All that can be said for this solution is that it works on your test string. Beyond that? 

my $str = q["2","T,E,S,T,B","Lazowsky","Mike's","Teststring"];
$str =~ s< \s* ( \"[^\"]+ \" \s* ) (,|$) > 
         < (local $a = $1) =~ tr/,//d;  $a . $2 ; >gex; #!"
print $str;
__END__
#Output
C:\test>229505
"2","TESTB","Lazowsky","Mike's","Teststring"

C:\test>

Update: Corrected error that LAI++ spotted.

That said, Text::CSV is almost certainly better.

Examine what is said, not who speaks.

The 7th Rule of perl club is -- pearl clubs are easily damaged. Use a diamond club instead.
