[Cholesterol microemboli].

Cholesterol microemboli are caused by cholesterol crystals released from arteriosclerotic plaques in the major arteries. The clinical picture is illustrated by two case histories with symptoms in the form of myalgia, livedo reticularis and gangrene. The diagnoses were verified by demonstration of cholesterol crystals in the affected tissue. The pathogenesis is illustrated and, on the basis of the literature, it is emphasized that cholesterol microemboli are probably often overlooked clinically and that an increasing incidence must be anticipated on account of the increasing frequency of invasive procedures and treatments of arteriosclerotic vascular disease.
