Abstract
AVENDANO, CA Niño; RODRIGUEZ, LJ Vargas and LEON, AM Chacón. Cutaneouslarva migrans: clinical case. Rev. argent. dermatol. [online]. 2020, vol.101, n.4, pp.111-120. ISSN 1851-300X.
Introduction:
The cutaneous migratory larvae, also known as emigrant myiasis, is a dermatological entity produced by the penetration of Helminths to the skin.
Case:
53-year-old male, who consulted for 5 days of evolution of lesions in the limbs of the erythematous and pruritic type, of progressive growth, which began as small papules with a diameter of 0.5 cm and subsequently increased in size approximately 2.5 cm in length. It was considered that he was studying cutaneous larva migrans, due to his symptoms and exposure to risk factors.
Conclusions:
The prevalence in the countries of South America varies between 0.2 and 4.4% in the general population and reaches up to 14% in children under 5 years of age. The diagnosis of larva migrans is fundamentally clinical, according to the evidence of skin lesions with typical serpeginous lesions, and very itchy. These are located in areas where the thickness of the skin is thinner. An anamnesis aimed at asking the patient about the different risk factors will help us to establish the diagnosis. Ivermectin treatment is highly effective.
