Xanthomas
Xanthomas
Xanthomas (pronunciation: zan-tho-mas) are lipid deposits that form in the skin and tendons. They are often associated with certain medical conditions, such as hyperlipidemia, diabetes, and biliary cirrhosis.
Etymology
The term "Xanthomas" is derived from the Greek words "xanthos" meaning yellow and "oma" meaning tumor. This is due to the yellowish appearance of the deposits.
Types of Xanthomas
There are several types of xanthomas, each associated with specific areas of the body and certain medical conditions. These include:
- Eruptive xanthomas: These appear as small, yellowish bumps on the skin, often on the buttocks or thighs. They are typically associated with high levels of triglycerides in the blood.
- Tendinous xanthomas: These form in the tendons, particularly in the hands and feet. They are often associated with familial hypercholesterolemia, a genetic condition that results in high levels of cholesterol in the blood.
- Tuberoeruptive xanthomas: These are larger and more nodular than eruptive xanthomas, and are often found on the elbows and knees. They are typically associated with hyperlipoproteinemia type III.
- Xanthelasma: These are flat, yellowish patches that form on or around the eyelids. They are often associated with hypercholesterolemia and hyperlipoproteinemia type IIa.
Treatment
Treatment for xanthomas typically involves addressing the underlying medical condition that is causing the lipid deposits. This may involve dietary changes, medication, or in some cases, surgical removal of the deposits.
