A Chinese grandmother has a five inch horn growing out of her forehead.

The horn curves downward and looks like the stalk of a pumpkin, reports the Yangcheng Evening Post.

Granny Zhao, 95, of Zhanjiang city, Guangdong province, says it first appeared three years ago.

"At first, it was only a mole, but it gradually grew and became like a horn," she said.

Zhao says the horn causes her little trouble except to affect her vision slightly: "It causes me no discomfort, but blocks part of my view."

But her family are hoping that medical experts can explain the phenomenon.
