horrifies

KIM Kardashian has baffled fans with a mysterious indentation on her back in new photos from her trip to Rome.

The Skims mogul, who just turned 46 this month, debuted what followers called a “backgina” in a polka-dot strapless dress worn at her All’s Fair photoshoot in Italy on October 26.

In her Instagram carousel on Monday, Kim showed off her daring cut-out gown by designer Galia Lahav and styled by Zendaya’s BFF Law Roach.

In one shot where Kim faced away from the camera, fans spotted a strange, deep dent in her back.

One follower cheekily called the mark a “backgina,” seemingly in response to her infamous “pitgina” in 2025.

“What am I looking at?!” one Reddit follower marveled.

“I’m so confused,” another chimed in.

But Kim’s friends, family and Instagram followers largely loved her unusual look.

“The queen diva has arrived!” Kim’s sister Khloe marveled.

“Really love this,” gushed friend Lala Anthony.

Last summer, Kim shocked fans with what they called a “pitgina” in a very tiny bandeau top.

As she waved to onlookers in Venice, a deep indentation in her armpit could be seen.

“Why does it look like a belly button?” one follower asked on a Reddit thread.

“What is that? I’m terrified!” said a second.

New York-based plastic surgeon Dr. Norman M. Rowe, M.D. told The U.S. Sun that the dent could be an “axillary hollowing.”

“An axillary hollowing is essentially a divot or indentation in the armpit area that can result from certain cosmetic procedures,” Dr. Rowe said.

“The most common causes include liposuction to the upper arm or armpit, an arm lift or brachioplasty, or breast augmentation when the implant is placed through the transaxillary route—that is, through an incision in the armpit.

“In these procedures, tissue is removed or repositioned in a way that can leave behind visible contour changes, especially in someone lean like Kim Kardashian.”

Kim has not commented on the “pitgina” or “backgina” talk, or accusations she underwent liposuction procedures.
