thanks a lot drprasu.

maheshwari says that adamantinoma is common in 10-35 yrs age grp.and fibrous dysplasia in 20-30 yrs.
is this correct?
this info does not fit in many qns.

both are common in same age gr.(codt says around 2nd and 3rd dec.) so this is not really a differentiating feature

according to emedicine

adamantinoma is after age 20 years

and fibrous dysplasia two third are after 10 years
and can be seen after 20years also.
