Stefan Zoleik lived for about a decade with a massive facial growth linked to Madelung disease (multiple symmetric lipomatosis), which can cause large fatty tumors around the neck/upper body and, in rare cases, the face. In 2014, surgeons removed a tumor reported around 13 pounds (6 kg), dramatically changing his ability to function and be seen in public again.
The condition itself isn’t usually cancer, but the growth can become disabling—causing pain, breathing issues, and severe disfigurement. His case went viral because it shows how a “benign” disorder can still destroy someone’s life until surgery becomes the only way forward.
