Abstract

Fibro-osseous pseudotumor is an extremely rare benign lesion which is fast-growing and painful. It is often misdiagnosed as a malignancy, but it is a noninvasive entity and can be cured by simple resection. We report a case of fibro-osseous pseudotumor of the distal phalanx of great toe in 20-year-old female patient who present with painful mass.

Figure

• 

  Figure 1. Initial anteroposterior and lateral views of left great toe show a brown-colored solid mass with granulation tissue.

• 

  Figure 2. The anteroposterior and lateral radiographs of the left foot show that bony projection arose from the subungual portion of the distal phalanx of the great toe without periosteal reaction.

• 

  Figure 3. The lesion contained fibroblast proliferation and woven bone formation (H&E ×40).

• 

  Figure 4. The Fibroblasts are arranged in short fascicles (hollow arrow) with some osteoclast-like giant cells (black arrow) (H&E ×200).

• 

  Figure 5. The anteroposterior and lateral radiographs of the left foot show no abnormality.
