Looks like it could very well be aglaonema cecilia, or related variety. There are quite a few varieties of aglaonema, many of which have stripes, spots, moddeled colors...a lot of varieties have vibrant reds and pinks. If it is an agaonema, keep it away from bright direct sunlight, it will wilt and die. These guys like low to medium light levels. A great plant for any room in the house that recieves some light. They like water, but need some good drainage. They are really easy to care for, but can get root rot if they stay to wet.

I agree with Vmates I have one of those mine looks like that when new leaves form or I over water it.
