摘要

寄生虫病的皮肤表现多种多样,并与各种机制有关。当寄生虫位于接种部位时(利什曼原虫属),在真皮中(钩虫属),活在皮肤或头发上时(体外寄生虫),主要通过直接检查进行诊断。聚合酶链式反应(PCR)是皮肤利什曼原虫病的一种明智的诊断方法,可以快速识别致病物种。寄生虫病的其他皮肤症状是一般的过敏表现。在这种情况下,必须根据临床和流行病学数据来选择具体的需求。在某些蠕虫病(旋毛虫、血吸虫病、筋膜炎)的侵袭期或内脏幼虫迁移期(毒虫病),过敏反应尤其强烈。在这些病例中,寄生虫学诊断依赖于血清学检测。

Prélèvements parasitologiques en dermatologie

Cutaneous manifestations of parasitosis are numerous and related to various mechanisms. When parasites are located at the inoculation site (Leishmania spp), in dermis (Onchocerca volvulus), live on skin or hair (ectoparasites) diagnosis is mainly made by direct examination. PCR (polymerase chain reaction) is a sensible diagnostic method for cutaneous leishmaniaisis and allows a rapid identification of causative species. Other cutaneous symptoms of parasitosis are general allergic manifestations. In this case, specific demands must be selected after clinical and epidemiological data. Allergic reactions are particularly intense during the invasive stage of some helminthiasis (trichinellosis, schistosomiasis, fasciolasis) or in visceral larva migrans (toxocariasis). In these cases, the parasitologic diagnosis relies on serologic assays.
