Stool specimens of 1238 workers in western region of Saudi Arabia were examined for infection with intestinal parasites and for fecal occult blood (FOB) to investigate the possibility that enteroparasites correlate to occult intestinal bleeding. Direct smears and formal ether techniques were used for detection of diagnostic stages of intestinal parasites. A commercially available guaiac test was used to detect fecal occult blood. 47.01% of the workers were infected with intestinal parasites including eight helminthes species and eight protozoan species. The results provided no significant evidence (P-value = 0.143) that intestinal parasitic infection is in association with positive guaiac FOB test.

“…A 76-year-old male patient underwent a transverse colectomy for a presumed adenocarcinoma. The mass was non-obstructing and on histological examination had E. vermicularis eggs in the submucosa layer 16. Similarly, in a patient with an apparent sigmoid mass, E. vermicularis was found on histological examination of the resected specimen 17…”

Large-bowel obstruction secondary to Enterobius vermicularis pseudotumour

Enterobius vermicularis infection is typically observed in paediatric patients and manifests with perianal pruritus, but other manifestations or ectopic presentations have been reported in the literature. We present the case of a man in his 60ss with a large-bowel obstruction with symptoms including a 4-day history of progressive abdominal pain, distension, vomiting and absolute constipation. On examination, his abdomen was distended with tinkling bowel sounds on auscultation. Cross-sectional imaging demonstrated an obstructing mass in the distal descending colon. An emergency laparoscopic Hartmann’s procedure was performed and the patient made an uneventful recovery. An intraoperative colonoscopy demonstrated numerous white threadworms in the colon. Histological analysis demonstrated a pseudotumour related to Enterobius vermicularis infection. This case represents a rare differential diagnosis for a large-bowel obstruction.

“…The pathologic findings in our case were similiar with those of previous reports. Chronic inflammatory intestinal obstruction due to E. vermicularis [12] and infestation of this parasite presenting with transverse colon carcinoma have been described [13]. Therefore, it would have been impossible to differentiate malignancy from parasite infestation in our patient without histological examination.…”

“…Inflammatory pseudotumors due to parasites have also been described in the liver [8], eye [9], ileum, and colon [10][11][12]. E. vermicularis infection of the transverse colon presenting with colon carcinoma has also been reported [13]. As far as we know, this is the first case report of an inflammatory pseudotumor of the sigmoid colon due to E. vermicularis.…”

“…With respect to parasites, inflammatory pseudotumors have been described to be due to bilharziasis in liver [8], dirofilariasis in the orbit [9], and ascaris in the heart [20] or in the abdomen [21]. E. vermicularis infection in transverse colon with colon carcinoma has also been reported [13]. Inflammatory pseudotumors have been described to originate from various organs and manifest with a wide spectrum of clinical symptoms, depending on the site of origin.…”

For the first time, we report a case of an inflammatory pseudotumor of the sigmoid colon originating from an infection withEnterobius vermicularis. A 42-year-old man presented with left lower abdominal pain, weight loss, fever, nausea, and vomiting. Physical examination revealed tenderness and a palpable mass in the left lower quadrant. Laboratory results demonstrated elevated leukocyte count. Colonoscopy showed 25 cm above from the anus a nonobstructive, approximately 4 × 4 cm irregular lesion narrowing the sigmoid colon lumen with erythematous and rough mucosa; a diverticulosis could not be observed. Colonoscopic biopsy showed inflammatory changes. Computerized tomography (of the abdomen showed a 10 × 6 × 6 cm mass at the left lower abdomen. On abdominal exploration, the mass in the sigmoid colon was detected, and anterior resection of the sigmoid colon was performed. Histopathologic examination of the specimen revealed eggs of the E. vermicularis embedded in the granulation tissue and in the submucosa/mucosa of the sigmoid colon. The patient was uneventful in the postoperative period and discharged 7 days after surgery.
