Case description

Trichuris Trichuris (whip worm) at the cecum. Colonoscopy revealed a whitish threadlike worm undulating or coiled in the cecum. The adult worm usually reaches 3-5 cm in length and has a lifespan of 1-3 years. Humans are the only known host of T trichiura. The organism is spread via the fecal-oral route. Potential hosts ingest the embryonated (mature) eggs. The eggs hatch in the small intestine, and the larvae attach to and penetrate the small intestinal mucosa, where they begin to mature. After approximately 1 week, the immature worms move passively to the large intestine and proximal colon. The worms' anterior portions penetrate the mucosal epithelium, and the worms can imbed over one half of their length into the mucosal surface.
