Ma Zhong Nan, a 93-year-old man living in a small village in China, recounts how a horn began to sprout on his head five years ago. Ma was combing his hair one day and carelessly injured his scalp. Because it was just a small wound, he did not pay much attention to it. Little did he expect that a thick, hard substance started to grow on his head.
Since it did not bother him, he just ignored the growth. But the growth just kept getting bigger and harder, forming a horn of about 10cm (4 inches) long half a year later. Two weeks ago, Ma suddenly felt itching of the horn and his children brought him to see a doctor at the local hospital. But the doctor has no explanation for it. His children are now trying to seek help through the media.
