What is the name of House M.D.’s first-season episode about three medical cases?

The first-season House M.D. episode about three medical cases is titled “Three Stories.”

In the episode, Gregory House lectures medical students about diagnosis by presenting three apparently separate patient cases. The stories demonstrate how symptoms can mislead doctors and how a diagnosis depends on testing assumptions as well as recognizing patterns.

The episode’s unusual structure makes it stand out from the show’s more conventional case-of-the-week format. Its final story connects the lesson to House’s own past, providing important context for his chronic pain and difficult personality without making the episode simply an origin story.

“Three Stories” aired during the first season and was written by David Shore. It is often cited as one of House M.D.’s best episodes and should not be confused with “One Day, One Room,” another season-one episode involving a distinctive patient relationship.
