We report here 6 cases with classical forms of nonossifying fibroma (NOF)
and 1 case of fibrous cortical defect (FCD) which occurred in the metaphysis of the
long bones of children along with 2 cases of fibrous histiocytoma (FH) which occurred
in the veretebra and femur neck of adults. Their clinical data, radiographs, histopathology,
and ultrasturctural features are described. Through these series, we concluded
that microscopic and ultrastructural findings are not basically different among NOF,
FCD, and FH. NOF is different from FCD in the extent of the disease, the latter involving
only the cortex, which is best evaluated by radiological examination. The FH cases
were located in sites other than the metaphysis of the long bones and were older than
FCD or NOF. Our data concurred with the previous notion that the FCD and NOF(MFD)
are evolutionary forms of the same process. It is believed that certain lesions that we
called fibrous histiocytoma of the bone do exist based on their microscopic similiarities
to fibrous histiocytoma of the soft tissue, although they can be put into NOF or FCD
by the age and site of the involvement.
