Cutaneous larva migrans

**Definition:** A disease caused by an infection with the parasitic worm larvae, commonly Ancylostoma braziliense, A. caninum, or Uncinaria stenocephala. This disease is characterised by intense pruritus and erythematous, serpiginous lesions due to migration of parasitic larvae in the upper dermis where the larvae penetrate the skin. Transmission is by direct contact with larvae from soil or sand contaminated with dog or cat faeces (by percutaneous migration of larvae).
