Question

Difference between osteoid osteoma and benign osteoblastoma

Answer 1

Explanation:

Histologically, osteoid osteoma and osteoblastoma are similar, containing osteoblasts that produce osteoid and woven bone. Osteoblastoma, however, is larger, tends to be more aggressive, and can undergo malignant transformation, whereas osteoid osteoma is small, benign, and self-limited.
