Summary

Cutaneous larva migrans (CLM) is a common tropical skin disease caused by hookworm larvae from pet feces. It presents as itchy, linear skin lesions and typically resolves within months with treatment.

Area of Science:

  • Dermatology
  • Tropical Medicine
  • Parasitology

Background:

  • Cutaneous larva migrans (CLM) is the most frequent tropically acquired dermatosis.
  • It is caused by hookworm larvae, primarily from infected dogs and cats.
  • Risk factors include walking barefoot or sitting on contaminated beaches in endemic areas like the Caribbean and New World.

Purpose of the Study:

  • To describe the etiology, clinical presentation, and treatment of Cutaneous larva migrans.
  • To highlight the epidemiology and risk factors associated with CLM.
  • To inform on the natural course and resolution of the condition in humans.

Main Methods:

  • Review of literature on Cutaneous larva migrans.
  • Identification of causative agents: Ancylostoma braziliense and Ancylostoma caninum.
  • Description of clinical manifestations and therapeutic interventions.

Main Results:

  • CLM lesions, known as creeping eruptions, are characterized by erythematous, raised, vesicular, linear, or serpentine, and intensely pruritic rashes.
  • The condition is caused by hookworm larvae found in pet feces.
  • Humans are accidental dead-end hosts, with the parasite perishing and lesions resolving spontaneously.

Conclusions:

  • Cutaneous larva migrans is a common, treatable dermatosis acquired in tropical regions.
  • Prompt diagnosis and treatment with thiabendazole are effective.
  • Understanding transmission routes is crucial for prevention in at-risk populations.
