Cholesterol crystal embolism (CCE) is a rare condition often seen in older men with atherosclerosis. Early diagnosis through skin biopsy is crucial for managing this condition.

Area of Science:

  • Vascular Medicine
  • Dermatology
  • Pathology

Background:

  • Cholesterol crystal embolism (CCE) is an infrequent vascular complication.
  • It predominantly affects males over 60 with generalized arteriosclerosis.
  • Risk factors include angiographic procedures, vascular surgery, and anticoagulant therapy.

Observation:

  • A case of CCE is presented in a patient with multiple risk factors.
  • The patient exhibited the characteristic triad of leg/foot pain, livedo reticularis, and palpable pedal pulses.
  • Diagnosis was confirmed by identifying cholesterol crystals in skin biopsy arterioles.

Findings:

  • Skin manifestations are common in CCE.
  • Microscopic identification of cholesterol crystals in arterioles is diagnostic.

  • The pathognomonic triad aids in clinical suspicion.

    • Implications:

    • Increased awareness of CCE is vital for clinicians.
    • Early diagnosis and treatment are essential for managing CCE.
    • Skin biopsy is a key diagnostic tool for CCE.
