Cutaneous larva migrans (CLM) is a parasitosis frequently seen in persons who have travelled to tropical or subtropical regions and in those who have worked in contact with soil. The disease frequently develops due to Ancylostoma braziliensis and Ancylostoma caninum species. After penetrating the skin and entering the body, the hookworm larva proceeds to bore tunnels through the epidermis, creating pruritic, erythematous, serpiginous lesions. Secondary bacterial infections of the lesions can often be seen, especially on the legs and buttocks. In this article we presented three atypical local cases which have not been declared previously in our country. The first case, a 54-year-old male who was admitted to hospital in August with complaints of an obverse body rash and itching lasting for a week. Eruptions were observed over a small area on the right side of the abdomen, consisting of itchy, raised, erythematous, curvilinear string-like lesions. Moreover, no eosinophilia was detected in the patient, whose culture showed a growth of Streptococcus pyogenes. The patient was clinically diagnosed with CLM accompanied by secondary bacterial infection and treated for three days with 1 g of amoxicillin-clavulanic acid, mupirocin cream and albendazole 400 mg/d. Under this regime, the lesions were seen to decline. The second case, a 38-year-old male was also admitted in August, complaining of itching and redness on his body. The patient, whose blood count values were normal, exhibited itchy, raised, serpiginous string-like lesions located on the left side of his body. The patient, whose bacterial culture was negative, was clinically diagnosed as CLM and treated for three days with albendazole 400 mg/d and the lesions were seen to improve. The third case, a 23-year old male was admitted in September complaining of itching and redness on his neck. An itchy, crescent-shaped erythematous lesion was detected on his neck; bacteriological cultures and blood count were normal. The common feature for all three cases was the story of working in a hazelnut orchard and mowing weeds using a motorized string trimmer (weed whacker). None of them had a history of travel outside the country. Therefore CLM assumed to be occurred due to the aeration of surface earth layer with the force of motorized string trimmer and entrance of the larvae were from the open parts of the body. In conclusion, it should be keep in mind that hookworm larva-related CLM can be encountered in our country, and reporting of the patients with similar findings are necessary to determine the prevalence of this parasitosis in our country.
皮肤幼虫移行症(CLM)是一种常见于前往热带或亚热带地区旅行的人以及从事与土壤接触工作的人的寄生虫病。该病常由巴西钩口线虫和犬钩口线虫引起。钩虫幼虫穿透皮肤进入人体后,会在表皮内钻隧道,形成瘙痒、红斑、匐行性病变。病变部位常可见继发性细菌感染,尤其是在腿部和臀部。在本文中,我们介绍了我国此前未报告过的三例非典型本地病例。第一例,一名54岁男性,8月因全身皮疹和瘙痒一周入院。在腹部右侧小面积区域观察到皮疹,由瘙痒、凸起、红斑、曲线状条索样病变组成。此外,患者未检测到嗜酸性粒细胞增多,其培养显示有化脓性链球菌生长。该患者临床诊断为CLM伴继发性细菌感染,用1克阿莫西林 - 克拉维酸、莫匹罗星乳膏和400毫克/天阿苯达唑治疗三天。在此治疗方案下,病变逐渐消退。第二例,一名38岁男性也于8月入院,主诉身体瘙痒和发红。该患者血细胞计数正常,身体左侧有瘙痒、凸起、匐行性条索样病变。该患者细菌培养阴性,临床诊断为CLM,用400毫克/天阿苯达唑治疗三天,病变有所改善。第三例,一名23岁男性9月因颈部瘙痒和发红入院。在其颈部检测到一个瘙痒的新月形红斑病变;细菌培养和血细胞计数均正常。所有三例的共同特征是都有在榛子园工作并使用机动割草机(割灌机)割草的经历。他们均无出国旅行史。因此,推测CLM是由于机动割草机的力量使表层土壤通气,幼虫从身体暴露部位进入所致。总之,应牢记我国可能会遇到与钩虫幼虫相关的CLM,报告有类似症状的患者对于确定我国这种寄生虫病的患病率很有必要。
