Background

Life and Habitat

  • Approximately 5000 species of sponge
  • Generally stationary and attach to see floor or coral beds

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 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
