Pathogenesis (development of disease)
An enchondroma originates from cartilage tissue. It consists of mature chondrocytes (cartilage cells) and has a hyaline matrix typical of cartilage, which is characterized by high pressure elasticity. The chondrocytes are benign (benign) in nature. Due to growth, an enchondroma thins the cortical bone (outer layer of bone) from the inside and leads to recognizable distensions (easily visible as local swellings from the outside). Characteristic are spatter-like calcifications (“popcorn-like”) and a lack of cancellous structure. Usually, the diameter of an enchondroma is less than 3 cm.
An enchondroma is thought to be embryonic remnants of the epiphyseal groove (growth plate).
Etiology (Causes)
The exact causes of an enchondroma are still unclear.
