Xanthomas of the Achilles Tendon

A Xanthoma (pronounced zan-thoh-muh), sometimes referred to as a skin growth, is a skin condition where lipids (fats) build up under the skin and form a deposit of fat. The deposits can vary in size; some are very small while others can be as big as 3 inches in diameter. Xanthomas are more common among older adults and patients with high levels of blood lipids.

 Xanthomas can show up anywhere on the body but most commonly appear on elbows, joints, tendons, knees, hands, buttocks, and feet. They can sometimes indicate diseases or medical conditions that involve an increase in blood lipids.

• Diabetes
• Cancer
• Hyperlipidemia
• Inherited metabolic disorders such as familial hypercholesterolemia

A Xanthoma on the Achilles tendon would show up as a sore or bump under the skin running along the tendon. The sore/bump will be yellow and have distinct edges. Dr. Danciger can check the sore or bump and diagnose whether or not it is in fact a Xanthoma. This diagnosis often requires only a visual inspection, but may require a blood test as well to test blood lipid levels and check for diabetes and liver function.

The Xanthoma itself should not cause the patient any pain, but it may be an indicator of a bigger problem. If you notice signs of a Xanthoma anywhere on your body don't hesitate to schedule an appointment with Dr. Danciger to get a diagnosis.
