Terminal ileum schistosomiasis with perianal fistula mimicking Crohn's disease.

Schistosomiasis is a parasitic disease related to water contact in the agricultural fields, affecting millions of people in developing countries in tropical and subtropical parts of Africa, Asia, and South America. We report a case of a 27-year-old male, with intestinal schistosomiasis associated with perianal fistula mimicking Crohn's disease, where the terminal ileum showed a cobblestone appearance, and histopathological biopsy showed schistosoma granuloma.
