Doctors at UC San Francisco Medical Center see a lot of things, but even they were stunned by this.

They were treating a 36-year-old man with end-stage heart failure when he began coughing so violently, that he coughed up a 6-inch-wide blood clot from his lungs in the near-perfect shape of his right bronchial tree.

The bright mass that looks like coral is a blood clot.

The doctors were shocked, calling what happened extremely rare.

Despite doctors' best efforts, the man passed away a few days later.
