An overview of creeping eruption, also known as cutaneous larva migrans, and its causes, symptoms, diagnosis, treatment, and prevention.
Causes:
Infection with parasitic larvae, usually hookworm larvae found in animal feces, results in a creeping eruption. After a direct contact with soil or sand, these larvae penetrate the skin and migrate within, causing characteristic symptoms.
Symptoms:
Symptoms of creeping eruption may include:
-
An itchy, raised, and red rash that resembles tracks or tunnels due to its serpiginous (wavy or linear) appearance.
-
There is intense itching and discomfort along the larval migration path.
-
Localized inflammation, redness, and swelling at the entry point of larvae.
-
Scratching may cause skin abrasions, blisters, or secondary bacterial infections.
Diagnosis:
It is usually diagnosed based on clinical presentation and history of exposure to contaminated soil or sand. Diagnostic methods include:
-
Examination of the skin rash and linear tracks or tunnels suggestive of larval migration.
-
Inquiry about recent travel to tropical or subtropical regions, exposure to sandy or soil environments, or contact with animals.
-
Scraping the affected skin area and examining it under a microscope may reveal hookworm larvae or their characteristic tracks.
Treatment:
There are a number of treatment options available for creeping eruptions that aim to relieve symptoms and eliminate the underlying parasitic infection. These include:
-
Application of topical antiparasitic medications such as thiabendazole or albendazole to the affected area can help kill the larvae and alleviate itching.
-
When multiple lesions or sensitive areas are involved, oral antiparasitic medications may be prescribed.
-
To alleviate itching and inflammation associated with creeping eruptions, anti-itch creams, corticosteroids, or oral antihistamines may be recommended.
-
In order to prevent secondary bacterial infections, keep the affected skin clean and dry, avoid scratching, and apply antiseptic ointments.
Prevention:
A few strategies for preventing creeping eruptions include avoiding contaminated soil or sand and taking preventive measures when visiting endemic regions.
-
When exposed to sandy or soil environments where hookworm larvae may be present, wearing shoes or protective footwear can help prevent skin contact and infection.
-
In areas frequented by dogs or cats, avoiding direct skin contact with contaminated soil or sand can reduce the risk of larval penetration.
-
Infections caused by parasites can be prevented by practicing good hygiene, including thorough handwashing after outdoor activities.
In conclusion, creeping eruption is a parasitic skin infection caused by hookworm larvae penetrating the skin and migrating within the epidermis. Early diagnosis and appropriate treatment are crucial for relieving symptoms and preventing complications. Practicing good hygiene and avoiding contact with contaminated soil and sand can help reduce the risk of creeping eruptions.
