Chondroid tumors introduction Chondroid tumors represent the largest group of bone tumors. These can be benign or malignant and sports medicine and orthopedic providers may come across this while reading a radiology report or viewing images. It is important to have some comfort level and background for chondroid lesions or tumors.
Cartilaginous tumors comprise the most common primary neoplasms of bone and as the name suggests they are defined as lesions forming chondroid extracellular matrix. One of the most important aspects when describing these is to differentiate between benign and malignant lesions. Osteochondromas and enchondromas are the two most commonly seen benign lesions.
Chondrosarcomas are the most commonly seen malignant lesions. The World Health Organization (WHO) updated in 2020 the chondroid tumor classification . Some changes were made and chondroblastomas and chondromyxoid fibromas were moved to the benign group.
Synovial chondromatosis was moved to intermediate and was covered in a recent post. The differentiation of enchondromas from atypical cartilaginous tumor/low-grade chondrosarcomas is one of the most difficult distinctions for radiologists, pathologists and clinicians. BENIGN Osteochondroma is a benign cartilage-capped exophytic lesion characterized by a bony stalk containing medullary bone with trabeculae with a continuous marrow space with the underlying affected bone predominantly affecting young patients with open growth plates.
These may also be called exostoses. Osteochondromas are located on the surface of the bones that are formed by endochondral ossification. Most frequently they arise in the metaphyseal regions of the long tubular bones and less frequently on the surface of the flat bones.
If you are experiencing symptoms that may be related to chondroid tumors, it is important to see a sports medicine physician. Early evaluation and treatment typically lead to better outcomes. Do not ignore pain or symptoms that are limiting your activity.
