problem with comparing a part of string with whole string

'grep' will tell you if there is a match in the string;
x <- c("*RIGHT, EPICARDIUM: FOCUS, GRAY-WHITE, SINGLE, APPROX 0.6 CM IN DIAMETER*.","*MEDULLRY TUMOR BENIGN,TYP PHEOCHROMOCYTOMA*")
grep("GRAY-WHITE", x)
[1] 1
grep("TUMOR BENIGN", x)
[1] 2

Hi all,

I got one problem with comparing strings like if any string is like

"*RIGHT, EPICARDIUM: FOCUS, GRAY-WHITE, SINGLE, APPROX 0.6 CM IN DIAMETER*."

and i have to compare       "*GRAY-WHITE*"        with the above string

or otherwise   i have to compare       " *TUMOR BENIGN*"       this string
with

"*MEDULLRY TUMOR BENIGN,TYP PHEOCHROMOCYTOMA*"

i tried with split and compare but its not working
