Cutaneous larva migrans infection in the pediatric foot. A review and two case reports
1Children's Hospital of Philadelphia, PA, USA.
Abstract:
Cutaneous larva migrans is the result of infestation of human skin by helminth larvae, which burrow through the epidermis. This route of infestation makes the foot a typical site for origination of this infection. Children, who frequently play barefoot in locations where the most common of the helminth larvae, the dog and cat hookworms, are endemic, are at particular risk for this disorder. This article reviews the differential diagnosis of cutaneous larva migrans and current concepts in management. Two cases of related children who presented to their pediatricians with this condition are reported.
Insights
Cutaneous larva migrans, a skin infestation by helminth larvae, commonly affects feet, especially in children playing barefoot in endemic areas. This review covers diagnosis and management of this parasitic infection.
Area of Science:
- Medical Parasitology
- Dermatology
- Pediatrics
Background:
- Cutaneous larva migrans (CLM) is a human skin infestation caused by helminth larvae.
- The condition results from larvae burrowing through the epidermis, often originating on the feet.
- Dog and cat hookworms are the most common causative agents.
Observation:
- Children playing barefoot in endemic areas are at high risk.
- Two pediatric cases of CLM are presented.
- The article reviews differential diagnosis and current management strategies.
Findings:
- CLM presents with characteristic migratory serpiginous lesions on the skin.
- Diagnosis relies on clinical presentation and patient history, especially regarding exposure.
- Prompt diagnosis and treatment are crucial to prevent complications.
Implications:
- Understanding CLM epidemiology aids in prevention strategies, particularly for at-risk populations.
- Effective management reduces patient discomfort and prevents secondary infections.
- This review provides valuable insights for clinicians managing CLM cases.
