Lizzie Bell -- the 15-year old Tucson girl featured on ABC'S "Extreme Makeover Home Edition" -- remains in the hospital this evening.

     Her family is preparing for the possibility that she could need a bone marrow transplant. 

     Lizzie has Diamond Blackfan Anemia...a rare blood disorder that requires frequent blood transfusions.

     She was admitted to the hospital last weekend -- after coming down with the flu and pneumonia. 

     Now...in addition to her recovery...the search has begun for a perfect bone marrow match. 

     The family will hold a marrow drive next month -- June 14th.
