Overview
Enhondromas arise from rests of growth plate cartilage or chondrocytes that are normally involved in the production and maintainence of the cartilaginous matrix, which consists mainly of collagen and proteoglycans.[1][2] Juxta-cortical chondromas (also known as periosteal chondromas) arise from the periosteum of tubular bones.[3] On microscopic histopathological analysis, avascular lobules of hyaline cartilagenous matrix interspersed with chondrocytes, separated by normal marrow are characteristic findings of chondromas.[4][5] On gross pathology, small (usually less than 3 cm), translucent, grey blue, nodular lesions with occasional calcifications are characteristic findings of chondromas.[6]
Pathophysiology
- Enchondromas arise from rests of growth plate cartilage or chondrocytes that are normally involved in the production and maintainence of the cartilaginous matrix, which consists mainly of collagen and proteoglycans.[7][8]
- Juxta-cortical chondromas (also known as periosteal chondromas) arise from the periosteum of tubular bones .[9]
- On microscopic histopathological analysis, avascular lobules of hyaline cartilagenous matrix interspersed with chondrocytes, separated by normal marrow are characteristic findings of chondromas. The fibrous capsule may be used in differentiating it from the malignant chondrosarcoma.[4][5]
- On gross pathology, small (usually less than 3 cm), translucent, grey blue, nodular lesions with occasional calcifications are characteristic findings of chondromas.[10][11]
