A Tree Grows In...

I opened up the patient's chest,
Expecting cancer in his lung.
Instead, I never could have guessed.
In the tissue a tree had sprung;
A pine tree to be more exact.
I guess the guy inhaled a seed
That lodged just so inside the tract,
And sprouted right there, yes indeed!
The patient was in pain, no doubt,
And was fearing the very worst.
I excised all the tree parts out.
The operation was a first.

The patient should recover fine.
Of course, I could not save the pine.
