RT Journal Article SR Electronic T1 Dermatobia hominis ‘the human botfly’ presenting as a scalp lesion JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e228310 DO 10.1136/bcr-2018-228310 VO 12 IS 3 A1 Louise Dunphy A1 Vikas Sood YR 2019 UL http://casereports.bmj.com/content/12/3/e228310.abstract AB Owing to increasing international travel, physicians will encounter more infectious diseases acquired overseas, which may be bacterial, fungal or parasitic in nature.1 Knowledge of the geographic distribution of specific diseases permits the formulation of a differential diagnosis in the context of clinical presentation. Parasitic infestations of the maxillofacial tissues can be caused by a host of different ectoparasites, for example, myiasis, a frequently misdiagnosed disease of tourists returning from exotic locations. For those natives and travellers who are subject to these ‘infestations’, the experience can be both alarming and very distressing.
