My understanding is that the difference between a Spring Roll and an Egg Roll is that either one can have any filling, but a "true" egg roll will have egg as part of the ingredients.....usually scrambled egg.

Many Asian cultures have different forms of wrappers and things that they make with them. One common would be Lumpia (Fillipino). If it is Shanghai (sp?) style, then they are usually not fried. I've also seen some of the new trendy places do things like wrap a shrimp in the wrapper with the tail sticking out, calling it wrapped shrimp.
