Has anyone seen this before?

I had students doing the basic cheek-cell-under-the-microscope exercise this morning, and one student had a nucleus that was TWO nuclei - two separate stained chambers, one about 2/3 normal nucleus size, the other about 1/3. It was a surface epithelial cell, which are not supposed to divide, and this didn't look like a mitotic pair anyway. It looked like a nuclear deformity, but it wasn't one I'd ever heard of before, and I'd never seen a cheek cell look like this.

I'm curious if anyone else had seen something like this. Of all of the things I've read about abnormal cell changes, this isn't one of them.
