title: Intraperitoneal Enterobius vermicularis infection: a case report.
abstract: BACKGROUND
  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.
  
  
  METHODS
  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.
  
  
  CONCLUSIONS
  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.
