Tungiasis is a neglected ectoparasitism of impoverished areas in South America and sub-Saharan Africa. The sand flea Tunga spp. preferably infests the soles and the periungueal and interdigital regions of the feet. Ectopic tungiasis is rare, even in highly endemic areas. We describe a case of an indigenous patient in Peru who presented with a nodular lesion in the extensor aspect of the knee and whose biopsy was compatible with Tunga spp. This is the first documented case of knee tungiasis in an endemic country. The historical, clinical, histological, and current epidemiological aspects of tungiasis in Peru are discussed here.
疥疮是南美的贫困地区和撒哈拉以南非洲地区被忽视的外寄生虫病。沙蚤 Tunga spp. 更喜欢在脚底、甲周和趾间区域寄生。即使在高度流行的地区，异位疥疮也很少见。我们描述了秘鲁的一位土著患者，他的膝盖伸侧出现了结节性病变，其活检结果与 Tunga spp. 相符。这是在流行国家首例记录在案的膝盖疥疮病例。本文讨论了秘鲁疥疮的历史、临床、组织学和当前流行病学方面。
