I was disassembling a pen kit and looks like a glare or air bubble appeared. Can someone provide information on how to remove this defect?

Is it under the finish? Or is the finish rubbed away from disassembling? If it's rubbed away, and the pen is fully disassembled you can remount it on the lathe and maybe just lightly sand back and reapply your finish?
 
That looks exactly like what John described. Refinishing is likely your only option. I used to have this happen quite often, except not quite as severe. I attributed it to breaking the seal on the ends of the finish when I lightly sand off any CA ridge on the ends after finishing. My solution was to fold up a piece of paper towel, put a few drops of CA on it, and press the ends of the turned tube into it lightly to coat the end grain and restore the seal between the outside finish and the end of the tube after I had sanded it. I don't know your process, but that's what made a difference for me in my regimen. - Dave

PS It looks like a pretty blank. I hope you are able to get it fixed.
 
I agree with John and Dave, looks like the finish has lifted from the wood.

What kind of wood is it? If you don't already, you should add cleaning the turned/sanded blank thoroughly with Denatured Alcohol or Acetone prior to your CA application regimen. This helps remove any oils from the wood or your hands from handling and will help the CA form a better bond.
 
This happens more frequently with oily woods and also if there is a thick build up of CA on the blank and bushing - when separating the bushing from the blank, the CA can raise up. In your case, unintended lateral pressure probably did it, or gripping it with some kind of pliers with a good protective covering between the pliers and blank. With that big of an area, it looks like pliers with the covering deformed it just a smidgen - and that is all it takes.

As mentioned above, it is best to remove the CA, and in my experiences remove ALL of the CA from one end to the other. I turn mine off with tiny bites with a scraper but a skew will also work. It may not seem to be necessary to remove all, BUT if CA is left on in portions that did not lift up, there will be a faint color difference between where CA was NOT removed and where it is removed - and you will probably see that after you re-finish it.
 
Thanks for all the kind suggestions. I am going to put back on the lathe and remove all the ca build up and reapply the ca. Wish me luck.
