ABSTRACT
La miasis forunculoide es una parasitosis producida por la larva de una mosca endémica en las regiones tropicales y subtropicales de América y África. Se presenta un caso de la enfermedad en un residente de Mendoza y una breve revisión bibliográfica de esta parasitosis, poco frecuente en Argentina.
Furuncular myiasis is a parasitosis infestation caused by fly larvae, it is endemic in the tropical and subtropical regions of America and Africa. We present a case in a patient living in Mendoza. A review of the literature regarding this uncommon parasitosis in Argentina is also presented here.

ABSTRACT Myiasis is a temporary infection of the skin or other organs with fly larvae.1 The larvae develop into boil-like lesions. Creeping sensations and pain are usually described by patients. Following the maturation of the larvae, spontaneous exiting and healing is experienced. Herein we present a case of a traveler returning from Central African Republic. She does not recall insect bites. She never took off her clothing for recreational bathing, nor did she visit any rural areas. The lesions appeared on unexposed skin. The specific diagnosis was performed by morphologic characterization of the larvae, resulting in Cordylobia anthropophaga, the dominant form of myiasis in Africa. To our knowledge, this is the first reported case of C. anthropophaga in Latin America.

La miasis es una infestación por larvas en desarrollo de una gran variedad de moscas del orden Díptera. Según el sitio de invasión, se clasifica en miasis cavitarias, que pueden deberse a invasión de cavidades naturales o de heridas, y miasis forunculoide, cuando atraviesa piel indemne. Esta infestación presenta una distribución mundial, con variaciones estacionales en relación con la latitud geográfica y el ciclo de vida de distintas especies de moscas. Presentamos una serie de tres casos de pacientes con distintas formas clínicas de manifestación de miasis. (AU)
Myiasis is the tissue infestation by a variety of Diptera order larvae flies. According to the invasion site, they are classified in myiasis of cavities, which can be because of an invasion of natural cavities or wounds, and furuncular myiasis, when they invade through intact skin. This infestation has a worldwide distribution, with seasonal variations in relation to the geographic latitude and the life cycle of different species of flies. We present three cases of patients with different clinical forms of presentation of myiasis. (AU)

A fly larva was recovered from a boil-like lesion on the left leg of a 33-year-old male on 21 November 2016. He has worked in an endemic area of myiasis, Uganda, for 8 months and returned to Korea on 11 November 2016. The larva was identified as Cordylobia anthropophaga by morphological features, including the body shape, size, anterior end, posterior spiracles, and pattern of spines on the body. Subsequent 28S rRNA gene sequencing showed 99.9% similarity (916/917 bp) with the partial 28S rRNA gene of C. anthropophaga. This is the first imported case of furuncular myiasis caused by C. anthropophaga in a Korean overseas traveler.

Las 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.
Cutaneous 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.

Abstract Furuncular myiasis is a parasitic infection caused by the larvae of Dipteran insects after penetrating healthy skin, causing an erythematous nodule with a central pore. Additionally, the patient may feel a sensation of movement and intermittent pain. Furuncular myiasis affecting the oral and perioral region is rare, usually leading to misdiagnosis. This paper describes a rare case of furuncular myiasis in a 20-year-old healthy male patient who presented an erythematous nodule in the lower lip. An exploratory surgery was indicated for both diagnostic and curative purposes, with successful healing observed in the following appointment. After 3 years of follow-up, the patient is recovered, with no clinical signs or symptoms of the disease.
Resumo A miíase furuncular é uma infecção parasitária causada pelas larvas de insetos Dipterans após penetrar na pele saudável, causando um nódulo eritematoso contendo um poro central. Adicionalmente, uma sensação de movimento e dor intermitente pode ser sentida. Miíase furuncular acometendo a região oral e perioral é rara, frequentemente causando erros diagnósticos. Este artigo descreve um caso raro de miíase furuncular em um paciente do sexo masculino de 20 anos de idade que apresentou um nódulo eritematoso no lábio inferior. Uma cirurgia exploratória foi indicada para fins diagnósticos e curativos, com sucesso observado já na sessão seguinte. Após 3 anos de acompanhamento, o paciente está recuperado, sem sinais clínicos ou sintomas da doença.

Myiasis is a parasitic infestation of vertebrate animal tissues due to maggots of two-winged flies (Diptera) that feed on living or necrotic tissue. Dermatobia hominis occurs widely in tropical parts of Latin America; it is the most common cause of furuncular myiasis in this region. The continuous increase in international travel has increased the possibility of observing this pathology outside endemic countries, especially in travelers returning from the tropics. If clinicians are aware of the possibility of the disease and its treatment options, this dermatosis can be easily managed. However, diagnostic delay is very common because the disease is often misdiagnosed as a bacterial skin infection. Here, we report 2 cases of furuncular myiasis caused by D. hominis in travelers returning to Italy from Latin America. Surgical and noninvasive treatment approaches are also described.

A case of furuncular myiasis was reported for the first time in a 29-year-old young Taiwanese traveler returning from an ecotourism in Peru. Furuncle-like lesions were observed on the top of his head and he complained of crawling sensations within his scalp. The invasive larva of botfly, Dermatobia hominis, was extruded from the furuncular lesion of the patient. Awareness of cutaneous myiasis for clinicians should be considered for a patient who has a furuncular lesion and has recently returned from a botfly-endemic area.

Myiasis is the infestation of any part of the body by Diptera larvae. It is the fourth most common travel-associated skin disease and cutaneous myiasis is the most frequently encountered clinical form. Furuncular lesions may result when the skin is affected. Cutaneous myiasis caused by Cordylobia anthropophaga has been endemic in the sub-Saharan African region for more than 135 years. There have been some reported cases from non-endemic regions, and yet C. anthropophaga infestations are rarely acquired outside of Africa. We report here a rare case of furuncular cutaneous myaisis by C. anthropophaga in a German patient who came to Korea after a three-week trip to Benin.
