Sarcoidosis versus foreign-body granulomas.

Summary

A delayed skin reaction occurred 10 years after a shell explosion injury. Silicon particles were identified in granulomas, suggesting a foreign-body reaction to the injury.

Area of Science:

  • Dermatology
  • Pathology
  • Toxicology

Background:

  • Delayed-onset skin manifestations can occur years after significant trauma.
  • Foreign-body reactions can mimic granulomatous diseases like sarcoidosis.

Observation:

  • A 42-year-old male presented with a papulonodular exanthema.
  • The eruption appeared 10 years after a shell explosion injury.

Findings:

  • Histopathology was inconclusive for differentiating sarcoid-like granulomas from foreign-body granulomas.
  • X-ray spectroanalytic examination confirmed the presence of silicon particles within epithelioid cell granulomas.

Implications:

  • This case highlights silicon as a potential cause of delayed granulomatous skin reactions.

  • X-ray spectroanalysis is crucial for identifying inorganic foreign materials in challenging dermatopathological diagnoses.
  • Understanding the long-term consequences of blast injuries is important for clinical management.
