Primetime Live: Medical Mysteries: Hypertrichosis/Prophyria/Stomach Cancer

A real-life "wolfman": a man who suffers from a condition called hypertrichosis where an excessive amount of hair grows on the face and body. A girl who suffers from a genetic condition called Porphyria where she burns badly in UV light. A family where eleven members have had their stomachs removed because they carry a gene for stomach cancer that has claimed the lives of family members for the past two generations. Finally, the "you be the doctor" segment with a woman who is thirsty all the time and had hallucinations and muscle spasms.
