IntroductionCutaneous larva migrans (CLM) is caused by the larvae of hookworms that infect dogs and cats, most commonly Ancylostoma braziliense and Ancylostoma caninum, and less frequently Necator americanus, Uncinaria stenocephala, and Strongyloides stercoralis.¹ These larvae are typically found in warm, moist soil or sand contaminated with animal feces and are prevalent in tropical and subtropical climates. Human infection occurs when larvae penetrate intact skin, most often on the feet or legs.Once inside the epidermis, the larvae migrate, forming winding, erythematous, intensely pruritic tracks known as “creeping eruption.”² The incubation period ranges from a few days to several weeks. Early lesions may present as pruritic papules or plaques resembling eczema or insect bites, leading to misdiagnosis in up to 58% of cases.³ Topical corticosteroids are frequently prescribed but do not eliminate the larvae and may delay appropriate treatment.⁴
