Help In Identifying Disorder

I am frustrated with the whole medical establishment! My dad (87) has been in the hospital for twelve days. Symptoms in the past six months have been: upper body rash with severe itching - never diagnosed, went away; severe weight loss; reflux-like gag and choke on occasion while swallowing, says things seem to get 'stuck'; serious anemia (count at nine a few months back, (bone marrow tests showed no evidence of leukemia) less than six when he was admitted to the hosp, took four units of whole blood to stabilize him); endoscopy and colonoscopy only showed 'some erosion'; ct scans show a mass on the neck of the pancreas but blood tests (my research didn't say there were any blood tests for this) don't support pancreatic cancer; too weak at this point for a biopsy as all of their poking has left him with phlebitis and blood clots in both arms and leg; depression (gee, I wonder why!) and now just an all over body ache and sensitivity to touch. He has had severely dry eyes and macular degeneration for years. Prostate cancer treated with radium? Implants about ten years ago. Now just has the usual urinary urgency and occasional leaking. Does all of this add up to anything that anyone has ever heard of? Lupus and fibromyalgia both came to my mind but neither one usually includes the severe anemia. Any thoughts are welcome. Thanks :?
