“…In contrast, different types of papillary, mucinous and tubular adenocarcinoma were observed in colonic carcinoma patients. Cheever and Andrade (1967) and Chassot et al (1998) showed that schistosomiasis-related intestinal polyps are frequently seen in Egyptian cases of intestinal schistosomiasis, which is different compared to most other endemic areas. Colonic involvement has been demonstrated to be meagre in Brazilian cases, rarely exhibiting polyps, and with no signs of a particular relationship with colonic cancer.…”

“…The preferred site for S. mansoni and S. haematobium is the digestive tract and urogenital tract, respectively. Ectopic forms of schistosomiasis, most of which are secondary to S. mansoni and Schistosoma japonicum, are found in the digestive, urogenital, central nervous, cardiovascular, pulmonary, dermatological, and ophthalmological systems [3][4][5][6].…”

Background Ocular damage, including damage to the conjunctiva, lacrimal gland, eyelids, and orbit, caused by Schistosoma haematobium is sporadic. We report a clinical case of orbital migration of schistosome eggs. Case presentation A 14-year-old boy of Malian nationality presented with a painless swelling of the upper right eyelid, which had been gradually increasing for approximately 3 months. Visual acuity was logMAR 0.10 and 0.00 in the right and left eye, respectively. External examination revealed a right palpebral mass, pushing the globe slightly downward and inward. Computed tomography revealed a mass of the right lacrimal gland. Total excision of the mass was performed by transpalpebral orbitotomy. Pathological examination revealed an inflammatory granulomatous infiltrate of the lacrimal gland consisting of lymphocytes, eosinophils, giant cells, epithelioid cell, histiocytes and calcified Schistosoma eggs with terminal spine. Urine examination revealed eggs of S. haematobium. Praziquantel 40 mg/kg was administered to the patient. The hematuria stopped after 1 week. After 3 years of follow-up, no recurrence was noted. Conclusions The bilharzian granuloma of the lacrimal gland is an ectopic site of the parasite. In this case, the granuloma was cured by surgical excision followed by a course of Praziquantel.

“…Intestinal schistosomiasis is usually caused by S. mansoni, S. japonicum, S. mekongi, or S. guineensis and rarely by S. haematobium (4). Intestinal polyposis in cases of schistosomiasis has previously been reported and is usually due to S. mansoni and rarely due to S. japonicum or S. haematobium (1,2,4).…”

The Brief Case: Benign Rectal Polyp with Schistosoma mansoni

We report a case of a 40-year-old female of Yemeni background who presented with abdominal pain. The pain started 14 months prior and was localized to the epigastrium, was precipitated by eating, and was of a burning and itching type. The pain occurred every 2 to 3 days, lasted for several minutes, and was associated with intermittent nausea. She occasionally had dysphagia with solid foods, but this did not interfere with her daily activities. There was no history of constipation, diarrhea, vomiting, or blood in the stool. There was no history of recent travel, and she had not been clinically evaluated since her last visit to Yemen. Her family history was significant for gastric and colon cancers. Physical examination was negative for abdominal or rebound tenderness. Although her complete blood counts were within normal reference ranges, she did have a history of microscopic hematuria. No stool or urine microscopic examination was performed. The differential diagnosis at that time included gastroesophageal reflux disease, peptic ulcer disease, gastritis, and cholelithiasis. Ultrasound of the abdomen was unremarkable, and the patient was started on a trial of proton pump inhibitors for 1 month. She was also followed up by upper gastrointestinal endoscopy, as well as a screening colonoscopy because of the family history of colon cancer. Endoscopy showed a patchy area of mild nonerosive gastritis involving the antrum and the body of the stomach. On histology, the gastric biopsy specimen showed chronic active gastritis and was positive for Helicobacter pylori by immunohistochemistry. From the rectum, we obtained a single biopsy specimen of a 1-cm, nonbleeding, semipedunculated polyp, which was completely removed by snare cautery. The histologic sections showed benign polypoid colonic mucosa with submucosal granulomatous inflammation, giant cells, and abundant eosinophils. At the center of many of the granulomas were eggs in various orientations, measuring roughly 130 by 60 m (Fig. 1). The shells of the eggs were positive for Ziehl-Neelsen acid-fast stain, and in one section, a large lateral spine was visible (Fig. 2). The features of the tissue reaction, the morphology of the eggs, and the positive Ziehl-Neelsen acid-fast staining were consistent with Schistosoma mansoni. No serological correlation was performed. The patient received praziquantel three times daily for 2 days for schistosomiasis and amoxicillin, clarithromycin, and proton pump inhibitors for 14 days for H. pyloriassociated gastritis. DISCUSSIONBlood flukes (trematodes in the family Schistosomatidae) are a major cause of morbidity and mortality worldwide. Although uncommon in the United States, schistosomiasis (bilharziasis or snail fever) is one of the top three tropical diseases in the world (following malaria and intestinal helminthiasis), more commonly seen in the developing countries of Africa, Asia, and the Middle East (1). According to the World Health Organization, more than 61.6 million people were reported to have been treated for schistosom...
