Nose-like: A 3cm growth formed from nasal tissue, bone and nerve branches was discovered
At the Hospital de Egas Moniz in Lisbon, Portugal, the unnamed woman, a U.S. citizen, had tissue from her nose implanted in her spine.
Doctors hoped the cells would develop into neural cells and help repair the nerve damage to the woman's spine.
But the treatment failed.
However, last year, eight years after the stem cell operation, the woman, then 28, complained of increasing pain in the area.
Doctors discovered a three-centimetre-long growth, which was found to be mainly nasal tissue, as well as bits of bone and nerve branches that had not connected with the spinal nerves.
Neurosurgeon, Brian Dlouhy from the University of Iowa Hospitals and Clinics in Iowa City, who removed the growth, said it was benign, but was secreting a 'thick copious mucus-like material', which was probably why it was painfully on her spine.
Jean Peduzzi-Nelson, a stem cell researcher at Wayne State University in Detroit, Michigan, who advised the team who conducted the surgical technique – which had been tested on rodents – said that most of the recipients of the nasal tissue who received the right kind of rehabilitation after their surgery experienced improvement.
She told the New Scientist: 'I am saddened to learn of this adverse event, however, the incidence of this problem is less than one per cent.
'Many patients receiving this treatment have had remarkable recovery.'
In 2010, the Lisbon researchers published their results using this method on 20 people paralysed at various locations in their spine.
Eleven experienced some recovery of movement or sensation; one person's paralysis got worse, one developed meningitis and four others experienced minor adverse events.
While often championed as the future of medicine, stem cells' ability to metamorphasise and increase carries an inherent danger, namely that when when implanted into a person they could turn into dangerous cancer cells.
CHINESE MAN HAS NOSE GROWN ON HIS FOREHEAD TO REPLACE ORIGINAL WHICH WAS DAMANGED IN A CAR CRASH
In September last year a Chinese man had a new nose, which grown on his forehead, transplanted.
The man, who has only been named as Xiaolian, had the treatment to create a replacement for his original nose which was infected and deformed.
The procedure was carried out at a hospital in Fuzhou, Fujian province.
As a result, an infection corroded the cartilage leaving the surgeons unable to repair it.
They were left with no choice but to grow him a new nose and then to transplant it in place of his damaged one.
The nose was created by placing a skin tissue expander onto Xiaolian’s forehead.
This was cut into the shape of a nose and was supported by cartilage taken from the man’s ribs.
Surgeons say that the nose has developed well and that the transplant surgery will be carried out soon.

The 22-year-old damaged his nose in a traffic accident in August 2012 but failed to seek treatment.As a result, an infection corroded the cartilage leaving the surgeons unable to repair it.
