Summary
A chemical pesticide containing thiamethoxam caused irritant contact dermatitis, leading to nail matrix damage and onychomadesis (nail separation). This case highlights a novel adverse effect of this common insecticide on fingernails and toenails.
Area of Science:
- Dermatology
- Toxicology
- Nail Medicine
Background:
- Irritant contact dermatitis can affect the nail unit, potentially causing subclinical nail matrix damage and onychomadesis.
- Onychomadesis, or nail separation, may initially be subtle and become apparent later.
