Morphology

peristomal = stomal (semi-transparent) = peri + stoma + al

The meaning is directly built from 'peri-' plus 'stomal' to mean around or surrounding a stoma.

Etymology

The word peristomal comes from the Greek parts peri- meaning 'around', like in perimeter, and stoma meaning 'mouth' or 'opening'. So peristomal means the area 'around an opening', which is why doctors and biologists use it for the skin or tissue that surrounds a stoma.
