In Port-au-Prince, Haiti, a small bump on Marlie Casseus’s nose, first noticed in childhood, did not stay small. By her early teens the growth had become a dense, bone-like mass of about seven kilograms — roughly 16 pounds — that engulfed her face. It covered her eyes and mouth, flattened her features, and left only narrow openings for air and liquid food. Neighbors shunned her. Doctors in Haiti offered no treatment. Suffocation and blindness were no longer distant risks; they were imminent.

Marlie had polyostotic fibrous dysplasia, a rare non-hereditary genetic condition in which normal bone is replaced by fibrous tissue that swells and deforms. In its most extreme craniofacial form — historically described as leontiasis ossea, or “lion face” — the skull and jaws can expand until they threaten the airway, orbits and oral cavity. Almost every bone in her body was affected. Her mind was not.

In September 2005 a Haitian charity, Good Samaritan for a Better Life, and Miami’s International Kids Fund arranged a medical visa. She arrived at Holtz Children’s Hospital at the University of Miami / Jackson Memorial Medical Center in critical condition. Surgeons first secured her airway with a tracheostomy. Then, in mid-December 2005, a multidisciplinary team led by maxillofacial surgeon Dr. Jesús Gómez began a marathon operation that lasted 14 to 17 hours. They removed the mass from both sides of her face — more than originally planned — using high-speed saws, then began reconstructing the maxilla, mandible and orbital floors with titanium plates and later bone grafts.

That first procedure was only the start. Over the following years Marlie underwent roughly ten operations at Jackson: recentering the eyes, rebuilding the nose and jaw, replacing implants, clearing infections and scar tissue, and eventually removing the tracheostomy tube. She relearned how to swallow solids and how to speak. When she returned to Haiti in late 2006 she could smile, sip from a cup and dance. Later visits to Miami treated recurrences as the disease continued to remodel bone until skeletal maturity.

The surgeries did not erase every mark of the condition. Fibrous dysplasia can involve the whole skeleton; Marlie remained short, with bowed legs and distorted hands. The facial mass slowly returned in places. She needed further care after Haiti’s earthquakes and storms. Yet she lived far beyond the prognosis she had been given as a child. In 2023 she married her longtime friend Billy Wyatt in Miramar, Florida. She died on 11 March 2024 at the age of 31.

Her case remains one of the most widely reported examples of extreme craniofacial fibrous dysplasia treated by a charity-funded cranio-maxillofacial team. It also remains a reminder of how quickly a treatable deformity becomes lethal when specialized surgery is out of reach.
