Xanthomas are small skin blemishes that happen due to a buildup of fats under the surface of the skin. They can also develop on internal organs. The bumps themselves are not dangerous.

Context Explanation

However,... There are many types of xanthomas, which are differentiated by their underlying cause and part of the body they affect. What causes xanthomas? In general, xanthomas are caused by excessive fat, in the form of cholesterol or triglycerides, within the blood.

Insight Material

Tendon xanthomas (tendinous xanthoma) are slowly enlarging subcutaneous nodules usually found attached to the Achilles tendon or tendons over the knuckles. They are smooth, firm to palpation, and mobile. A xanthoma (pl. xanthomas or xanthomata) (condition: xanthomatosis) is a deposition of yellowish cholesterol -rich material that can appear anywhere in the body in various disease states. [2] Xanthomas are localized lipid deposits within an organ system.

Final Conclusion

They are often an important sign of systemic disease. To avoid the high morbidity and mortality associated with the underlying systemic condition, it must be promptly diagnosed and treated. Xanthomas occur on the eye lids, usually on both sides. They are yellow, soft, and slightly raised bumps, and are fairly common. They consist of cholesterol deposits and can be removed for cosmetic problems as they are not a health risk. Xanthomas are yellowish, waxy skin deposits resulting from the local accumulation of fats, primarily cholesterol, within immune cells near the skin’s surface.

These growths indicate an underlying systemic issue, often related to the body’s management of fats in the bloodstream.
