My co-worker died from this a few years ago.
He had no symptoms until one morning he came to work and was Homer Simpson yellow.
I called his attention to it. He saw his doctor two days later.
Too late he died within the year.
The exact same thing happened to a co-worker of mine. 6 months. The “yellow death”. He was a good man.
That’s the classic presentation for pancreatic cancer. I worked in diagnostic ultrasound since the 70’s. Every pt I ever saw (100s) that came for a liver ultrasound because they just turned yellow with no other symptoms had pancreatic ca. And the ones I could keep track of usually died within 6 weeks to 3 months.
