I recommend you take a look at (info "(elisp)Multiline Font Lock").

Also in some cases, you can use syntax-propertize-function instead, to
mark the whole construct as a kind of comment or string.  Then use
font-lock-syntactic-face-function to highlight the block with
a particular face (if the default string-face or comment-face is not
good enough).  And then in font-lock-keywords, you can match "word that
is not made by underscores" and use (syntax-ppss) to decide whether it's
within a /MASK block or not to decide how to highlight it.
