case_images: Clinical examination revealed a 1.5 x 1.0-cm reddish nodule on the medial side of the toe (Fig 1).
case_images: Magnetic resonance imaging revealed a mass occupying the medial aspect of the distal phalanx, with low signal intensity on T1-weighted images and intermediate to high signal intensity on T2-weighted images.

case_images: Radiological evaluation revealed a soft-tissue mass without calcification, and magnetic resonance imaging (MRI) revealed a mass adjacent to the distal phalanx (Fig 2).
case_images: Histopathological findings. (a) Low-magnification view showing the architecture with ulcerated epidermis. (b) High-magnification view showing myofibroblastic and fibrovascular proliferations, with mature woven bone rimmed by osteoblasts. No evidence of abnormal mitotic activity or cellular atypia was observed.

case_images: Mature bony trabeculae rimmed by osteoblasts were observed in the peripheral area, which was diagnosed as a fibro-osseous pseudotumor (FOP) (Figs 3a and 3b).
case_images: Follow-up image showing no recurrence of the mass after 6 months.
