Abstract

Background: Myiasis refers to the infection of vertebrate tissues by dipteran fly maggots. The most well-known causal organism is Dermatobia hominis, a human botfly. 
Case presentation: A 24-year-old female residing in Asmara, Eritrea, presented herself at the emergency room after experiencing a foreign body sensation for six days, with a history of multiple painful and pruritic nodules on 8th September 2025 at Halibet Referral Hospital. She found 7 erythematous, tender nodules and noticed a sensation of movement over the nodules, with a small central punctum appearing on the patient’s extremities. Although she had not traveled internationally, she recently visited a family member on the 10th of July 2025 in the Southwest region of Eritrea. On her clinical examination, she had multiple areas of furuncular lesions with visible moving larvae. After applying petroleum jelly to every patient's lesion, every visible larva was successfully extracted by forceps. The patient was prescribed a seven-day course of an oral antibiotic combination: Amoxicillin trihydrate 500 mg and clavulanic acid (as potassium clavulanate 125 mg), administered three times a day for seven days. The follow-up confirms, the patient has successfully recovered from myiasis. 
Conclusion: In most cases, myiasis is an illness that both patients and medical professionals find repulsive and unpleasant. In order to compare various therapy modalities, validate treatment procedures, and improve diagnostic methods, future research should try to cover a wider spectrum of cases.

Introduction

Myiasis is defined as the parasitic infection of live vertebrate hosts-both humans and animals-by dipteran fly larvae (maggots) [1,2]. These flies deposit their eggs or larvae into bodily cavities or wounded skin, and the larvae subsequently penetrate and feed on live or necrotic tissue and bodily fluids [3]. The duration spent within the host varies by species before the larvae exit to pupate [3].
The most widely recognized causative agent worldwide is the human botfly, Dermatobia hominis [4]. However, the most prevalent clinical manifestation, furuncular myiasis, is endemic to specific geographic regions: Africa [5,6] and Latin America [6]. The occurrence of myiasis varies geographically and seasonally [7]. 
The frequency of infestation correlates strongly with latitude and the specific life cycle of the causative fly species [7]. Myiasis is categorized into three types based on the host-parasite relationship: obligatory (tropical in origin), facultative [2], and accidental [8]. Although obligatory forms are widespread, accidental and facultative types are rare globally. Notably, very few official case reports have emerged from the Horn of Africa region [9]. Several common risk factors predispose individuals to infestation, including tropical climates, unhygienic environments, low socioeconomic status, close animal contact, compromised immune systems, and inadequate wound care [2,10,11]. Beyond localized tissue destruction, myiasis infestations can trigger inflammatory and allergic reactions [12]. While cutaneous infections are most common, larvae can also infest sensitive areas such as the eyes, ears, and respiratory system [13–15]. 
Despite its endemic presence across the continent, significant epidemiological gaps exist in the Horn of Africa region, with very few official case reports emerging from this specific area [9]. This lack of published data translates into substantial clinical challenges in diagnosis, as myiasis remains an unfamiliar and largely underestimated condition among local Eritrean healthcare workers. Compounding this, presentations that deviate from typical furuncular myiasis can be easily misdiagnosed as routine bacterial infections, delaying appropriate management. This knowledge deficit poses a public health significance, hindering effective surveillance and community education efforts in high-risk populations. This article addresses these critical gaps by describing an uncommon presentation of multiple furuncular myiasis in a young female patient from Eritrea.

Case Presentation

On September 8, 2025, a 24-year-old female from Asmara, Eritrea, went to the emergency room at Halibet Referral Hospital after suffering a foreign body sensation for six days and having a history of many painful and pruritic nodules. The patient was transferred to the parasitology department. She found 7 erythematous tender nodules and noticed a sensation of movement over the nodules with a small central punctum appearing on the patient’s extremities (legs and arms). She also claims that an insect-like worm comes out of the lesion site and a small portion of the larva was visible to her naked eye in other nodules.
Although she had not traveled internationally, she recently visited a family member on the 10th of July 2025 in the Southwest region of Eritrea, Mai Dma. On her visit, she remembered that there was an insect bite on her extremities. On her clinical examination, she had multiple areas of furuncular lesions (Figure 1a, c, and d), the posterior of a larva was visible (Figure 1a), and started to extract. At this point, the patient requested the excision of all larvae. However, extraction may result in tissue trauma, a significant inflammatory reaction if the larva is mangled and not completely removed, and subsequent infection. As a result, we advised this patient to apply petroleum jelly to all lesions and return two days later for the extraction of any residual larvae. As shown in Figure 1e, all visible larvae were extracted by forceps. The patient was prescribed a seven-day course of an oral antibiotic combination: Amoxicillin trihydrate 500 mg and clavulanic acid (as potassium clavulanate 125 mg), administered three times a day for seven days. The follow-up confirms, the patient has successfully recovered from myiasis, the infection has been treated, and her health is in good shape.

