Long-term hydroxyurea (HU) treatment can cause severe skin reactions, including keratoses and potential skin cancer. Withdrawal of HU led to improvement in a patient with rapidly developing skin lesions.

Area of Science:

  • Dermatology
  • Oncology
  • Pharmacology

Background:

  • Hydroxyurea (HU) is a medication used for chronic myeloid leukemia.
  • Long-term HU use is associated with specific skin manifestations like atrophy and erythema.
  • The potential for severe skin toxicity with HU requires careful monitoring.

Observation:

  • A 60-year-old patient on long-term HU therapy developed unusual, rapidly progressing skin keratoses.
  • These lesions mimicked carcinomatous transformation.
  • The patient's lesions worsened with continued HU treatment.

Findings:

  • The clinical presentation and timeline strongly suggested hydroxyurea-induced keratoses.
  • Withdrawal of hydroxyurea led to the resolution of the patient's severe skin lesions.

  • Literature review identified a similar case involving actinic keratoses and skin carcinomas.

    • Implications:

    • Hydroxyurea may play a role in the development of epithelial skin cancers.
    • Understanding the interaction between hydroxyurea and keratinocytes is crucial for managing its dermatological side effects.
    • This case highlights the potential for severe, cancer-like skin reactions to hydroxyurea.
