Zhang Ruifang, a 100-year old

Zhang Ruifang, a 100-year old woman, from China’s Henan Province, has a strange horn coming out of the left side of her forehead. Her bizarre horn started growing last year, and now measures between 5-6 cm in length. It’s reported that the protusion resembles a cutaneous horn, which is made up of compacted keratin, which is the same protein we have in our hair and nails, and forms horns, wool and feathers in animals.
