Tumors of Foot and Ankle
- Bone Lesions:
- enchondroma: (relatively common)
- osteoid osteoma: (talus, navicular, or calcaneus)
- fibrous dysplasia
- adamantinoma (foot)
- metastatic lung cancer (? GI or GU)
- subungual exostosis, may develop on a distal phalanx, esp. big toe
- often there is a history of trauma
- excision is indicated when elevation of the nail produces pain
- the history and location of the serve to distinguish it from a osteochondroma;
- giant cell tumor of bone
- Soft Tissue Lesions:
- ganglionic cyst: most common lesion in the foot, since this arises from the tarsal joints, it may be necessary to lift up the EDB to see the lesion;
- melanoma is the most common primary malignant tumor of the foot, occurring most commonly on the plantar skin;
- synovial sarcoma
- clear cell sarcoma: upto one half of these tumors occur in the foot;
- giant cell tumor of tendon sheath
- locally aggressive idiopathic proliferative fascitis of the plantar aponeurosis that is usually bilateral;
- like Dupuytrens's contractures in the hand, this disease (aka Lederhosen syndrome) presents as discrete plantar nodules often seen in non
wt bearing areas (esp medial plantar);
- surgical excision is rarely successful but may be required for large, painful nodules;
- excision must include the entire slip of plantar fascia from origin to insertion in order to avoid recurrence rates of up to 60%
