A 42-year-old male presented with itchy papular lesions all over the back which progressed over five days [Figure 1]. The patient gave a history of sleeping on the beach sand. With the history and clinical findings, a diagnosis of cutaneous larva migrans (CLM) was made. CLM is a pruritic migrating skin eruption commonly caused by animal hookworms, namely Ancylostoma braziliense, Ancylostoma caninum, and Uncinaria stenocephala. CLM usually presents as an itchy papular rash that is characteristically migratory. It moves slowly by a few millimeters to 2 cm per day, differentiating it from other migratory skin lesions. Localized lesions are treated with thiobendazole 15% cream. Multiple or generalized lesions may be treated with a single dose of ivermectin (200 mcg/kg) or albendazole 400 mg daily for 3-5 days. Complete resolution is seen in a few days. Secondary bacterial infections, eczematous changes, Loeffler’s syndrome are some of the complications that may be noticed in untreated individuals.[1]
