Cholesterol microemboli, caused by plaque rupture, present with pain, skin lesions, and gangrene. Diagnosis requires identifying cholesterol crystals in tissues, and incidence is rising due to medical procedures.

Area of Science:

  • Cardiovascular Medicine
  • Pathology

Background:

  • Cholesterol microemboli arise from the rupture of atherosclerotic plaques in major arteries.
  • These emboli consist of cholesterol crystals that obstruct small blood vessels.

Observation:

  • The study presents two cases of cholesterol microemboli syndrome.
  • Clinical manifestations included myalgia, livedo reticularis, and gangrene.
  • Diagnosis was confirmed by histological identification of cholesterol crystals in affected tissues.

Findings:

  • Cholesterol microemboli are likely underdiagnosed in clinical practice.
  • The pathogenesis involves the release of cholesterol crystals from arterial plaques.

Implications:

  • An increasing incidence of cholesterol microemboli is anticipated.

  • This rise is linked to the growing number of invasive vascular procedures and treatments for arteriosclerotic disease.
  • Increased clinical awareness and diagnostic vigilance are necessary.
