After a corruption in an ext4 filesystem, I've checked and moved to the
correct position all the files and dirs in lost+found, but one of the dirs is
corrupted.
The "ls -l" command says:
d????????? ? ? ? ? ? /lost+found/#90116
If I try to remove it with "rmdir" or "rm -rf" or "mv" or "unlink", all
commands say:
<command used>: failed to remove `#90116': Input/output error
Running "fsck" says that the filesystem is OK.
Is there a way to remove that corrupted dir?

You can probably check "lsattr /lost+found/#90116" to see if either the "i" (immutable) or "a" (append-only) attribute is set. If yes, then running "chattr -i -a/lost+found/#90116" will remove those attributes, and it should be removable.

If it was an immutable or apppend-only attribute, it should have
resulted in a "Operation not permitted" error. I suspect the problem
may be an underlying disk error. You might want to check "dmesg", and
see if the hard drive is reporting I/O errors. It may very well be
that you have problems a lot more serious than just a corrupted file
system. If so, you might want to consider making an immediate backup
right away, and strongly consider replacing the hard drive if you find
I/O errors in your system logs.
