What is a characteristic of a pedunculated osteochondroma?

• A. It has a broad base attaching to bone
• B. It is a solitary tumor that metastasizes
• C. It has a stalk or stem sticking out from the normal bone
• D. It is found only in adults

Answer: (C)

A pedunculated osteochondroma is characterized by having a stalk or stem that connects it to the underlying normal bone. This distinctive morphology allows the tumor to appear as though it is hanging off the bone, which is a key feature that differentiates it from other types of bone lesions. In contrast to other bone growths that may have a broader base of attachment, a pedunculated osteochondroma's narrow, stalk-like connection is what defines its appearance and often influences its treatment and diagnostic considerations. Understanding this characteristic is crucial for recognizing osteochondromas on imaging studies and during physical examination. The other options do not accurately describe the nature of a pedunculated osteochondroma. For instance, this tumor is typically benign and does not metastasize, and while solitary tumors can occur, they are not exclusively solitary, as multiple osteochondromas can exist in some cases. Additionally, these tumors can develop in children and adolescents, not just in adults, making the characteristics of a pedunculated osteochondroma distinct and important for accurate identification and management.
