Mutter Museum unveils skeleton exhibit for Rare Disease Day

PHILADELPHIA (WPVI) -- The Mutter Museum's newest exhibit is dedicated to a long-time Philadelphia resident.

In commemoration of Rare Disease Day, the museum unveiled the skeleton of Carol Orzel.

Orzel died last year after more than 35 years of living with Fibrodysplasia Ossificans Progressiva or FOP.

Orzel was 58.

FOP causes the body's tissues to harden and turn into bone.
