Abraham LS(1), Azulay-Abulafia L, Aguiar Dde P, Torres F, Argenziano G. We describe a 56-year-old Brazilian woman presenting three nodular lesions on the scalp. Dermoscopy of all lesions showed a creamy-white body with central bird's feet-like structures surrounded by a thorn. A 39-year-old man who was returning from the Amazon Jungle and had no medical history presented with a furuncular lesion on his right parietal scalp. Despite receiving appropriate antimicrobial treatment, his lesion did not heal. After surgical intervention, a Dermatobia hominis larva was extracted. A child is presented with cutaneous myiasis that presented as furuncle-like nodules on the scalp. The larvae were identified as a stage of the bluebottle-like fly, Dermatobia hominis. Myiasis is the infestation of body tissues of humans and animals by the larvae of Diptera [ 1 ]

Cutaneous furancular myiasis caused by D. hominispresents as inflamed cystic nodules, all of which have a well-circumscribed central pore.11Lesions are commonly found on exposed areas of the skin, such as the scalp and the upper and lower limbs. The furancular nodules often have an accompanying exudate Cutaneous myiasis is myiasis affecting the skin. Myiasis can be categorised clinically based on the area of the body infested, for example cutaneous, ophthalmic, auricular, and urogenital. Cutaneous presentations include furuncular, migratory, and wound myiasis, depending on the type of infesting larvae Typical symptoms of furuncular myiasis include itching, a sensation of movement, and sometimes sharp, stabbing pain. At first, people have a small red bump that may resemble a common insect bite or the beginning of a pimple (furuncle). Later, the bump enlarges, and a small opening may be visible at the center Furuncular myiasis caused by rodent or rabbit botflies, Cuterebra spp., may present as subcutaneous abscesses on the face, scalp, neck, shoulders or chest (Shorter et al)

Necrotic edges of the ulcer were excised and extended in a cruciate fashion (Figure 1b). Wound was thoroughly washed with pyodine, and duly diluted with normal saline Myiasis is defined as the infestation of live vertebrates (humans and/or animals) with dipterous larvae. In mammals (including humans), dipterous larvae can feed on the host's living or dead tissue, liquid body substance, or ingested food and cause a broad range of infestations depending on the body location and the relationship of the larvae with the host Key words: Dermatobia hominis, furuncular myiasis, human botfly, phoresis, foreign travel, cutaneous myiasis Introduction A 19-year-oldmale college student presented six weeks after foreign travel; he was experiencing a pruritic, nonheal­ ing, intermittently painful, draining lesion of the anterior scalp which was resistant to antimicrobial. 1.1 Background:Myiasis is caused by the invasion of tissues or organs of man or animals by dipterous larvae. A four-year-old girl presented with one month history of scalp ulcer that has initially started as a painful itchy swelling in the occipital region. Physical examination revealed live maggots in the ulcerous wound. The maggots were identified as the third instar larvae of Wohlfahrtia.
