Relevant species
- Most common Tedania ignis (Hawaiian or West Indian fire sponge)
- Found in Florida and Hawaii
- Fibula nolitangere (poison bun sponge)
- Microciona prolifera (red moss sponge)
Clinical Features
- Symptoms caused by contact with sponge
- Pruritic dermatitis and rarely erythema multiforme or anaphylactoid reaction
- Reaction appears between 10 minutes and a few hours of contact
- Starts with pruritus and burning
- Mild reactions resolve in 3-7 days
Differential Diagnosis

Evaluation
Management
- Gently dry skin
- Attempt to remove small spicules embedded in skin
- May use adhesive tape
- Use 5% acetic acid (vinegar) soaks to affected area 10-30 minutes 3-4 times daily
- If unavailable may use 40-70% isopropyl alcohol
- Topical steroids may relieve secondary inflammation
- Tetanus prophylaxis
- Close follow up for wound checks to monitor for infection
