Foot and ankle problems usually fall into the following categories:
- Acquired from improper footwear, physical stress, or small mechanical changes within the foot.
- Arthritic foot problems, which typically involve one or more joint.
- Congenital foot problems, which occur at birth, are generally inherited.
- Infectious foot problems, which are caused by bacterial, viral, or fungal disorders.
- Neoplastic disorders, usually called tumors, which are the result of abnormal growth of tissue and may be benign or malignant.
- Traumatic foot problems, which are associated with foot and ankle injuries.
Bone tumors are caused by an abnormal growth of cells. They may be benign (noncancerous) or malignant (cancerous). Although rare, bone tumors can occur in the foot and ankle. They can be primary (originating in the bone), or secondary (originating in another part of the body).
Symptoms of a bone tumor may include:
• Fracture from slight injury,
• Bone pain, often at night,
• Occasionally a mass or swelling in the area.
A bone tumor is first diagnosed with x-rays. Advanced imaging modalities may be used to further evaluate the tumor. Surgical removal by a foot and ankle surgeon may be required for a definitive diagnosis.
