Figure

  • Figure 1 (A) Posteroanterior and (B) oblique radiographs of the hand show large soft tissue mass with ossification on the fifth metacarpal head to shaft area, reveal a mature turret exostosis.

  • Figure 2 (A) Initial bone scanreveals an active heterotopic ossification lesion around the fifth metacarpal area and (B) six months follow up bone scan shows decreased hot uptake lesion of the fifth metacarpal area.

  • Figure 3 (A) Excised mass and (B) horizontally cut.

  • Figure 4 Histopathologic examinationdefinitely diagnosed as turret exostosis including mature bone, cartilage and fiber membrane. (A) H&E stain ×100. (B) ×200.

  • Figure 5 Gross pictures after one year and six months from surgery demonstrate the fifth interphalangeal joint and the fifth MCP joint are capable of full flexion.

  • Figure 6 Radiographs of hand after one year and six months from surgery shows no definite evidence of recurrence.
