Human dirofilariosis is a zoonosis caused by different Dirofilaria species: D. repens, D. immitis, D. tenuis and D. ursi, thin nematodes belonging to the Onchocercidae family, whose larval stages are generally found in the natural (felines and canids) or accidental (human) definitive host. In Europe, human infection is rare, even in areas considered endemic such as Spain or Italy. In this paper we describe the case of an 82-year-old woman living in Modugno (Bari municipality), who came to our observation for a subcutaneous nodule on her right thigh that had appeared in the previous two weeks and gradually became necrotic. The woman lived in an apartment with a dog. An adult worm, white, thin, about 140 mm long, came out of the necrotic area spontaneously. After microscopic examination, the worm was identified as D. repens. In Apulia, a South-Italy region, human dirofilariosis is a rare disease and since 1885 only 11 cases have been reported. In recent years we have witnessed an increase in the number of diseases transmitted by vectors at all latitudes, and in our region an increase in the Aedes albopticus population has been reported, so it is reasonable to expect an increase in dirofilariosis cases in humans.
匐行恶丝虫、犬恶丝虫、蒂氏恶丝虫和熊恶丝虫，这些细长的线虫属于盘尾丝虫科，其幼虫阶段通常存在于自然终宿主（猫科动物和犬科动物）或偶然终宿主（人类）中。在欧洲，即使在西班牙或意大利等被认为是地方病流行的地区，人类感染也很罕见。在本文中，我们描述了一名居住在莫杜尼奥（巴里市）的82岁女性的病例，她因右大腿出现一个皮下结节前来就诊，该结节在过去两周内出现并逐渐坏死。该女性与一只狗住在一套公寓里。一条白色、细长、约140毫米长的成虫从坏死区域自行钻出。经过显微镜检查，该蠕虫被鉴定为匐行恶丝虫。在意大利南部的普利亚地区，人体丝虫病是一种罕见疾病，自1885年以来仅报告了11例。近年来，我们目睹了所有纬度地区由媒介传播的疾病数量都在增加，并且在我们所在地区，已报告白纹伊蚊数量有所增加，因此预计人体丝虫病病例会增加是合理的。
