ComplicationsBy Mayo Clinic staff
Lymphedema in your arm or leg can lead to serious complications, such as:
- Infections. Lymphedema makes your affected arm or leg particularly vulnerable to infections. Possible infections include cellulitis — a serious bacterial infection of the skin — and lymphangitis — an infection of the lymph vessels. Any injury to your arm or leg can be an entry point for an infection.
- Lymphangiosarcoma. This rare form of soft tissue cancer can result from the most-severe cases of untreated lymphedema. Possible signs of lymphangiosarcoma include blue-red or purple marks on the skin.
