Myiasis is a common travel-associated dermatosis. Travelers to many parts of Central and South America are susceptible to infestation by Dermatobia hominis. Despite the common name of human botfly, D hominis infests a broad range of mammals and is a severe pest to economically important farm animals in endemic regions. The adult female does not lay the eggs on the host. Instead, the adult female infests hosts indirectly by using blood-feeding arthropods to serve as phoretic vectors to transport the eggs. We present a patient who acquired Dermatobia when bitten by a day-active mosquito during a visit to Guatemala. He had a locally painful, firm furuncular lesion with a central pore that drained serosanguineous exudates. The patient applied an occlusive ointment and recovered the larva after it emerged. In this report we discuss the life cycle of D hominis, the differential diagnosis, and therapeutic approaches.
蝇蛆病是一种常见的与旅行相关的皮肤病。前往中美洲和南美洲许多地区的旅行者易受人皮蝇（Dermatobia hominis）感染。尽管其俗名为人肤蝇，但人皮蝇会感染多种哺乳动物，并且在流行地区对经济上重要的农场动物来说是一种严重的害虫。成年雌性人皮蝇不会在宿主身上产卵。相反，成年雌性人皮蝇通过利用吸食血液的节肢动物作为携带卵的携播载体来间接感染宿主。我们报告一名患者，他在访问危地马拉期间被一只白天活动的蚊子叮咬后感染了人皮蝇。他有一个局部疼痛、坚硬的疖肿样病变，中央有一个小孔，排出血清样渗出物。患者涂抹了一种封闭性软膏，幼虫出现后将其取出。在本报告中，我们讨论了人皮蝇的生命周期、鉴别诊断和治疗方法。
