Case report 672: Gorham's disease
A confusing early "benign" appearance which preceded subsequent radiographic progression of a case of massive osteolysis is presented. Proof of Gorham's disease was obtained by open biopsy of the left femur in this 21-year-old woman who presented with an unusual cortical lesion in the femoral shaft. The lesion initially was subtle in its radiological features but progressed considerably over a 2-year period before biopsy was undertaken.
