Which of the following conditions can be associated with Chondrosarcoma?

• A. Rickets
• B. Ollier disease
• C. Paget's disease
• D. Osteogenesis imperfecta

Answer: (B)

Chondrosarcoma is a type of cancer that arises in cartilage-forming cells. Ollier disease, which is characterized by multiple enchondromas (benign cartilaginous tumors), is indeed associated with an increased risk of developing chondrosarcoma. The presence of multiple enchondromas can lead to malignant transformation over time, which is why individuals with Ollier disease need to be monitored closely for any signs of malignant change.

The other conditions listed do not have a direct link to the development of chondrosarcoma. Rickets is a condition caused by vitamin D deficiency, leading to weakened bones but does not inherently promote cartilage tumors. Paget's disease involves abnormal bone remodeling but is more associated with osteosarcoma than chondrosarcoma. Osteogenesis imperfecta is a genetic disorder that primarily affects collagen formation and bone fragility, with no significant connection to the formation of chondrosarcoma. Thus, Ollier disease stands out as the condition that significantly associates with chondrosarcoma due to its inherent risk of tumor development from cartilage lesions.
