title: A variant of fibrous dysplasia (osteofibrous dysplasia).
abstract: We are reporting the cases of five patients with a tumor-like lesion that has recently been called osteofibrous dysplasia but has also been called osteogenic fibroma, monostotic cortical fibrous dysplasia, and a variant of fibrous dysplasia. The lesions in our patients developed in childhood and were located in the diaphysis of the tibia, which was bowed anteriorly. The structural stability of the limb was not affected. In four patients the lesion recurred after a biopsy and curettage was performed in childhood. No further surgical procedure was done until the patients reached skeletal maturity. The lesion in one patient was biopsied at the age of twenty-one years. No subsequent treatment was recommended.
