KNH successfully removes 20KG of breast tissue from teen with Gigantomastia

The 11-hour operation was conducted on September 22, 2025, relieving a heavy burden from Lydia Musivi, who had battled the rare and severe condition for more than 18 months. The removed tissue accounted for 37 per cent of her total body weight.

“This was more than a surgical success; it was the restoration of a young woman's dignity and future,” said Dr. Benjamin Wabwire, Head of Specialized Surgery and Consultant Plastic and Reconstructive Surgeon, who led the procedure. 

Lydia’s condition had caused her extreme pain, rapid breast growth, skin infection and profound emotional distress. It left her unable to walk or stand upright without pain, forcing her to abandon her studies. She expressed relief and joy at her new life. 

According to KNH, Lydia expressed relief saying “the weight is now over. I feel free, lighter, and ready to return to school.” 

The teenager hopes to return to school to fulfil her dream of becoming a teacher. 

The landmark procedure brought together a multidisciplinary team of experts, including Professor Lew and Dr. Kim from South Korea's Yonsei University, together with KNH's own Dr. Claire Odero, Dr. Agnes Wanjiru, and Dr. Joy Mwangi. 

Dr. Eileen Towett and Dr. Hellen Mwari led the anaesthesia team, while Esther Munga and Eun Jin Chae provided critical nursing care. 

Lydia’s mother, Naomi Mutendwa, recounted her painful journey of years of searching for help.

“I watched my daughter disappear under the weight of this illness. It stole her confidence and her future. We felt hopeless until we were referred to KNH from Garissa County Referral Hospital,” she told KNH. 

“The team here saw the girl, not just the condition. They didn’t just treat her; they gave me back my daughter. They have given her a second chance at life.”

Acting Chief Executive Officer, Dr. Richard Lesiyampe, termed the breakthrough as the “world- class” highlighting KNH’s role as a beacon of medical excellence in Africa and beyond and the Kenya’s growing capacity for advanced medical innovation. 

“We are solving local health challenges with a global standard of innovation and a deeply human touch, setting new benchmarks for patient-centred care,” said Dr. Lesiyampe,

Lydia has since been discharged from the hospital and is recovering at her home in Mwingi, Kitui County, with plans to rejoin her classmates in January 2026.
