Abstract:
Malignant peripheral nerve sheath tumors (MPNSTs) usually arise in soft tissues; they are rarely found in the bone. This paper reports a case of MPNST in the foot and ankle joint involving the distal tibia, talus, calcaneus, navicular, medial intermediate, and lateral cuneiform, cuboid, and 2nd to 4th metatarsal bone. Palliative treatment was performed. The authors encountered a patient with intraosseous MPNST of the midfoot who presented with nonspecific clinical and radiologic findings. This case shows that a high index of suspicion and a histopathology examination, including immunohistochemistry, will be necessary for an accurate diagnosis.
