Nguyen Duy Hai is seen with his mother and his 180-pound tumor at FV Hospital Wednesday in Ho Chi Minh City before surger

*(Via CNN) — A Vietnamese man is recovering in the intensive care unit after surgery that completely removed from his right leg a tumor twice his body weight, according to hospital officials in Ho Chi Minh City.

The growing tumor had rendered the patient, Nguyen Duy Hai, virtually immobile until his surgery.

The excised tumor weighed 180 pounds (82 kilos), according to the hospital, a bit less than the 200 pounds (90 kilos) estimated before surgery.

Hai, 31, of Da Lat City, has Von Recklinghausen’s neurofibromatosis, said Dr. Jean-Marcel Guillon, chief executive officer of FV Hospital, where the 12-hour procedure was performed.

The autosomal dominant hereditary disorder is the same disease that contributed to the extraordinarily large head of Joseph Merrick, whose story was dramatized in the 1980 film, “The Elephant Man,” explained Guillon.

The tumor “may return,” Guillon wrote in an e-mail to CNN, “but we can operate him again, and it won’t never reach such a size anymore.”
