I know that in Tanzania and some other African countries albinos and their albino body parts are regarded as possessing magic powers -- their use can help in magic cures. I had seen stories about mutilations of albinos; the hunting down of albinos and trafficking of albinos across borders.
This bizarre practice has grown large enough to elicit a Rwandan counter-campaign.
