Furuncular myiasis occurs after larvae penetrate on the skin. The disease is characterized by the presence of a nodule with a central hole through which there is serosanguinous exudate drainage. The authors present a case of furuncular myiasis by Dermatobia hominis in which late diagnosis made it necessary to have the orifice margins surgically enlarged in order to extract the larva. They also emphasize that dermoscopy is a useful auxiliary tool in this diagnosis.

“…The period of incubation is less than 24 hours, which makes it possible to find fully grown larvae that cause significant tissue destruction within a few days of infestation and the presence of hundreds of maggots in a single wound . Dermoscopy has proven useful in diagnosing many infections, such as scabies, pediculosis and molluscum contagiosum, and furuncular myiasis caused by larvae of Dermatobia hominis , and, as in the present case, wound myiasis caused by C. hominivorax . The poor living conditions and associated pediculosis in our patient indicate increased risk for a double infestation.…”

ResumenLas lesiones cutáneas son causa frecuente de consulta en viajeros siendo las picaduras de insectos unas de las más prevalentes. Damos a conocer un caso de paciente que presenta una lesión dolorosa en cuero cabelludo, tras viaje a la selva boliviana, refractario a tratamiento antibiótico empírico y con estudio complementario inconcluyente. Finalmente, se realizó estudio macroscópico de la costra, que determinó que se trataba de una larva de Dermatobia Hominis. Este caso demuestra la importancia de tomar en cuenta estos agentes no presentes en Chile y que son causantes de patologías dermatológicas del viajero.Palabras claves: miasis foruncular; dermatobia hominis; viajero. summaRyCutaneous lesions are frequent cause of consultation in travelers, being insect bites one of the most prevalent. We present a case of a patient with a painful lesion on the scalp, after a trip to the Bolivian jungle, refractory to empirical antibiotic treatment and with an inconclusive complementary study. Finally, macroscopic study of the crust was carried out, which determined that it was a larva of Dermatobia Hominis. This case demonstrates the importance of taking into account these agents not present in Chile and that are the cause of dermatological pathologies of the traveler. Las miasis cutáneas corresponden a la colonización de la piel por larvas de díptero; son procesos de distribución mundial con mayor incidencia en zonas tropicales.2 En nuestro medio son poco frecuentes y se suelen observar predominantemente en turistas e inmigrantes.Existen tres formas clínicas: la miasis sobre heridas, migratoria y foruncular.3 La presentación más frecuente de miasis es la miasis foruncular causada por Dermatobia hominis en viajeros hacia América Central y del Sur, y Cordylobia anthropophaga en viajeros a África, las cuales, a través de un vector dejan sus larvas en tejido subcutáneo para su desarrollo y crecimiento. 4 En el siguiente artículo se revisa un caso de un paciente de sexo masculino quien posterior a un viaje a la selva boliviana consulta por lesión en cuero cabelludo. Tras estudio con ecografía de partes blandas y biopsia inconcluyentes, finalmente se llegó a la conclusión de que se trataba de un caso de miasis por D. hominis a través del examen macroscópico de la costra.
