Assuming you only want a lower-case 'p', you can try this:
use strict;
use warnings;
while (<DATA>) {
my $wordchars = q|[-'\w]|;
while ( /\b($wordchars*p$wordchars+|$wordchars+p$wordchars*)\b/g ) {
print "$1\n";
}
}
__DATA__
Use Perl.
Perl is appealing.
Use it to write a killer app.
If you want an upper-case 'P' to be included, change the regex to:
/\b($wordchars*[Pp]$wordchars+|$wordchars+[Pp]$wordchars*)\b/
The $wordchars variable is a character class that defines what characters are allowed
in "words".
