Recently we experienced three cases of tumors or tumorous conditions in the femoral neck of children.
Case 1. A boy, 13 years old, was treated with resection and autogenous bone graft. The histological diagnosis was nonossifying fibroma. The course was satisfactory.
Case 2. A girl, 7 years old, was treated with homogenous and autogenous bone graft. The histological diagnosis was solitary bone cyst. The course was satisfactory.
Case 3. A girl, 11 years old, She had already sustained the pathologic transcervical fracture and was treated with curettage, accurate reduction, bone grafting and internal fixation. But the femoral head was followed by aseptic necrosis. The histological diagnosis was granulation surrounding the necrotic bone tissue. Therefore the pathologic diagnosis couldn't be established.
