Missing an entire month of studying in med school would make it very difficult to catch up with all the learning that was supposed to happen in that month, even if the path course spanned the whole year. Missing 1 month of a 2 month course would be even harder. Pathology is a massive, and important, course, and should be studied for appropriately. I missed a week of school several weeks ago and it has been so hard to make up for that week while studying the current stuff.
Of course, if your circumstances absolutely prevent you from studying for an entire month, then there is nothing you can do, and it doesnt really matter if people think path in 1 month can be done or not. But if there is any way to avoid missing a month of studying, do that.
It would be possible to just learn just the Path highest yield facts in 1 month, but it wouldnt be preferable because you would be missing out on some of the foundation and just trying to memorize completely random facts about each disease.
