Final answer:
The three primary benign tumors that appear cartilaginous are enchondroma, osteochondroma, and chondroblastoma. These tumors arise from cartilage tissue and are most commonly found in the medullary cavity, near the growth plate of long bones, and in the epiphysis, respectively.
Step-by-step explanation:
Three primary benign tumors that appear cartilaginous are:
- Enchondroma
- Osteochondroma
- Chondroblastoma
Enchondromas are common cartilaginous tumors that can occur within the medullary cavity of a bone. Osteochondromas are characterized by an overgrowth of cartilage and bone and are often found near the growth plate within long bones. Chondroblastomas are rare, benign bone tumors that usually occur in the epiphysis of long bones.
The three main types of cartilage tissue mentioned in the reference, hyaline cartilage, fibrocartilage, and elastic cartilage, are involved in the normal development of the skeleton and cartilaginous structures, including the thyroid cartilage of the larynx, and are responsible for endochondral ossification, which forms structures like ribs and sternum.
