Health Condition Makes Boy Grow Tortoise Shell On His Back. Didier Montalvo, from rural Colombia developed congenital melanocytic nevus, which causes moles to grow all over the body at an incredibly fast rate. As a result of this disease, a mole grew so large that it covered Didier’s entire back.
He was dubbed ‘turtle boy’ by his peers as the huge mole looked like a shell.Apparently, Didier was conceived on an eclipse and the locals believed his mole was the work of the devil. For this reason, he was shunned by other children and banned from the local school.
When British surgeon Neil Bulstrode heard about Didier’s condition, he travelled to Bogota so he could operate and remove the mole. Didier was six years old when the surgery was performed. It was a success and the whole mole was excised. After the operation, Didier now goes to school and lives a normal, happy life.
