Yeah, we've been explicitly told by Eto that a person can manipulate the appearance of their kagune if they're intelligent/imaginative enough.

Eto made her kakuja something HUGE SCARY, when she herself is very tiny. Yoshimura likely mimicked her to the best of his ability, and them being parent/child made any markings left behind a close match.
