Enterobius vermicularis in an ectopic location usually represents an incidental finding in tissue specimens in a patient without symptoms. However, the parasite can lead to inflammation and symptoms in rare cases.
A 36-year-old woman had an abdominal hysterectomy for menorrhagia, dyspareunia, and lower abdominal pain. Two small nodules from the posterior aspect of the left broad ligament as well as the uterus were sent for histologic examination. The pathologic findings confirmed the diagnosis of "granulomatous peritoneal nodules due to E. vermicularis." Within the nodules were aggregates of ova of E. vermicularis.
This case reminds us that such granulomatous lesions can simulate leiomyoma, fibroma, endometrioma, and tuberculous or malignant lesions. It is important to be aware of this resemblance to avoid unnecessary surgical intervention.
蛲虫异位通常是在无症状患者的组织标本中偶然发现的。然而,这种寄生虫在罕见情况下可导致炎症和症状。
一名36岁女性因月经过多、性交困难和下腹部疼痛接受了腹部子宫切除术。从左侧阔韧带后部以及子宫取出的两个小结节送去做组织学检查。病理结果证实为“蛲虫引起的肉芽肿性腹膜结节”。结节内有蛲虫卵聚集体。
该病例提醒我们,此类肉芽肿性病变可类似平滑肌瘤、纤维瘤、子宫内膜瘤以及结核或恶性病变。认识到这种相似性对于避免不必要的手术干预很重要。
