Cholesterol embolism in a patient with inflammatory abdominal aortic aneurysm.

A 66-year-old man whose renal function had progressively deteriorated had an elevated blood pressure and also was found to have an inflammatory abdominal aortic aneurysm (AAA). Blood examination revealed that he had eosinophilia. Livedo reticularis of the toes developed, and a skin biopsy specimen showed embolization of atheromatous plaques in the arterioles of the subcutaneous tissue. Progressive enlargement of inflammatory AAA may have dislodged the atheromatous plaques, resulting in cholesterol embolism.
