Fibrous dysplasiaFibrous dysplasia is a benign disorder characterized by tumor-like proliferation of fibro-osseus tissue and can look like anything.FD most commonly presents as a long lesion in a long bone.FD is often purely lytic and takes on ground-glass look as the matrix calcifies.In many cases there is bone expansion and bone deformity.The ipsilateral proximal femur is invariably affected when the pelvis is involved.When FD in the tibia is considered, adamantinoma should be in the differential diagnosis.

Fibrosarcoma is an uncommon, malignant spindle cell neoplasm which can present with different degrees of differentiation. Fibrosarcoma is found most commonly around the knee in the distal femur and proximal tibia followed by the pelvis. It presents in adults age 30 to 60 years old and affects men and women equally. It presents as a painful, localized mass. The radiologic picture of fibrosarcoma is that of an osteolytic lesion.

Malignant fibrous histiocytoma

Adamantinoma is one of the rarest low-grade malignant bone tumours, representing less than 1% of them. Fisher in 1913 named this tumour adamantinoma because of its similarity to ameloblastoma of the jaw. It usually arises in the center of long bones, and 97% of all reported cases were in long tubular bones and mainly in the tibial mid shaft (80-85%). Other long bones not uncommonly affected are the humerus, ulna, femur, fibula and radius. Ribs, spine, metatarsal and carpal bones are very rarely affected. The symptoms are not specific but most frequently the patient complains about swelling, redness, pain and sensitivity of the bone where the tumour is located. Young males are more prone to develop adamantinoma than females. The tumour usually spreads to the lungs, the regional lymph nodes, or other bones.
