Background
- Also known as creeping eruption or sandworm disease[1]
- Caused by movement of hookworm larvae through epidermis[2]
- Ancylostoma caninum and Ancylostoma braziliense are most common pathogens
- Typically occurs due to contact with dog/cat feces in soil/sand
- More common in warm/tropical areas
- History is typically of a patient sunbathing, walking on the beach, etc in a tropical environment[1]
Clinical Features
- Pruritis serpiginous eruption[2]
- Pruritis can be intense[1]
- Usually unilateral, but can be bilateral
Differential Diagnosis
- Papules
- Insect bites

Diagnosis
- Clinical diagnosis, based on history and physical exam
Management
- Self-limited condition - larvae die within 2-8 weeks[2]
- Albendazole 400mg PO QD x3-5 days OR Ivermectin 12mg PO x1 OR topical thiabendazole TID x15 days
Disposition
