Zhang Ruifang, 101, of Henan province in China, appears to have a horn growing on the left side of her forehead. Another is reportedly sprouting on the right side, according to the Daily Mail. I know, I know, the Daily Mail… but look at that horn. Just look at it. From the Daily Mail:

Although, it is unknown what the protrusion is on Mrs Zhang's head, it resembles a cutaneous horn.

This is a funnel-shaped growth and although most are only a few millimetres in length, some can extend a number of inches from the skin.

Cutaneous horns are 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.

They usually develop in fair-skinned elderly adults who have a history of significant sun exposure but it is extremely unusual to see it form protrusions of this size.

The growths are most common in elderly people, aged between 60 and the mid-70s. They can sometimes be cancerous but more than half of cases are benign.
