This study details muscle biopsy findings in acute arsenic intoxication causing severe rhabdomyolysis. Key observations include hypercontracted fibers, myofibrillar damage, and lipid vacuoles in muscle cells.

Area of Science:

  • Toxicology
  • Pathology
  • Muscle Biology

Background:

  • Arsenic intoxication can lead to severe health consequences, including rhabdomyolysis.
  • Understanding the histological changes in muscle is crucial for diagnosing and managing arsenic toxicity.

Observation:

  • A case of acute voluntary massive arsenic intoxication was investigated.
  • Muscle biopsy was performed to examine the histological effects.

Findings:

  • The muscle biopsy revealed perifascicular hypercontracted fibers.
  • Myofibrillar disruption, mitochondrial abnormalities, and abundant cytoplasmic lipid vacuoles were observed.

Implications:

  • These findings contribute to the understanding of arsenic-induced muscle pathology.
