Girl born with missing skin treated with own lab-grown skin

Sumayyah, who was otherwise healthy, was whisked off immediately to the neonatal intensive care unit (NICU), where she was cared for like a major-burns patient.

When she was first taken from the operating theatre to NICU, the doctors were not prepared for her condition because the ACC was not diagnosed before her birth, “as it is not easy through ultrasound”, Ngeow said.

“Both burn patients and Sumayyah have lost the function of their normal skin, so the management is similar – giving antibiotics to prevent infection, and judicious and careful fluid management because they can lose fluid a lot more quickly than if they have normal protective skin over the body,” the neonatologist said, adding that Sumayyah was put in an incubator for extra protection.

A multidisciplinary team, including a neonatologist, a dermatologist and a plastic surgeon, was convened for the baby’s care.

Ngeow ploughed through 800 medical journals about the condition, but the majority, he said, were case reports that “did not give the full picture”, so the team had to piece together what the journals were saying about the rare condition.

The priority was creating skin to cover Sumayyah’s head to prevent infection and even a brain hernia. One option was a split-skin graft, which is normally applied to treat burn patients.

It is where doctors take the top layer of skin from an unaffected part of the body to cover the burnt areas.

“In Sumayyah’s case, it was not an option as she barely had enough skin to cover herself,” Ngeow said.

SGH cultures and grows skin

Plastic surgeon Cheryl Hui, also from SGH, said the hospital, being the only specialised facility managing major burn injuries in South-east Asia, has the capability to culture and grow skin.

“We took a small part of the skin from Sumayyah’s groin (on day 10 after her birth) and put it in the laboratory for three weeks to grow, and we managed to expand it into a few sheets. But because it takes three weeks to grow the cells, we had to make sure she did not have any chance to develop an infection (in the meantime),” she said.

On day three, the team used an artificial dermal matrix, a specialised “scaffold” used in surgery to replace or repair the deep layer of skin, and laid it over the baby’s scalp to protect her brain.

On day 10, more of the artificial skin, which was working well on the scalp, was attached to her torso and limbs. That was the same day doctors took a skin sample from her groin to grow new skin.

Ngeow said: “We changed her dressing every two to three days throughout the whole process (for 29 days). When the actual skin came a month later, we used that to do the graft over the child and continued to change her dressing every two to three days for six months. We even bathed the baby in a sterile saline bath.”

He added that how they bathed the baby was improvised from what he learnt in the field during his national service.

“We set up a drip stand and the (saline) bag was set up to provide a clean source of water for the baby. We also placed her under a warmer to ensure she did not lose heat. We did this every two to three days until the skin grew, and she had beautiful coverage,” Ngeow said.

Sumayyah was discharged after six months, and the team continued to change her dressing – sometimes at the hospital and other times at her home.

Like burn patients, Sumayyah has to deal with scars and often goes for what the doctors call scar revision operations at KK Women’s and Children’s Hospital. Her grafted skin is considered scar tissue, which does not grow and stretch like normal skin.

Her doctors say she will need regular follow-up and scar management through her growing years, and with consistent care, they expect her to lead a full, normal life.

While the skin graft provides a protective covering for her brain, it does not have the structures needed to grow hair, so Sumayyah is bald.

To spare her from feeling different, her father shaves his head.

“But she tells me not to, as she says she will be fine,” he said.

An intelligent child who is chatty when she is at home, Sumayyah has since become rather quiet and withdrawn as she is beginning to be rather self-conscious about her condition, her mother said.

Ngeow said: “As she grows up, she may have to navigate the reactions of other children and strangers who notice that her appearance is different. Hence, supporting her confidence and social adjustment will be just as much a part of her care as looking after her skin.”

Sumayyah will start primary school in 2027, and Ngeow has written a letter to both the Ministry of Education and her school asking that she be allowed to wear a beanie to school.

Siti said: “We felt lost and shocked (when Sumayyah was born), but the doctors, nurses and even the cleaners in the NICU assured and comforted us. They told us to think positive and trust that they will do their best. Our trips up and down, from (home to) hospital, were always teary, but the staff kept us calm and talked us through our worries.

“We are still touched because they took care of Sumayyah like their own. We are deeply grateful and thankful to each and every one of them.”
