Cutaneous furuncular myiasis: Human infestation by the botfly
1Section of Plastic Surgery, Department of Surgery, The University of Michigan, Ann Arbor, Michigan, USA.
Summary
Human botfly (Dermatobia hominis) infestation causes rare skin lesions. Misdiagnosis is common due to similar symptoms to other conditions, highlighting the need for broader differential diagnoses.
Area of Science:
- Medical Entomology
- Dermatology
- Tropical Medicine
Background:
- Dermatobia hominis, the botfly, is endemic to Central and South America.
- Mammals, such as horses and cows, are the typical hosts for this parasite.
Observation:
- Cutaneous furuncular myiasis is a rare condition of human infestation by the botfly.
- Infestation presents as a painful, firm, furuncular skin lesion with a central pore.
Findings:
- Botfly lesions are frequently misdiagnosed due to overlapping symptoms with cellulitis, leishmaniasis, furunculosis, boils, insect bites, or cysts.
- The infrequent nature of this parasitic infestation contributes to diagnostic challenges.
Implications:
- This case underscores the importance of considering rare tropical diseases in differential diagnoses, especially in endemic regions.
- Clinicians should maintain a high index of suspicion for myiasis when encountering unexplained furuncular lesions.
- Prompt and accurate diagnosis is crucial to prevent complications and ensure appropriate treatment for cutaneous myiasis.

01:23Skin Diseases and Disorders
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

01:22American Trypanosomiasis
Chagas disease, or American trypanosomiasis, is a vector-borne parasitic infection caused by Trypanosoma cruzi, a flagellated protozoan (kinetoplastid) of the family Trypanosomatidae. The disease is endemic in Latin America, although cases are increasingly reported worldwide due to human migration. Transmission most commonly occurs when feces of infected triatomine bugs contaminate bite wounds or mucosal surfaces; additional routes include congenital, transfusional, transplant-related, and oral...
01:30Leishmaniasis
Leishmaniasis is a protozoal disease caused by species of the genus Leishmania and transmitted through the bite of infected female sandflies. The parasite exists in two principal morphological forms during its life cycle. A sandfly acquires intracellular amastigotes from an infected reservoir host, such as a dog. Within the sandfly, these forms differentiate into motile, flagellated promastigotes. During a subsequent blood meal, promastigotes are injected into the human host, where they...
01:16Accessory Structures of the Skin: Hair and Hair Follicles
Hair and hair follicles are integral components of the integumentary system. Hair is a filamentous structure composed mainly of a protein called keratin. It is found on the surface of the skin throughout the body, except for areas such as the palms of the hands and soles of the feet.
Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...

01:27Acne Infection
Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...
01:28Fungal Phylum Microsporidia
Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...
