4. Fig 3
Sections of the lesion showed an interlacing network of thin bone trabeculae uniformly distributed in loose stromal vascular connective tissue. Osteoblasts rim the osteoid trabeculae prominently and are accompanied by numerous osteoclast-like, multinucleated giant cells (hematoxylin and eosin staining; original magnification ×10).
