Elemental mercury poisoning mimicked Kawasaki disease in a child with severe hypertension. Environmental toxins were suspected when his brother presented with similar symptoms, leading to a diagnosis of mercury intoxication.

Area of Science:

  • Pediatric toxicology
  • Environmental health
  • Clinical diagnostics

Background:

  • Kawasaki disease is a critical diagnosis in children presenting with systemic symptoms, fever, and rash.
  • Severe hypertension in children can indicate serious underlying pathology, including endocrine or oncologic causes.
  • Environmental toxin exposure is a less common but crucial differential diagnosis in pediatric systemic illness.

Observation:

  • A 3-year-old boy presented with symptoms mimicking Kawasaki disease, including oropharyngeal and extremity changes, alongside severe hypertension.
  • Initial investigations for a catecholamine-secreting tumor were negative.
  • The patient's 20-month-old brother developed similar symptoms, prompting consideration of toxic exposure.

Findings:

  • The two brothers were diagnosed with elemental mercury poisoning.

  • Elemental mercury poisoning can present with a syndrome resembling acrodynia.
  • Literature review on mercury intoxication, its historical context, clinical features, treatment, and radiologic findings is presented.

    • Implications:

    • This case highlights the importance of considering environmental toxins, specifically elemental mercury, in the differential diagnosis of pediatric systemic illnesses that mimic other conditions.
    • Early recognition and diagnosis of mercury poisoning are crucial for appropriate management and preventing long-term sequelae.
    • Awareness of mercury's diverse clinical presentations can aid clinicians in diagnosing this unusual but treatable condition.
