Human myiasis, the infestation of tissues by dipterous larvae, commonly manifests as painful, raised skin lesions, particularly in tropical regions such as Latin America, where (the human botfly) is a frequent cause. With increased international travel, cases of travel-related myiasis have become more prevalent, necessitating awareness among healthcare providers in non-endemic regions.
We present a case of cutaneous myiasis in a 69-year-old male who returned to the United States from Belize. The patient exhibited a painful skin lesion on his right knee, initially suspected to be an insect bite. The diagnosis was confirmed through ultrasound imaging, which revealed the presence of a subcutaneous larva. Conservative larva removal efforts failed, leading to surgical extraction of the larva.
The surgical intervention successfully removed the larva in its entirety, with the wound healing well after the procedure. Pathological examination confirmed the larva as . The patient experienced a satisfactory recovery, with no complications observed during follow-up.
This case underscores the importance of considering myiasis in the differential diagnosis of patients presenting with painful skin lesions following travel to tropical regions. As globalization increases, healthcare providers should be vigilant in recognizing and appropriately treating travel-related diseases such as myiasis to ensure prompt and effective care.
人体蝇蛆病，即双翅目幼虫对组织的侵袭，通常表现为疼痛性、隆起的皮肤病变，在拉丁美洲等热带地区尤为常见，其中人体肤蝇是常见病因。随着国际旅行的增加，与旅行相关的蝇蛆病病例变得更加普遍，这就需要非流行地区的医疗服务提供者提高认识。
我们报告一例69岁男性的皮肤蝇蛆病病例，该患者从伯利兹返回美国。患者右膝出现疼痛性皮肤病变，最初怀疑是昆虫叮咬。通过超声成像确诊，显示皮下有幼虫。保守的幼虫清除方法失败，导致手术取出幼虫。
手术干预成功完整取出幼虫，术后伤口愈合良好。病理检查证实幼虫为人体肤蝇。患者恢复良好，随访期间未观察到并发症。
该病例强调了在对前往热带地区后出现疼痛性皮肤病变的患者进行鉴别诊断时考虑蝇蛆病的重要性。随着全球化的加剧，医疗服务提供者应警惕识别并妥善治疗与旅行相关的疾病，如蝇蛆病，以确保及时有效的治疗。
