Dirofilariasis due to Dirofilaria repens is a parasitic disease affecting domestic animals and transmitted to man by mosquito bites. Human infestation is rare and involves benign subcutaneous and ocular manifestations. The diagnosis is made by excisional biopsy, which is also the sole recommended treatment. There are few reports of human infection in Tunisia.
We report herein the second case of conjunctival dirofilariasis in a 21-year-old woman residing in Tunis (Tunisia). The clinical presentation evoked orbital cellulites. Clinical and radiological investigations did not provide a diagnosis. Surgical excision and histological examination established the diagnosis by the presence of an adult female worm identified as Dirofilaria repens. Parasite extraction allowed successful treatment.
Dirofilariasis is rare in Tunisia, with only seven cases reported. 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.
由匐行恶丝虫引起的恶丝虫病是一种影响家畜的寄生虫病，通过蚊虫叮咬传播给人类。人类感染较为罕见，主要表现为良性的皮下和眼部症状。诊断通过切除活检进行，这也是唯一推荐的治疗方法。突尼斯关于人类感染的报道很少。
我们在此报告居住在突尼斯突尼斯市的一名21岁女性患结膜恶丝虫病的第二例病例。临床表现疑似眼眶蜂窝织炎。临床和放射学检查未能确诊。手术切除和组织学检查通过发现一条被鉴定为匐行恶丝虫的成年雌虫确诊。取出寄生虫后治疗成功。
恶丝虫病在突尼斯很罕见，仅报告了7例。恶丝虫病的实际发病率可能高于已知情况。这可以通过病变明显的良性性质来解释，这种性质可能不需要切除。
