Ultrasound features of cutaneous myiasis: a rare case in a child.

Cutaneous myiasis is an infestation of the skin with larvae of some dipteran species. Among humans, Dermatobia hominis is the most frequently encountered dipteran responsible for cutaneous myiasis. This insect is endemic to tropical and subtropical regions, consequently, individuals travelling from non-endemic areas are most susceptible to infection due to a lack of prior exposure. Three clinical variants of myiasis are distinguished: furuncular, migratory, and wound myiasis. Furuncular myiasis represents the most common form among travelers, yet it is a rare cause of pediatric skin manifestations in developed countries. Limited awareness of this condition in non-endemic regions contributes to diagnostic challenges. In this scenario, ultrasound is useful in the diagnostic workup, enabling the identification of the viable larva.

Furuncular myiasis caused by Dermatobia hominis: entodermoscopic findings.

A 27-year-old male traveller returning from the Amazon forest came to our dermatology consultation with a furuncle-like nodule in the temporal region. During examination we observed an erythematous nodule with a central opening. We describe the entodermoscopic characteristics of Dermatobia hominis.

Cutaneous Furuncular Myiasis in a Rural Kenyan Hospital: A Case Report

Myiasis is a neglected tropical disease caused by infestation by the larval stages (maggots) of many species of flies, which occur worldwide but are more prevalent in the tropical and subtropical regions. The two main types of flies causing human myiasis are Dermatobia hominis (bot fly) and Cordylobia anthropophaga (tumbu fly). Cases of human myiasis in Kenya are not well documented, but some epidemiological studies show the tumbu fly to be the most prevalent. Transmission and infestation occur in cases of poor personal and environmental hygiene, especially in spaces shared with wild and domestic animals. Cutaneous myiasis, presenting as a furuncular, wound, and migratory disease, is the most common clinical phenotype that may be associated with secondary pyogenic infection and cellulitis, especially when not treated promptly. In this study, we present a case of cutaneous furuncular myiasis in a patient from rural Kenya. We share our experience managing the patient and also provide a literature review on the clinical case management of myiasis, with a call for more epidemiological and clinical work to be done to better understand this neglected disease.

Furuncular myiasis in a pediatric outpatient clinic in Enugu, South-Eastern Nigeria

Myiasis has been associated with poor standards of hygiene in children, particularly in sub-Saharan Africa. In our practice, however, we encountered cases of myiasis in children from high socioeconomic backgrounds. Four cases of myiasis were reported in children aged between 20 months and 7 years, all belonging to the upper socio-economic class. Spreading clothes inside-out on clothesline and shrubs was a major risk factor. We concluded that there is a need for the enlightenment of the public as regards this disease condition, even among the upper class.

Furuncular cutaneous myiasis in Saudi Arabia

Myiasis is the infestation of a living vertebrate by a fly's larva, completing its obligate life cycle. Exposed skin remains the most affected site. The botfly, Dermatobia hominis , is the most common cause of cutaneous furuncular myiasis in tropical areas. Few cases have been reported in Saudi Arabia, mainly in the Southern region. A one-year-old medically free child presented to our pediatric surgery clinic with a painful, itchy discharging nodule on the inner aspect of his right forearm for one-week. The patient's mother and sibling had a similar former presentation after visiting Taif city. We dilated the central punctum and extracted the larva fully intact. The larva was identified morphologically as Dermatobia hominis by a parasitologist. The lesion was left to heal secondarily, which resulted in an acceptable cosmetic result and minimal scarring. Raising this clinical entity's awareness between pediatric surgeons will set aside misdiagnosis, delayed management, and possible complications. A high level of suspicion and careful history taking are required to recognize myiasis, particularly in patients with a recent history of global traveling or those with close contact with cattle.

610 A Case Report of Furuncular Myiasis Affecting the Glans Penis of a Young Boy Caused by the Larvae of Cordylobia Anthropophaga (The Tumbu Fly)

Abstract Introduction Cutaneous myiasis is endemic in West Africa, and it is most commonly caused by the larvae of Cordylobia anthropophagia. In English literature, there has been no recorded case of this cutaneous myiasis affecting the glans penis. Its rarity calls for a need to consider this as a differential when looking at furuncular lesions of the glans penis. This awareness is important for practitioners who may come across this case. We report a case of furuncular myiasis of the glans penis due to the larvae of C.anthropophaga of an 11-year-old boy living in Lagos, Nigeria. Case presentation We present an 11-year-old boy who presented to the surgical department with a lesion on his glans penis, initially thought to be a boil. Upon examination, the lesion contained a single larva of C.anthropophaga. It was extracted in the minor theatre with a non-toothed forceps, and the area healed well following discharge. (Pictures of extracted larvae are available upon request). Discussion Although endemic, furuncular myiasis of the glans penis is a very rare condition, likely related to the living circumstance of the patient. An awareness of the clinical features is important so as to prevent misdiagnoses of foruncular lesions that occur on the glans penis, especially in people with identified risk factors. Health education and promotion of good hygiene are important in reducing the incidence of Cordylobia anthropophagia infestation.

