Undifferentiated Pleomorphic sarcoma

Has anyone been diagnosed with undifferentiated pleomorphic sarcoma?  

mine came up overnight the size of a baseball on the back of my left elbow. no pain, swelling or dicoloration. first doctors prelim diagnosis was possible severe ssprain and severe hematoma i was sent for an mri with contrast. a rariologist concured with diagnosis. i was operated on and after 2 hours closed up but the tumor was violated and possible seeding. i was referred to a surgical orthopedic oncologist in jackson ms..prior to 2nd surgery radiation for 5 weeks. the tumor was shrinking but 2 days after the last treatment it fought back and started to grow. i spent over 10 hours in or, apparently my tumor refused to die and got a new blood supply, my artery, a vascular surgeon resectioned it and the tumor was removed "well within the  margins"spirits were very high there was no matistisis yet and a follow up ct and mri were scheduled for 3 months later.june 27 the tests were done and results showed matistisi 5mm upper left lung lobe and 8mm upper right lobe with 9 others that were too small to measure. i have an appointment with an oncologist july 10th to discuss options. i'm 74 in better than good shape ,never taken a drop of medicin, and other than the flu never sick. prognosis does not look good
