Abstract

Fibroosseous 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 fibroosseous pseudotumor of the distal phalanx of great toe in 20-year-old female patient who present with painful mass.

Keywords: great toe, fibroosseous pseudotumor
