Xanthomas, also known as xanthoma, xanthomata, or xanthomatosis, is based on the Greek word “xanthos” which means “yellow”. It is a condition characterized by yellowish or orange lipid deposits within the skin.
They may appear on the extremities, buttocks, or all over the body. These fatty growths vary in size, they may be as small as pinheads or as big as grapes. Normally, xanthomas are not painful but they may be itchy and tender. This is often caused by high levels of lipids or fats. Xanthoma may be a symptom of certain diseases such as high blood cholesterol, diabetes, hypothyroidism, cancer, and medication side effects.
