A 53-yo man noted an itchy, red rash on his ankle after a trip to Brazil. He was bitten while on a beach and covered the bite with a bandage. The bite mark extended itself 1 cm to 2 cm per day in a serpiginous pattern. He was otherwise well. What is it?
Lymphatic filariasis (Brugia malayi)
Cutaneous larva migrans
Chagas disease (T. cruzi)
Lyme erythema migrans
Tungiasis (burrowing flea)
You are correct. Cutaneous larva migrans is a common tropical/subtropical dermatosis caused by penetration and migration of hookworm larvae. The highly pruritic, advancing, serpiginous eruption is typically self-limiting.