Myiasis by Cordylobia anthropophaga (Calliphoridae) in rodents from Cape Verde

PurposeThe tumbu fly, Cordylobia anthropophaga (Diptera: Calliphoridae), is widely distributed in continental tropical and subtropical Africa, being the most common cause of furuncular myiasis in Sub-Saharan Africa. The aim of the present work was to analyze the role of rodents as possible reservoirs of C. anthropophaga in Cape Verde, considering the zoonotic character of this fly species.Materials and MethodsA total of 150 peridomestic rodents were studied in Santiago island. For the obtained larvae, morphological and molecular characters were analyzed.ResultsCordylobia anthropophaga was found in 6.4% of the peridomestic Rattus rattus analyzed. The present work unveils the presence of C. anthropophaga in rodents of the African archipelago of Cape Verde, introduced probably with West African humans and/or animals.ConclusionThe presence in peridomestic animals, and the wide range of species that this fly can affect, entails a zoonotic risk of myiasis by tumbu fly.

Furuncular myiasis by Wohlfahrtia magnifica (Diptera: Sarcophagidae) in a healthy child

Rationale: Human myiasis is the invasion of tissue or organs by fly larvae. This could be obligatory, facultative, or accidental.Patient concerns: A 4-year-old Saudi boy complained of fever over the past three days with multiple inflamed painful dermal furuncles and worms-like discharge.Diagnosis: Furuncular obligatory myiasis caused by Wohlfahrtia magnifica.Interventions: Maggots were removed for identification. The wounds were cleaned with antiseptic dressings. Topical and oral antibiotics were applied.Outcomes: Seven days later, the wounds completely healed.Lessons: Although several reports correlated human myiasis with old age, low health status, mental retardation, and low socioeconomic status, but the patient in our case was a healthy child from a family with good socioeconomic status, good hygiene, no history of diseases or mental disability, but traveled to a village where the climate is suitable for fly breeding.

Cutaneous myiasis (Cordylobia Anthropophaga): An interesting case report of a patient returning back from Central Africa

Myiasis is a disease caused by the larvae of Diptera flies infesting living tissue. The most common type of myiasis is cutaneous involvement. Imported infections are becoming more common as a result of international travel to tropical regions. After a 3 month stay in Congo, a 29-year-old developed furuncular myiasis on returning to India.

Childhood Furuncular Cutaneous Myiasis Associated with Seborrheic Dermatitis: A Case Report

Myiasis is a parasitic infection caused by dipterous fly larvae that can affect various organs in both human and animals. Cutaneous myiasis is the most common type of myiasis and can be classified into three categories, localized furuncular myiasis, migratory myiasis, and wound myiasis. One of the risk factors for myiasis is seborrheic dermatitis. The definitive treatment for the condition requires complete extraction of larvae, in combination with oral therapy, and localized occlusion to promote hypoxia. This paper reports a case of a 12-year-old girl with furuncular cutaneous myiasis associated with seborrheic dermatitis on the occipital region that showed significant improvements after manual extraction of larvae after local anesthesia injection of 2% lidocaine on the base of the lesion, in combination with oral and topical therapies

Effectiveness of sarolaner in the clinical management of furuncular myiasis in dogs naturally infested with Dermatobia hominis (Diptera: Cuterebridae)

BackgroundThe human botfly, Dermatobia hominis, is a common cause of furuncular myiasis in dogs in Latin America. Lesions can be single or multiple, each harboring an individual larva, presented as an erythematous nodule that causes pruritus and pain. Typical treatment consists of sedation for removal of larvae by surgical incision or manual pressure. Medications to kill the larva before its extraction can reduce inflammation and discomfort and provide a less traumatic larval removal. Isoxazolines are broad-spectrum ectoparasiticides with larvicidal activity previously reported in the treatment of screwworm myiasis in companion animals. The aim of this study was to evaluate the effectiveness of sarolaner as part of the clinical management of furuncular myiasis in dogs caused by D. hominis larvae.MethodsTen short-haired mixed breed dogs naturally infested with D. hominis were enrolled. Clinical diagnosis was achieved by observation of skin nodules and visualization of larval motility through the lesion orifice. Sarolaner was administered at manufacturer recommended dose for fleas and ticks. Lesions were reexamined 24 h post-treatment and assessed for viability of larvae. Larvae were removed by digital compression and identified as D. hominis.ResultsSeventy-five D. hominis larvae were retrieved from ten dogs. No live larvae were observed, demonstrating 100% larvicidal efficacy of sarolaner. Skin lesions were healed 30 days post-treatment and new lesions were not observed.ConclusionsSarolaner seems to be effective as larvicidal treatment for dogs with furuncular myiasis, reducing discomfort caused by the presence of the larva in the skin and facilitating its safe removal.Graphical abstract
