Myiases are parasitic infections by larvae of flies. The development of intercontinental travels increases the incidence of tropical myiasis in travellers. We report the case of a patient, having recently stayed in Peru, presenting with an inflammatory plate of the right shoulder, covered with small papules with a hole inside. The initial aspect seemed like an erysipelas. Considering the resistance to the antibiotic treatment, the diagnosis of myiase was suspected. The local application of petroleum jelly allowed the exit of nine larvae of Dermatobia hominis and a fast good outcome. In human beings, the number of larvae usually infecting the same individual varies from one to four. This observation is original because of the number of implied larvae, which explains the intensity and the extent of the local inflammatory signs, which first looked like erysipelas. This diagnosis must be suspected in cases of erysipelas resistant to antibiotics in patients back from an endemic area.
蝇蛆病是由蝇类幼虫引起的寄生虫感染。洲际旅行的发展增加了旅行者中热带蝇蛆病的发病率。我们报告一例患者，该患者近期曾在秘鲁停留，右肩部出现一个炎症性板块，上面覆盖着内部有孔的小丘疹。最初的表现类似丹毒。考虑到对抗生素治疗有抵抗，怀疑为蝇蛆病。局部涂抹凡士林后，排出了9条人肤蝇幼虫，且病情迅速好转。在人类中，通常感染同一个体的幼虫数量从1条到4条不等。该病例具有独特性，因其涉及的幼虫数量较多，这解释了最初看似丹毒的局部炎症体征的强度和范围。对于来自流行地区且对抗生素有抵抗的丹毒患者，必须怀疑这一诊断。
