How to remove blueish ghost in scanned slide

I scanned some old slides from my family. The protective platic
sleeves they were in touched the emulsion side of the slide and caused
a blueish "ghost" or region to appear on some slides. In every slide
it's different. How can I correct this blue odd shapped region in
Photoshop? Thanks for any help.

Look at the channels. Does one channel have more of the "ghost" than
another? If so, try using the channel mixer to eradicate the "ghost"
and then work on the image normally to get the rest of the colour
balance right.
