After 25 years of lying in a woman's stomach, a felt-tip pen was still in working order. How did it get into her stomach? When the 76-year-old woman went to a doctor due to weight loss and diarrhea, an investigation with a scope and a computed tomography (CT) scan revealed the item. "She recalled unintentionally swallowing a pen 25 years earlier. While she was interrogating a spot on her tonsil with the pen she slipped, fell and swallowed the pen by mistake," the doctors wrote in 2011 in the journal BMJ Case Reports. "Her husband and general practitioner dismissed her story, and plain abdominal films done at the time were reported as normal." Though her symptoms resolved on their own and there was no stomach damage, the doctors decided to remove the felt-tip pen because of the possibility of future damage to her stomach.
