Summary

Dermabrasion effectively treated hyperkeratotic plaques in a patient with congenital poikiloderma (Dowling-Degos disease), offering an alternative to long-term retinoid therapy for precancerous lesions.

Area of Science:

  • Dermatology
  • Oncology
  • Medical Genetics

Background:

  • Congenital poikiloderma, specifically Dowling-Degos disease, presents a heterogeneous clinical picture.
  • Patients with this condition have an elevated risk of developing skin malignancies, including squamous cell carcinoma.
  • Hypertriglyceridemia (Frederickson type IV) can complicate treatment choices.

Observation:

  • A male patient with congenital poikiloderma developed Bowen's disease and early squamous cell carcinoma.
  • The patient had co-existing hypertriglyceridemia, precluding long-term retinoid therapy for tumor prophylaxis.
  • Hyperkeratotic plaques were treated using dermabrasion.

Findings:

  • After six months of dermabrasion, complete healing was observed in several hyperkeratotic plaques.

  • Minor keratoses persisted in a limited number of treated areas.
  • Long-term follow-up data is pending.

    • Implications:

    • Dermabrasion represents a viable therapeutic option for managing hyperkeratotic lesions in congenital poikiloderma, especially when retinoids are contraindicated.
    • This case highlights the importance of vigilant monitoring for malignancies in patients with congenital poikiloderma.
    • Further research is needed to establish the long-term efficacy and safety of dermabrasion in this patient population.
