BACKGROUND Although the diagnosis of chondrosarcoma, especially the distinction between enchondroma and low-grade chondrosarcoma or low-grade chondrosarcoma and high-grade chondrosarcoma, is pathologically difficult, differential diagnosis is very important because the treatment strategies for these diseases are completely different. The grading system is crucial in predicting biologic behavior...

#{149} Be familiar with the radiologic manifestations that allow differentiation of the majority of enchondromas and intramedullary chondrosarcomas affecting the appendicular skeleton. Distinction of enchondroma versus intramedullary chondrosarcoma a!fecting the appendicular skeleton (proximal to the metacarpals and metatarsals) is a frequent diagnostic dilemma. The authors studied a large seri...

A 27 year old man presented with two bony lumps in the fifth toe of the right foot. Both lumps were present from early childhood. The lump in the toe was painful while both lumps were bony and the lump in the metatarsal was diagnosed to be an exostosis of the bone while the phalangeal lump was diagnosed to be an enchondroma. It is a known association to have multiple exostosis with diaphyseal b...

Giant cell reparative granuloma (GCRG) is a rare, benign intra osseous lytic lesion occurring especially in gnathis bone but also seen in feet and hands. It has similar clinical and radiological presentations than giant cell tumor, chondroblastoma, aneurysmal bone cyst, and hyperparathyroidism brown tumors but with specific histological findings We report a case of a GCRG of hallux phalanx in 1...

About 90% of the hand bone tumors are enchondromas. Treatment of choice is complete curettage and bone grafting, usually with bone autografts. We present a case of finger enchondroma in a 27-year-old female patient who was treated with curettage and synthetic bone grafting. Clinical, surgical and pathological findings in this case are presented along with a brief discussion of literature.

Enchondromas are the most common benign cartilaginous bone tumors arising in the medullary cavity of the small bones of the hand. In contrast, chondrosarcomas, commonly occurring in the pelvis and proximal femur and humerus, are very uncommon at this site. We report an unusual case of chondrosarcoma arising in the ring finger proximal phalanx with its radiological and histological features and ...

Less than 10% of chondrosarcomas occur in children. In addition, as little as 0.5% of low-grade chondrosarcomas arise secondarily from benign chondroid lesions. The presence of focal pain is often used to crudely distinguish a chondrosarcoma (which is usually managed with wide surgical excision), from a benign chondroid lesion (which can be followed by clinical exams and imaging surveillance). ...
