A 10-year review of the surgical pathology files of the Department of Pathology at Naples Community Hospital (Naples, FL, U.S.A.) revealed 10 cases of Dirofilaria tenuis and one of Dirofilaria ursi infection. The review consisted of only those lesions for which the pathologists had recorded the presence of a worm in the lesion. Therefore, an unknown number of subcutaneous lesions without parasites were not reviewed. Nine of the 11 cases of Dirofilaria were diagnosed as Dirofilaria or Dirofilaria tenuis originally. An additional case, previously diagnosed as Dirofilaria, was found to be a sparganum larva on review. This finding indicates that, because of the unfamiliarity of pathologists with the diagnostic characteristics of these nematode parasites, infections with Dirofilaria are underdiagnosed or misdiagnosed. If pathologists were more familiar with these parasites, their prevalence and the medical cost of this zoonosis in the southeastern United States could be determined more accurately.
对美国佛罗里达州那不勒斯社区医院病理科手术病理档案进行的为期10年的回顾显示，有10例犬恶丝虫感染和1例熊恶丝虫感染。该回顾仅包括病理学家记录病变中存在蠕虫的那些病变。因此，数量不明的无寄生虫皮下病变未被纳入回顾。11例恶丝虫病例中，最初有9例被诊断为恶丝虫或犬恶丝虫。另外1例先前诊断为恶丝虫的病例，经复查发现是裂头蚴幼虫。这一发现表明，由于病理学家对这些线虫寄生虫的诊断特征不熟悉，恶丝虫感染存在诊断不足或误诊的情况。如果病理学家对这些寄生虫更熟悉，就可以更准确地确定它们在美国东南部的流行情况以及这种人畜共患病的医疗成本。
