Summary
This summary is machine-generated.

Granuloma annulare can be triggered by nickel exposure. A positive patch test confirmed nickel sulfate as the cause in this case.

Area of Science:

  • Dermatology
  • Allergology

Background:

  • Granuloma annulare is a benign inflammatory skin condition.
  • Cutaneous reactions to metals are increasingly recognized.

Observation:

  • A patient presented with granuloma annulare.
  • The condition appeared after direct contact with nickel-containing objects.

Findings:

  • Patch testing with 5% nickel sulfate yielded a positive result.
  • This confirms nickel as the causative agent for the granuloma annulare.

Implications:

  • Highlights the importance of metal patch testing in suspected contact-induced granuloma annulare.
  • Suggests nickel allergy as a potential trigger for this specific dermatosis.
