Summary

Cutaneous necrosis is a rare complication of interferon treatment. This report details the first case of skin necrosis in a patient treated with interferon alpha-2b for chronic hepatitis C, suggesting treatment cessation may be needed.

Area of Science:

  • Hepatology
  • Dermatology
  • Pharmacology

Background:

  • Interferon therapy is used for chronic hepatitis C.
  • Cutaneous necrosis is a known, albeit rare, adverse effect of interferon treatment.
  • Interferon alpha-2b is a common antiviral medication.

Observation:

  • A patient receiving interferon alpha-2b for chronic hepatitis C developed cutaneous necrosis.
  • Two necrotic lesions appeared during high-dose interferon therapy.
  • The exact mechanism of interferon-induced cutaneous necrosis is not fully understood.

Findings:

  • This is the first reported case of cutaneous necrosis associated with interferon alpha-2b in chronic hepatitis C patients.
  • High doses of interferon may increase the risk of developing cutaneous necrosis.

  • Discontinuation of interferon treatment may be required for lesion healing.

    • Implications:

    • Clinicians should be aware of cutaneous necrosis as a potential complication of interferon therapy.
    • Early recognition and management, potentially including treatment cessation, are crucial for patient outcomes.
    • Further research into the mechanisms of interferon-induced skin necrosis is warranted, with intraarterial injection noted as a potential contributing factor.
