what are the names of blood diseases that start with the letter P?

im looking for a specific blood disease to do research on but i can not remember what it is or how to spell it exactly.I know i will be able to recognize it when i saw it.i tried to find a list from the web but apparently that is harder to find than i ever imagined.im hoping someone out there will be able to give me such a list so i can move forward with my investigation.:)
