Podcast #378: Is That a Brown Recluse Spider Bite?

Author:  Michael Hunt, MD

Educational Pearls:

 

• Use the mnemonic NOT RECLUSE to rule out a brown recluse spider bite:

• Numerous bites (recluse spiders will bite once)

• Occurence (recluse bites between April- October)

• Timing (recluse spiders are… get this…  reclusive)

• Red (recluse bites are white/pale)

• Elevated (recluse bites are flat)

• Chronic (recluse bites are acute)

• Large (recluse wounds are small)

• Ulceration, early (recluse bites ulcerate between 7-14 days)

• Swollen (recluse bites are flat)

• Exudative (recluse bites are dry)
