This report details the first Venezuelan case of perforating granuloma annulare in a child. The condition presented as asymptomatic skin lesions on the hands, successfully treated with steroid injections.

Area of Science:

  • Dermatology
  • Pathology

Background:

  • Granuloma annulare is a benign inflammatory skin condition.
  • Perforating granuloma annulare is a rare variant characterized by transepithelial elimination.

Observation:

  • A case of perforating granuloma annulare in an 11-year-old Venezuelan patient is described.
  • The patient presented with asymptomatic, minute, lichenoid papules on the dorsal hands and fingers persisting for two years.
  • Lesions exhibited characteristics of classical granuloma annulare with necrobiosis and transepithelial perforation.

Findings:

  • Histopathological examination confirmed granuloma annulare with necrobiotic changes.
  • Evidence of transepithelial perforation, facilitating collagen and cell debris elimination, was observed.
  • The patient showed a positive response to intralesional steroid injections.

Implications:

  • This case expands the geographic and clinical understanding of perforating granuloma annulare.
  • Highlights intralesional steroids as an effective treatment option for this rare condition.
  • Emphasizes the importance of histopathological correlation for diagnosing rare dermatological variants.
