Cutaneous mercury granuloma: a case report.

Area of Science:

• Dermatology
• Toxicology
• Environmental Medicine

Background:

• Cutaneous mercury (Hg) granuloma is a rare condition resulting from direct elemental mercury introduction into tissues.
• Typically, localized mercury deposits cause minimal systemic effects.

Observation:

• This report details a case of cutaneous mercury granuloma with severe chronic local wounds.
• The patient exhibited significant systemic toxicity, including abdominal pain, visual disturbances, and psychiatric abnormalities.

Findings:

• Elemental mercury introduced into the skin can lead to both localized tissue damage and systemic mercury poisoning.
• The severity of systemic effects can be disproportionate to the initial trauma.

Implications:

• Highlights the importance of recognizing cutaneous mercury granuloma as a potential source of systemic mercury toxicity.
• Underscores the need for thorough evaluation of systemic symptoms in patients with suspected elemental mercury exposure.
• Emphasizes prompt and appropriate management to mitigate both local and systemic health consequences.
