Background
- Cnidaria larvae get trapped, release toxin
- Nematocysts of the larval forms of sea anemones: Edwardsiella lineata
- Thimble jellyfish: Linuche unguiculata
- Not be confused with cercarial dermatitis, which is caused by freshwater schistosomes or coastal water clam diggers
Clinical Features
- Rash generally under the garments worn by bathers and swimmers (where the organisms are trapped after the person leaves the water)
- Versus Cercarial dermatitis, which is occurs on the exposed skin outside of close-fitting garments

Evaluation
- Typically a clinical diagnosis
Management
- Thoroughly wash and dry bathing clothes.
- Consider oral diphenhydramine for pruritis.
Disposition
- Discharge home
- Return precautions for signs of bacterial superinfection of the lesions.
