🐾 338.1 · Cutaneous Larva Migrans (Creeping Eruption)

Nelson Textbook of Pediatrics 22nd Edition | Cutaneous larva migrans (CLM) is caused by skin-penetrating larvae of animal hookworms, most commonly Ancylostoma braziliense (dogs/cats). Humans are accidental hosts; larvae cannot complete their life cycle and migrate in the epidermis, causing intensely pruritic, serpiginous, erythematous tracks that advance 1-2 cm/day. Commonly on feet, buttocks, thighs. Diagnosis is clinical. Treatment: ivermectin (single dose) or albendazole (3 days). Topical thiabendazole for limited lesions. Prevention: avoid walking barefoot on contaminated soil, deworm pets.
