An Itch on the Move: A Diagnostic Dilemma of Cutaneous Serpiginous Eruption

Cutaneous larva migrans is a common parasitic dermatosis, typically affecting the feet and lower extremities, but involvement of atypical anatomical sites may lead to diagnostic delay. We report a 40-year-old woman who presented with an intensely pruritic, migratory serpiginous eruption that sequentially involved the ear, neck, shoulder, and scapular region over one month. A detailed exposure history, characteristic migratory morphology, and supportive dermoscopic findings established the diagnosis of cutaneous larva migrans. The patient responded well to systemic albendazole with adjunctive topical ivermectin. This case highlights that cutaneous larva migrans should be kept in the differential of a creeping migratory lesion irrespective of site.
