Abstract
Background: Cutaneous larva migrans (CLM) is a parasitic infection caused by the accidental penetration of canine hookworm larvae into the superficial layers of human skin. Although typically self-limiting, delayed diagnosis may result in complications such as secondary infections or allergic reactions.
Case Presentation: The case involved a 54-year-old man with a history of hypertension who presented with a creeping, erythematous lesion on his left leg, accompanied by severe pruritus and a history of contact with a pet dog. After confirming the dog’s hookworm infection and conducting further clinical evaluation, a diagnosis of CLM was established. Treatment with albendazole and an antihistamine resulted in complete resolution of the patient’s symptoms.
Conclusion: Although CLM is typically a self-limiting condition, timely initiation of treatment can significantly reduce the duration and severity of symptoms. The growing trend of pet ownership has increased the risk of CLM transmission, underscoring the importance of implementing effective preventive measures.
