Xanthoma planum is a medical condition characterized by yellowish patches on the skin caused by an accumulation of lipid in macrophage immune cells. The word xanthoma planum is spelled using the International Phonetic Alphabet (IPA) as /zanˈθoʊmə ˈpleɪnəm/. The first part of the word, xanthoma, is spelled with a silent "x" and a "th" sound represented by the letter "θ". The second part, planum, is pronounced with a long "a" sound and a soft "n" sound represented by the letter "n". Understanding IPA can help with the pronunciation of complex medical terms.
Xanthoma planum is a medical term used to describe a benign skin condition characterized by the development of flat, yellowish, or orange-colored papules or plaques on the surface of the skin. These lesions are typically painless and exhibit a smooth texture.
Xanthoma planum is primarily caused by a buildup of lipids, particularly cholesterol, within certain cells called histiocytes. The histiocytes accumulate in the dermis, thus resulting in the appearance of the characteristic papules or plaques on the skin.
This condition is often associated with underlying disorders related to lipid metabolism, such as familial hypercholesterolemia or dysbetalipoproteinemia. The elevated levels of cholesterol in these conditions lead to the formation of xanthomas.
Xanthoma planum typically affects middle-aged or older individuals, and commonly occurs on the palms, elbows, knees, buttocks, or other areas where the skin folds or experiences friction. It can also manifest in the tendons, particularly the Achilles tendon.
Treatment options for xanthoma planum typically focus on managing the underlying lipid disorder through lifestyle modifications, medications, or surgical interventions, if necessary. In some cases, cryosurgery or laser therapy may be employed to remove the lesions for aesthetic reasons. Regular monitoring and management of lipid levels are crucial to prevent further development or worsening of xanthomas.
While xanthoma planum is a benign condition and does not pose significant health risks in itself, its presence may indicate an underlying lipid disorder that requires attention and treatment to prevent complications such as heart disease.

The word xanthoma planum has its origins in the Greek language.
- Xanthoma is derived from the Greek words xanthos meaning yellow and oma meaning tumor or mass. It refers to a group of disorders characterized by the formation of yellowish deposits of fat or cholesterol beneath the skin.
- Planum is a Latin word meaning flat or level. In this context, it describes the type of xanthoma that appears as flat yellowish lesions on the skin.
Therefore, xanthoma planum is a medical term that translates to flat yellow tumor.
