Solid Tumour Section

Note Enchondroma is usually a solitary benign lesion in intramedullary bone. Usually asymptomatic, it is incidentally discovered as a palpable bony nodule. Rarely, causes soft tissue swelling and pain at the lesion site. Pain can be a sign of pathologic fracture. Both sex are equally affected, and any age group can be involved. It is thought to develop from epiphyseal cartilage rests that subsequently proliferate and slowly enlarge. Approximately 50% of solitary enchondromas are found in the hands, typically in the middle and distal portions of the metacarpals and the proximal portions of the phalanges, 10% in the feet, 20% in the proximal and distal parts of the femur and the proximal part of the humerus.
