    • Found in Florida and Hawaii
  • Fibula nolitangere (poison bun sponge)
  • Microciona prolifera (red moss sponge)

Clinical Aspects

  • 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 pruritis and burning
    • May progress to local edema, proximal joint swelling, or vesiculation
    • When large areas of skin are involved, patients can have fever, malaise, dizziness, nausea, muscle cramps
  • Mild reactions resolve in 3-7 days

Treatment

  • Gently dry skin
  • Attempt to remove small spicules imbedded 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
