The Russian surgeon who says he found a fir tree growing inside a patient’s lungs is standing by a claim that has been met with wide disbelief in the medical world.
The surgeon, Vladimir Kamashev, said he was "shocked" to find a five centimetre branch while operating on a patient in the central city of Izhevsk. He said he initially thought the branch was a tumour, and suggested the patient could have inhaled a seed during his military service in Siberia that then sprouted.
But Dr Stephen Spiro, vice chairman of the British Lung Foundation, said that would be "pretty near impossible."
Graeme Berlyn, a professor of tree anatomy at Yale University, said a fir seed could not germinate in the lung because it needs sunlight.

All sources on this are making the same claim - that the man must've inhaled a seed or bud, and the 5-cm long fir tree then grew inside of his lung.
This is a photo of the tree once it was extracted from the lung:
There doesn't seem to be any roots there. Snopes doesn't have an article on this.
Did this 5-cm long 'tree' really grow inside this man's lung?
