"Full Frontal" host Samantha Bee apologized for a segment on her TBS show Wednesday night that made fun of a man's haircut.

In the segment about this year's Conservative Political Action Conference (CPAC), Bee mocked an attendee saying his haircut resembled a Nazi.

"This year, the bow ties were gone, replaced by Nazi hair, Nazi hair, Nazi hair," the video narrates while focusing in on 20-year-old student Kyle Coddington.

It turns out, Coddington has a partially-shaved head because he is battling brain cancer.

"When @iamsambee makes fun of your brother for having 'Nazi hair,'" Coddington's sister tweeted at the comedian. "He actually has stage 4 brain cancer, but whatever floats your boat."

Bee issued an apology on Twitter and removed the segment from her YouTube page.

@meg_kelly16 We deeply apologize for offending you and @_that_kyle. We only learned of his condition today & have removed him from the piece — Samantha Bee (@iamsambee) March 9, 2017

According to Coddington's GoFundMe page, he has stage 4 glioblastoma, an aggressive form of brain cancer.

"Currently, there is no cure, but there is a chance. The doctor said it all depends on how hard we go after it, and how my body responds to the treatment," he wrote. "I fully believe that God is still in the miracle-making business as well! I'm putting complete trust in God and I know regardless of the outcome, I'll be healed one way or another! Please continue to keep me in your thoughts and prayers. Thanks ya'll!"
