The vast majority of patients with lipid abnormalities are detected by the laboratory, either as part of the workup of a patient with CVD or as part of a preventive screening strategy. Extremely high levels of chylomicrons or VLDL particles (triglyceride level above 1000 mg/dL or 10 mmol/L) result in the formation of eruptive xanthomas (Figure 28–1) (red-yellow papules, especially on the buttocks [eFigure 28–2]). High LDL concentrations result in tendinous xanthomas on certain tendons (Achilles, patella, back of the hand [eFigures 28–3, 28–4, 28–5]). Such xanthomas usually indicate one of the underlying genetic hyperlipidemias. Lipemia retinalis (cream-colored blood vessels in the fundus) is seen with extremely high triglyceride levels (above 2000 mg/dL or 20 mmol/L).