Discussion

In most cases, myiasis is an illness that both patients and medical professionals find repulsive and unpleasant. Although myiasis is endemic in Latin America and Sub-Saharan Africa, cases are generally thought to be underreported because of a lack of entomological knowledge, low physician awareness, and inadequate diagnostic resources in some regions. The majority of cases that are documented are "imported" by tourists who are returning from endemic areas, mainly Latin America and Sub-Saharan Africa. According to one assessment, 122 (77.7%) of the 157 cases associated with SSA were reported from non-African nations (such as Europe, North America, and Asia) after tourists returned home [16]. According to our case report, furuncular myiasis is the most prevalent presentation in Africa and the most often reported form among returning travellers globally [17].
Open wounds, immunocompromised people, those from low socioeconomic backgrounds, those who are homeless, and drug addicts are risk factors [2,9,10]. Myiasis manifests as painful nodules, typically with central puncta, as well as pain, nocturnal pruritus, or overall discomfort in the skin surrounding the location, as previously reported [18]. Furuncular myiasis patients frequently exhibit redness, skin irritation, itching, and a crawling feeling beneath their skin [2]. Our patient experienced discomfort, tingling and pruritus among these symptoms. Furuncular myiasis differs from cutaneous larva migrans, cellulitis, and furuncles primarily in its etiology and presentation. While myiasis involves a motile fly larva causing a localized, painful boil-like lesion, cutaneous larva migrans features a migrating parasitic track without a static boil. In contrast, both cellulitis and furuncles are bacterial infections, presenting as a spreading, non-migratory rash (cellulitis) or a static, pus-filled nodule (furuncle), all of which lack the unique, contained larval movement seen in furuncular myiasis. 
Furuncular myiasis typically resolves on its own. As demonstrated in this instance, the gold standard for treating myiasis still consists of larval removal, surgical debridement [19], antibiotics, and topical or oral ivermectin treatment [9]. Effective myiasis treatment and prevention involve several critical steps rooted in medical and entomological consensus. Clinicians should consider administering a tetanus vaccine if the patient is not already advised or properly immunized according to the current guidelines of the Centers for Disease Control and Prevention [20]. The extraction of the complete larva is crucial for successful management, as harming the larva can result in a severe inflammatory reaction, bacterial infection, or granuloma formation from retained parts [9,21]. A more advanced stage of the larva facilitates extraction [9]. The removal process can sometimes be facilitated in a more advanced larval stage by using suffocating agents like petroleum jelly or liquid paraffin, which cause the larva to collapse its spines as it seeks air [20]. Secondary bacterial infections must also be treated, and proper hygiene must be encouraged. The positive result emphasizes how crucial it is to maintain wound care and follow up regularly in order to avoid reinfestations or other problems in the future. 
Preventive strategies in endemic areas include simple hygiene practices like keeping clothes off the ground, hanging them in the sun or indoors with closed windows, and ironing them before wearing them to destroy any potential eggs [9]. To the best of our knowledge, this is the first instance of myiasis in Eritrea. Using the phrases "Eritrea," "myiasis," "cutaneous myiasis," and "furuncular myiasis," an advanced PubMed search yielded no results related to myiasis. Furuncular myiasis cases are underreported in Eritrea and maybe the Horn of Africa.

Conclusions

It is easy to misdiagnose furuncular myiasis for cellulitis or furunculosis. Dermatologists and other medical professionals need to understand management and clinical characteristics. Public education about the importance of receiving care from a skilled health care provider may help avert issues, particularly among the elderly and those at high risk of infection. Myiasis should be added to the list of diseases to report, and entomological identification of the larval species that causes it should be done on a regular basis. In light of this, this report could aid in underreported cases of myiasis, in administering the proper care, and in enhancing our comprehension of such situations. In order to compare various therapy modalities, validate treatment procedures, and improve diagnostic methods, future research should try to cover a wider spectrum of cases.
