A 37-year-old man died after being dumped at a Queens hospital under mysterious circumstances, police said Monday.

Cops received a 911 call about 10:30 p.m. Sunday from medical personnel at Elmhurst Hospital, who told them the man had been taken there by somebody who did not stick around.

Doctors worked on the man but he could not be saved. His name was not immediately released.

The victim had no visible signs of trauma, police said.

A city Medical Examiner autopsy will determine how he died. It’s not yet clear if he was the victim of foul play and no arrests have been made.
