What skin condition is characterized by fatty pockets?

The skin condition characterized by fatty pockets is known as xanthomas. These lesions appear as yellowish plaques or nodules, which develop due to the accumulation of lipids (fats) within skin cells. Xanthomas often arise in areas such as the elbows, knees, and eyelids and are linked to underlying metabolic disorders, particularly those that result in abnormal lipid levels in the blood. The presence of these fatty deposits can signal a need for medical evaluation regarding cholesterol levels or other health issues related to lipid metabolism.

In contrast, the other listed conditions do not involve fatty deposits. Psoriasis is primarily an autoimmune disorder characterized by an overproduction of skin cells leading to thick, scaly patches. Eczema is an inflammatory condition that results in red, itchy skin often seen in response to allergens or irritants. Acne is related to clogged pores and inflammation due to sebum production and bacteria rather than fatty pockets in the skin. Each of these conditions has distinct characteristics and causes, making xanthomas unique in its association with fatty accumulation in the dermis.
