Résumé
La tungiasis es una ectoparasitosis causada por la penetración en la piel de la pulga hembra Tunga penetrans. Esta enfermedad no es específica del hombre y se distribuye en regiones cálidas y secas alrededor del mundo. Se adquiere por contacto directo con el suelo en donde habitan los parásitos adultos. En zonas endémicas, su alta prevalencia se asocia a pobreza y falta de acceso al sistema de salud. Además es frecuente entre viajeros que visitan regiones endémicas y que regresan a sus lugares de origen. Presentamos un caso típico de tungiasis en un paciente 39 años que había realizado un viaje reciente a zona endémica. (AU)
Tungiasis is an ectoparasitosis caused by penetration into the skin of the female flea Tunga penetrans. This disease is not human-specific and is distributed worldwide in warm, dry regions. It is acquired by direct contact with the soil where the adult parasites live. In endemic areas, its high prevalence is associated with poverty and lack of access to the health system. It is also frequent among travelers visiting endemic regions and returning to their places of origin. We present a typical case of tungiasis in a 39 year old patient who had made a recent trip to an endemic area. (AU)

The female flea Tunga penetrans is responsible for a cutaneous parasitosis known as Tungiasis. We report the clinical case of a 12 year-old Caucasian boy who sought treatment in a dermatological private office due to a painful lesion in the plantar area and whose dermoscopic examination, without skin contact, allowed the visualization of parasite's movement inside the skin. The diagnosis of tungiasis is clinical, but it can be aided by in vivo and ex vivo dermoscopic examination of the lesion.
A fêmea da pulga Tunga penetrans é responsável pela dermatose ectoparasitária denominada Tungíase. Relatamos o caso clínico de um adolescente branco de 12 anos de idade, o qual procurou atendimento em consultório dermatológico devido à lesão dolorosa na planta e cujo exame dermatoscópico sem contato com a pele permitiu visualizar o movimento do parasita dentro da pele. O diagnóstico da tungíase é clínico, porém pode ser auxiliado pelo exame dermatoscópico in vivo e ex vivo da lesão.
