The authors report a case of chondroblastoma which was localised in the distal femoral epiphysis in a 16-year-old boy. The lesion was large, rapidly expanding and extended into the knee joint. After diagnostic evaluation including tru-cut biopsy, the lesion was treated surgically with curettage and grafting with coralline hydroxyapatite. Four months after surgery the patient had no pain and had...

Chondroblastoma (CB) is a rare benign tumour (<1% of all bone tumours) involving epiphyseal long bones (male:female 1.5:1). During development, and in the postnatal period, IHh/PTHrP and FGF signalling molecules control the space and timing of chondrocyte differentiation. Considering the close relationship of CB with the growth plate (age and location), the expression of proteins involved in ep...

BACKGROUND Chondroblastomas are rare epiphyseal bone tumors. Very few cases with extra-cortical aggressive soft tissue invasion or metastasis are reported. CASE PRESENTATION We report a 28 year-old adult male who presented with a large swelling over the left shoulder region. Pre-operative imaging revealed a large tumor arising from upper end of humerus with extensive soft tissue involvement n...

Introduction Myxoid chondrosarcoma is a distinct subtype of chondrosarcoma with several key differences from conventional chondrosarcoma of bone. Our review of the literature and have found that myxoid chondrosarcoma is typically extra skeletal in presentation. Very few cases of myxoid chondrosarcoma of the hand or wrist have been reported and they were extra skeletal in presentation [1-10]. We...
