Description:This image depicts a condition known as rectal prolapse in a female child due to a parasitic Trichuris trichiura infestation. The rectum has lost its intestinal support due to this nematode invasion, and has emerged from the anal opening. Note the numbers of worms atop the rectal mucosal lining. See PHIL 414, for a close view of a female T. trichiura worm.
The nematode, or roundworm, is also called the human whipworm. The clinical features are most frequently asymptomatic. Heavy infections, especially in small children, can cause gastrointestinal problems (abdominal pain, diarrhea, rectal prolapse) and possibly growth retardation.
