Kenyatta National Hospital (KNH), Kenya’s premier referral facility, has once again cemented its status as a world-class medical institution by executing a groundbreaking surgical procedure that has set an unprecedented global benchmark. In a display of exceptional surgical expertise, a multidisciplinary team successfully removed a staggering 20.86 kg of hyperplastic breast tissue from a 17-year-old patient suffering from severe gigantomastia.
The Patient and the Pathology: A Battle Against Gigantomastia

The patient, identified as Lydia Musivi, had been afflicted with gigantomastia (also known as macromastia), a rare and often debilitating condition characterized by the excessive, rapid, and often disproportionate enlargement of one or both breasts due to an abnormal increase in mammary tissue.
Impact of the Condition
Prior to the complex, 11-hour surgery, Lydia’s breasts weighed an estimated 37% of her total body weight. This immense mass led to a cascade of severe physical and psychological ailments:
- Physical Debilitation: The sheer weight caused chronic, intractable pain in her neck, shoulders, and upper back. It also resulted in postural deformities, skin ulceration and infections in the inframammary folds, and significant mobility issues.
- Respiratory and Cardiovascular Strain: The size of the tissue could potentially have imposed mechanical pressure, leading to restrictive breathing patterns and increased cardiovascular load.
- Psychosocial Distress: For 18 months, the condition severely hampered her quality of life, leading to social isolation and an inevitable disruption of her education and development.

The Surgical Team and Duration
The complex operation, which lasted an arduous 11 hours, was spearheaded by Dr. Benjamin Wabwire, a distinguished surgeon at KNH. The local team received crucial support and collaboration from international specialist surgeons, ensuring the employment of the most advanced techniques and protocols for such a rare and high-risk case. This collaboration underscores KNH’s commitment to adopting global best practices.
Surgical Significance
The successful removal of 20.86 kg of tissue in a single operation on a pediatric patient represents a world-first in documented medical literature for gigantomastia reduction mammoplasty.
Recovery and Future Outlook
Lydia Musivi is reported to be recovering remarkably well. The immediate relief from the physical burden is palpable, and she is now poised to regain her physical freedom and self-esteem. A critical part of the success story is the restoration of her future: she is set to return to school, a significant milestone that signifies the life-transforming power of the intervention.
This unprecedented surgical victory at KNH serves as a beacon of hope and inspiration for individuals across Africa and the world who face rare and challenging medical conditions. It undeniably positions Kenya’s healthcare sector at the forefront of specialized, complex surgical care.
