I thought Peter Pan syndrome was more innocuous. Men refusing to grow up

Yes. But,
What I meant was Narcissistic personality. I think you get the idea.

When I searched the internet for "Peter Pan Syndrome" I saw a very similar definition with NPD. And the page redirected me to the description of "Narcissistic Personality Disorder."

I think both are related to childhood trauma. But NPD's effects can start in every age of life.

Why some adults never outgrow childhood?

There can be many reasons for this. But it can also be due to reasons beyond the control of the person himself/herself.
Example:
NPD, a condition that is common in psychology today. A person with NPD assigns specific roles to their children. After all, the "adult child" structure is a common feature in that person's children. 
Today, NPD is thought to be in 6 out of every 100 people.
