Tumor as an indication for amputation in the foot.

When a benign or malignant tumor presents itself in the foot, amputation may, at times, be necessary for complete eradication. Suspected malignancies require detailed general evaluation and oncology consultation. Biopsy is the gold standard for diagnosis. Depending on the type of tumor identified, resection margins of varying degrees may be necessary. Cases are used to illustrate the principles of tumor care.
