The House M.D. episode about three diagnostic cases is titled “Three Stories.”
It is the twenty-first episode of the first season and originally aired on Fox on May 17, 2005. In the episode, Gregory House gives a lecture to medical students while presenting three apparently separate patient stories.
The structure lets the audience compare the students’ assumptions with House’s diagnostic reasoning. The cases also reveal important information about House’s own history, including the event that caused his chronic leg pain and led to his use of a cane.
“Three Stories” received major critical recognition and won the Primetime Emmy Award for Outstanding Writing for a Drama Series. It is often remembered as one of the show’s most inventive episodes because its flashbacks, teaching format, and personal revelations gradually connect the cases.
