Myiasis is the condition resulting from the invasion of tissues or organs of man or animals by dipterous larvae. The blowflies (Calliphoridae) of Argentina comprise several species that may cause myiasis by colonizing wounds or infected body orifices, and one specific parasite: Cochliomyia hominivorax. This species often causes traumatic myiasis in cattle, dogs and cats, and it is not rare in humans. The larvae consume living tissues, so they are dangerous unless speedily removed. Immediate operative exploration along with the removal of larvae and primary defect closure is recommended in every case. Here we report a case of myiasis in a scalp wound caused by blunt force trauma to the area, in a male patient with a case history of alcohol and drug abuse. Seventy-one living larvae were extracted from the wound and determined as C. hominivorax in the Forensic Entomology Laboratory. Given the aggressiveness of these larvae, specific and quick diagnosis as well as the application of appropriate treatment is crucial.
蝇蛆病是由双翅目幼虫侵入人或动物的组织或器官而引起的病症。阿根廷的丽蝇科（麻蝇科）包含几种可能通过在伤口或受感染的体腔中繁殖而导致蝇蛆病的物种，以及一种特定的寄生虫：嗜人锥蝇。该物种常引起牛、狗和猫的创伤性蝇蛆病，在人类中也并不罕见。幼虫会消耗活体组织，因此除非迅速清除，否则它们很危险。建议对每例病例都立即进行手术探查，并清除幼虫并缝合原发性伤口。在此，我们报告一例头皮伤口蝇蛆病病例，该伤口由该区域钝器外伤所致，患者为一名有酗酒和药物滥用病史的男性。在法医昆虫学实验室从伤口中提取了71条活幼虫，并鉴定为嗜人锥蝇。鉴于这些幼虫的侵袭性，进行特异性快速诊断并应用适当治疗至关重要。
