Cutaneous Larva Migrans: What You Need to Know

When dealing with cutaneous larva migrans, a skin condition caused by the migration of hookworm larvae beneath the epidermis, producing itchy, winding tracks. Also known as creeping eruption, it often shows up after walking barefoot on contaminated beaches. The culprit, hookworm larvae, the infectious stage of animal hookworms that can penetrate human skin, thrives in warm, humid climates. Effective treatment usually involves antiparasitic medication, drugs such as albendazole or ivermectin that kill the migrating larvae, and prevention relies on proper footwear protection, wearing shoes or sandals to stop larvae from entering the skin. In short, cutaneous larva migrans is a tropical skin infection that requires quick diagnosis, targeted drugs, and simple barrier measures.

How It Appears and How to Spot It

The skin lesions look like raised, serpentine lines that slowly crawl a few millimeters each day. These tracks are the path of the larvae as they feed on tissue, causing intense itching and occasional secondary infection. Diagnosis is usually clinical – doctors recognize the pattern and ask about recent travel to sandy, coastal areas. When the picture isn’t clear, a skin biopsy can confirm the presence of larvae. Because the condition mimics other dermatological issues such as allergic rash, sunburn‑related inflammation, or even early skin cancer, it’s crucial to differentiate it. Our site also covers topics like sunburn and skin cancer and tretinoin versus other retinoids, giving you a broader view of skin health so you can recognize when a rash needs a specialist’s eye.

Treatment protocols hinge on the antiparasitic medication, single‑dose albendazole (400 mg) or a short course of ivermectin (200 µg/kg) that eradicates the larvae. Side effects are generally mild, but doctors monitor liver function if longer courses are required. After the drug clears the infection, supportive care – antihistamines like Zyrtec or topical steroids – eases itching. Prevention is just as important: always wear shoes on beaches, avoid standing barefoot on soil, and wash feet thoroughly after travel. These steps not only stop “creeping eruptions” but also reduce the risk of other parasitic skin infections.
