- Itchy tropical dermatosis caused by dog or cat hookworm in tropical countries
Background
Microbiology
- Caused by non-human hookworms, including Ancylostoma braziliense (most common), Ancylostoma caninum, or Uncinaria stenocephala dog and cat hookworms
- Humans are a dead-end incidental host
- Rarely, caused by other zoonotic hookworms
Clinical Manifestations
- Characterized by appearance of serpiginous, raised, erythematous, burrowing tracks typically found on the feet
- Lesions are usually itchy, may be painful
- Progress more slowly than larva currens
Management
- Lesions with spontaneously resolve given time, but if the pruritis is severe then may benefit from treatment
- Ivermectin 200 mcg/kg po once, can be repeated a second time
- Alternatively, albendazole 200 to 400 mg po bid for 3 to 5 days (with food)
