In this paper the basic pathogenesis of cholesterol crystal embolization (CCE) is described, its clinical characteristics are presented and diagnosis and therapy are discussed. The main focus will be on the cutaneous manifestations; however, considering that CCE is a systemic illness, findings in other organs will also be highlighted, particularly the commonly involved renal and gastrointestinal systems.
