Human subcutaneous dirofilariasis is a rare infection caused by filarial worms of the genus Dirofilaria. The parasites are transmitted to man by mosquitoes and the infection is manifested as subcutaneous nodules. Excision of the lesion is both diagnostic and therapeutic. Hereby we report three cases of human subcutaneous dirofilariasis. The worms were sent to our department for identification over a period of four years (2006-2009). Of these three patients, two men and one woman were between 15 and 45 years of age. In two cases, the infection manifested as a nodule on face, in one case near lower eyelid and in the other on the cheek, while in the third case as an itchy nodule on the abdomen. It is emphasized that both clinicians and microbiologists should have an increased awareness of this entity and include dirofilariasis in the differential diagnosis of patients presenting with subcutaneous nodules.
人体皮下丝虫病是一种由恶丝虫属的丝虫引起的罕见感染。这些寄生虫通过蚊子传播给人类，感染表现为皮下结节。病变切除既是诊断方法也是治疗手段。在此我们报告三例人体皮下丝虫病病例。在四年期间（2006 - 2009年），这些虫体被送至我们科室进行鉴定。这三名患者中，两名男性和一名女性，年龄在15至45岁之间。在两例病例中，感染表现为面部结节，一例在下眼睑附近，另一例在脸颊，而第三例表现为腹部的瘙痒性结节。需要强调的是，临床医生和微生物学家都应提高对该疾病的认识，并将丝虫病纳入皮下结节患者的鉴别诊断中。
