Enchondroma Wheeless

Description: Discussion: - benign and asymptomatic cartilaginous tumor of bone which most often occurs in adolescents or young adults; - it is an intramedullary cartilage lesion located in central metaphysis; - intramedullary tumor develops in adjacent metaphysis and may eventually penetrates the diaphysis; - results from failure of normal endochondral ossification below growth plate & represents a dysplasia of the central growth plate; - if dysplastic process occurs in lateral growth plate, resulting tumor is called osteochondroma; - dysplastic cartilaginous proliferation beneath the perichondrium results in periosteal chondroma
