Pseudomembranous colitis
Colonic biopsy taken from a patient with diarrhea following broad spectrum antibiotic therapy shows
volcanic-like eruption with superficial pseudomembrane formation adjacent to an area of mucosal necrosis.
This disease is caused by Clostridium difficile when the natural colonic flora has been depleted by antibiotics.
