Chloracne from pentachlorophenol-preserved wood

Area of Science:

• Dermatology
• Environmental Toxicology
• Occupational Health

Background:

• Pentachlorophenol (PCP) is a chemical used in lumber treatment.
• Technical grade PCP can be contaminated with polychlorinated aromatic compounds, including dioxins and furans.
• These contaminants are known human health hazards.

Observation:

• A patient presented with chloracne, a severe acne-like condition.
• The patient's exposure to PCP-treated lumber was identified as the likely cause.
• Chloracne developed subsequent to occupational exposure.

Findings:

• Percutaneous absorption of dioxins and furans from contaminated lumber is the presumed mechanism of disease.
• The patient's chloracne was successfully treated with oral isotretinoin.
• Isotretinoin demonstrated efficacy in managing PCP-induced chloracne.

Implications:

• Highlights the risk of chloracne from occupational exposure to contaminated wood preservatives.
• Suggests a potential treatment avenue for environmentally induced chloracne.
• Underscores the importance of managing contaminants in industrial chemicals.
