disappear in adulthood (87–89). The enchondromas are found in the metaphyses of long bones and in the iliac crest, which is an unusual location for the tumors in enchondromatosis and Maffucci syndrome (Figure 159-4).
