Cholesterol emboli, a rare complication of anticoagulation therapy, can manifest as painful skin lesions. This case highlights the importance of considering arterial emboli in patients on anticoagulant medications.

Area of Science:

  • Vascular Medicine
  • Dermatology
  • Pharmacology

Background:

  • Anticoagulation therapy is crucial for managing thromboembolic disorders.
  • Complications of anticoagulation can include paradoxical embolism.
  • Cholesterol crystal embolism is a recognized, albeit rare, adverse effect of certain anticoagulant therapies.

Observation:

  • A 71-year-old patient presented with sudden onset of painful, livid erythema on the right foot.
  • Clinical examination and subsequent histological analysis revealed the presence of cholesterol emboli.

Findings:

  • The cholesterol emboli were determined to be induced by phenprocoumon therapy initiated five months prior.
  • This diagnosis was established based on the characteristic clinical presentation and pathological findings.

Implications:

  • Arterial emboli are a rare but significant complication that can occur during anticoagulation therapy.
  • Clinicians should include cholesterol emboli in the differential diagnosis for patients experiencing unexplained skin lesions while on anticoagulants.
  • Early recognition and management are crucial to prevent further embolic events and potential organ damage.
