Hmmm..... Think think think think. Well I really don't remember other scary stories for children but these are all that I can think about.
The Japanese ghost story called "Snow Witch"

There was also an old western horror story that talks about a Black Rider that is like a ghost, or a ghost town which was where the idea of the "Ghost Rider" originated from. I couldn't find any books about it except for info and research about it. Like these links:

There are other popular horror stories like these for example:
"Dr. Jekyll and Mr. Hyde"
"Frankenstein" by Mary Shelley
"The Island of Doctor Moreau"
Well, that's about it.
They might be for children, but if they're not, then I'm sorry. :(
I'm only trying to help.
EDIT:
Goosebumps is also another example as well.
