This word is constant. Did you forget the $ on a variable?
Problematic code
case foo in
  bar) echo "Match"
esac

Correct code
case $foo in
  bar) echo "Match"
esac

Rationale
You are using a case statement to compare a literal word.
You most likely wanted to treat this word as a $variable or $(command) instead.
Exceptions
None
