An actor from The Sopranos is speaking out about the rare medical condition that shaped his career.

Max Casella, 59, talked about his “humiliating” experience with pituitary dwarfism at an Oct. 20 screening of Jimmy, telling Page Six that he did not go through puberty until 27 as a result.

The actor originally established his career playing characters significantly younger than he was, portraying a teenage Vinnie Delphio in the ‘90s sitcom Doogie Howser, M.D. while in his twenties.

“I had to start all over again. It was a humiliating experience,” Casella, who played Christopher Moltisanti’s crew member Benny Fazio in The Sopranos, said.

Casella has previously revealed that he was given testosterone to treat his condition, which is also known as growth hormone deficiency.

Pituitary dwarfism, a relatively rare condition affecting an estimated 1 in 3,000 to 4,000 children, causes the body to produce an insufficient amount of growth hormone, leading to shorter stature and delayed physical development.

“I have a malfunctioning pituitary gland from birth and basically had to jumpstart my puberty by pumping me full of testosterone and growth hormones,” he said in 2022, noting that he had not “even shaved” by 25.

Continuing, “You know what happens to especially boys when they go through puberty. They get awkward and zits and fat, chubby, whatever.”
