Gottfried Benn was a poet and a doctor. He seems to have combined those interests in some very odd ways. I just downloaded his poems from this site and they are grotesque in the best sense. Try this poem:

Little Aster

A drowned beer hauler was heaved onto the slab.
Someone had heaved a lavender aster
between his teeth.
As I reached through the chest
under the skin
with a long knife
to cut out the tongue and palate
I must have bumped the flower, for it slid
into the brain lying alongside.
I packed it into the chest cavity
with the sawdust
as we sewed up.
Drink your fill in that vase!
Rest in peace,
little aster!

That comes from a collection called "Morgue," which you can dowload as a pdf at the link. Enjoy.
