Cholesterol emboli pathology
Authors: Dr Achala Liyanage, Dermatology Fellow, Waikato Hospital, Hamilton, New Zealand; Assoc Prof Patrick Emanuel, Dermatopathologist, Auckland, New Zealand. January 2015.
Cholesterol embolism occurs spontaneously or following vascular surgery. Cutaneous manifestations range from purpura and livedo to ulceration and gangrene.
Microscopically, clefts indicating the sites of cholesterol deposition are seen in arterioles and arteries in the dermis and subcutis. Fibrin thrombi often surround the cholesterol. There may be extensive surrounding necrosis.
