If you can't aspirate it, then you remove one for microscopic
examination.  Retrobulbar masses, if there really is one, are most
commonly lymphoma (it is not an uncommon site for development of the
tumor.) Usually, though, lymphoma can be aspirated.  A rock had mass on
the skull may be an osteoma, a benign tumor of bone (and something that
can easily be demonstrated on an X-ray.)
 
I can't tell if all of the tumors are related here, or if you may
coincidentally have a couple coming up at the same time.  Osteomas are
fairly slow-growing, though.
 
Best course of action - X-ray of the head right before excision of one of
the tumors.
 
I would be happy to look at the samples it you would care to send
them to me - this sounds like an interesting case.
 
With kindest regards,
