Cutaneous dirofilariasis caused by Dirofilaria repens is a parasitic disease in dogs and cats. It is exceedingly rare in man who is an occasional host. The parasite fails to reach maturity. The true incidence of dirofilariasis is probably greater than recognized. This can be explained by the apparent benign nature of the lesions that may not warrant excision.
A 12-year-old girl presented a cutaneous nodular lesion involving the forehead. Surgical excision allowed diagnosis: cutaneous dirofilariasis caused by Dirofilaria repens. The child had always stayed in mainland France. Histopathological examination showed the worm trial with inflammatory granulomatous reaction of the deep dermis. The parasite extraction allowed successful treatment.
This new case of cutaneous dirofilariasis emphasizes that this parasitic disease is present in mainland France. The infection is more common in Southern France. The present report describes a pediatric case in Gironde, where it is exceedingly rare. Microscopic examination identified, and it was unusual, a male worm.
由匐行恶丝虫引起的皮肤恶丝虫病是犬猫的一种寄生虫病。在作为偶然宿主的人类中极为罕见。该寄生虫无法发育成熟。恶丝虫病的实际发病率可能高于已认识到的情况。这可以通过病变明显的良性性质来解释，这种病变可能无需切除。
一名12岁女孩前额出现皮肤结节性病变。手术切除后得以确诊：由匐行恶丝虫引起的皮肤恶丝虫病。该儿童一直居住在法国本土。组织病理学检查显示虫体及真皮深层的炎性肉芽肿反应。取出寄生虫后治疗成功。
这例新的皮肤恶丝虫病病例强调了这种寄生虫病在法国本土存在。该感染在法国南部更为常见。本报告描述了吉伦特省的一例儿科病例，在该地此病极为罕见。显微镜检查鉴定出一条雄虫，这很不寻常。
