main difference is in the complexity of the layout. Analog are more complex than RF layout. But you have to very care ful while designing the RF Layout, as it can really make you cry if you dont follow basics of RF layout.
I will soon Upload the articles and Marterials for you.
Analog layout primarily values matching, symmetry, dummies
to minimize errors from lithography, proximity, thermal
influences.
RF layout tends to have little concern for DC accuracy,
but a lot for coupling and losses, impedance matching
and things of that sort. When you get to tens of GHz it's even
crazier as geometry becomes on the order of wavelength.
tens of GHz: 3cm .. 3mm (ok, vacuum light speed)
RFIC core dimensions: say several 100µm .. 100nm
You're right, however, as the connections to the pads and to the pins have to be considered.
at such high frequency, your trace might behve as transmission line rather than lumped one....leading to transmission line behaviour.....
more inductive at high frequecy.. you mighnt need EM simulaiton to check for the post layout performance...
grounding is more important in RF layout.. preferably true(substrate) ground.....

as said by deepak, at higher frequency , your interconnect will act as an transmission line. You have to follow the rules according to the transmission line. If your design need the lesser noise then you should model the corners very well.
