The diagnosis? Fir on the lung

The annals of medical anomalies bulge with stories from far-flung places where the idea of a reliable source is a chap sitting on a gate in a goatskin fleece who waves to passersby, even if there are none. And so to the Urals, where medics are reported to have removed a tiny fir tree from a man's lung, after he complained of chest pains. Before doctors opened him up, they were convinced he had lung cancer.
Now, they're convinced he inhaled a seed, which sprouted inside him.
