What is the most common bone tumor in the digits?

• A. Osteoid osteoma
• B. Enchondroma
• C. Osteochondroma
• D. Giant cell tumor

Answer: (B)

Enchondroma is the most common bone tumor in the digits. It’s a benign cartilaginous tumor that arises within the medullary cavity of the small hand and foot bones, especially the phalanges. Because of its central location inside these tiny bones, enchondromas are frequently seen in the digits and often discovered incidentally or after causing mild swelling or painless abnormalities. Radiographs typically show a central lucent lesion within the bone, sometimes with chondroid calcifications and possible endosteal scalloping. The other tumors are less typical for the digits. Osteoid osteoma tends to occur in long bones of younger patients and presents with a painful, nocturnal ache that responds to NSAIDs, rooted in a cortical nidus rather than a central medullary lesion. Osteochondroma arises from the metaphysis of long bones and is an exostosis rather than a medullary cartilaginous tumor, making it uncommon in the small hand/foot bones. Giant cell tumor usually involves the epiphysis of long bones in adults and is rare in the tiny bones of the digits.
