Twin found in toddler
Lima - Doctors in Peru have found a "parasitic twin" in the stomach of a three-year-old boy, and plan to surgically remove the tissue on Monday.
Dr Carlos Astocondor of the medical team at Las Mercedes Hospital in the northern port of Chiclayo says the condition occurs in about one of every 500 000 live births.
He says the partially formed foetus weighs 700 grams and is 25cm long.
Astocondor says the brain, heart, lungs and intestines never developed after the foetus was absorbed by the other foetus inside the mother's womb. He says it has some hair on the cranium, eyes and some bones.
