Pdf opened in Acrobat different in Illustrator

10-11  Source: Network gathering  Views:1 

I received a pdf that opens in Acrobat and Photoshop one way, (as a 3.5x2 business card) then opens as an 8.5 x 11, 10 up set of bus cards in Illustrator. How is this happening? (I do get font substitute message, but what would that have to do with seeing entirely different content?)  I want to open the file as it opens in Acrobat but that version/page is no where to be found when opened in the other applications.
Sounds like the pdf was cropped within Acrobat. Acrobat has a strange way of cropping. I'll bet that if you open the pdf in Acrobat (Standard or Pro...?) and select Crop Pages, you will see the same extraneous content in the preview. In short, Acrobat modifies (modified in this case) a documents crop data, but does not delete the image data.
(I don't often call things a bug, I consider this to be one)
