How would you use "case in point" in a sentence? In that sentence, the whole phrase, "case in point," would be considered a noun. Is that correct?
Do you mean something like the following passage?
I saw it somewhere several days ago and am not sure whether 'a case in point' should be regarded as a noun phrase or 'a case' is a noun phrase modified by 'in point'.

A case in point is how Western culture inherited a combination of myths
from the Greeks, whose fertile imagination had interpreted natural and
spiritual events in an animistic and anthropomorphic way. Plato described
mythos as a tale revolving around gods, divine beings, heroes, and those
returned from the afterlife. This was opposed to logos, the typical
rational argumentation of philosophical speculation. A myth is, therefore,
a story or a series of tales that has often reached us in a fragmentary way.
