Figure

  • Fig. 1 A solitary, tender, and reddish nodule on the right third toe.

  • Fig. 2 (A) The lesion had variable cellularity and consisted of a mixture of loosely or compactly arranged fibroblasts and trabeculae of the bone showing varying degrees of maturation (H&E, ×40). (B) Newly formed trabeculae of the osteoid and bone were distributed haphazardly without zoning phenomenon. The trabeculae of the bone were rimmed by fibroblasts and osteoblasts (H&E, ×200).
