Overview
Chondromas may be classified into two broad types based on their location: enchondromas (tumor grows within the bone and expands it) and ecchondroma (tumor grows outward from the bone).[1]
Classification
- Chondroma may be classified according to the matrix, or substance, that they produce into 4 subtypes:
- Osteoid or bone forming tumors
- Osteoid osteoma
- Osteoblastoma
- Cartilage forming tumors
- Osteochondroma (exostosis)
- Chondroma (enchondroma, periosteal chondroma)
- Chondroblastoma
- Chondromyxoid fibroma
- Fibrous lesions
- Fibrous dysplasia
- Ossifying fibroma (osteofibrous dysplasia)
- Nonossifying fibroma
- Cystic and vascular lesions
- Unicameral bone cyst
- Aneurysmal bone cyst
- Osteoid or bone forming tumors
- There is a less common classification for chondroma based on their anatomic locations:
- Chondroma of tip of the nose
- Extraskeletal chondroma of the scalp
- Intracranial chonrdoma
- Sacrococcygeal chonrdoma
- Skull base chonrdoma
- Spinal chonrdoma
