Abstract: Low grade central osteosarcoma is a rare primary bone tumor. This fibro-osseous lesion shares some radiological and histopathological resemblance with fibrous dysplasia, which is a more common entity. Thus it may be mistaken as fibrous dysplasia and may receive inadequate treatment resulting in a more malignant recurrent bone tumor. We present a case of low grade central osteosarcoma of the right tibia, which was initially treated as fibrous dysplasia with curettage and bone grafting. Three years later the tumor recurred with greater soft tissue and bony involvement but without metastasis. The patient was treated with above knee amputation and has been asymptomatic for the last two years. [Copyright &y& Elsevier]

Abstract: Desmoplastic fibroma of bone is an extremely rare locally aggressive primary bone tumour. Diagnosis is tricky and treatment experience limited with tumor surgeons. We studied three rare cases of desmoplastic fibroma arising primarily in bone at unusual sites. Diagnosis was established by radio-histopathologic correlation. Patients were operated with various modalities. Results were evaluated over long term follow-up (6–9years). The disease was eradicated in all the three cases and no recurrence was seen over long term follow-up. Functional outcome was good and no complications were encountered. Wide resection of the tumor is favoured as the recurrence rates after surgical treatment are high. [Copyright &y& Elsevier]
