title: Cholestrol and cholesteryl ester content in normal and pathologic scale.
abstract: Using a sensitive new assay, we have measured the cholesteryl ester and cholesterol contents of stratum corneum from callus, normal skin, psoriatic lesions (plantar and nonplantar), and lamellar ichthyotic lesions (plantar and nonplantar). Cholesteryl ester content of normal stratum corneum was significantly higher than that of callus, suggesting that callus was not a suitable control tissue for further biochemical studies involving sterol content of stratum corneum. Both psoriatic and lamellar ichthyotic scale have increased levels of free cholesterol and decreased levels of esterified cholesterol when compared to appropriate controls.
