I just checked back chapter 19 from Tokyo Ghoul and coincidentally that weird scar is around the same location where he got one from Rize's date.

I don't remember at what chapter we saw Haise's stomach, but either Ishida forgot to draw the scar from before or it magically disappeared.

TL;DR: Arima and Rize really are siblings since both decided to impale Kaneki in the same spot so he literally is scarred for the rest of his life.
