I have very high TSH (68), free T4 is 1.16, which is in the normal range. I have persistent weight loss, lack of appetite. Today I vomited twice. I have a extramedullary plasmacytoma in my gum. Biopsy said CD 79A and Lambda were strongly positive, CD 138, Cd 3 and Kappa were focally positive in a small number of cells, CD 20 was negative. Radiation therapy scheduled for tomorrow was put off so I could get another biopsy. MRI, PET, CT scans bone marrow test show no cancer cells anywhere. The growth in my gum was painful and swollen when I got my first biopsy, but how it only looks different , is not swollen and without pain. I am taking Keppra to prevent seizures, have started prilosec 6 days ago to reduce GERD. I am a 78 year old male. I am trying to make an appointment with an endocronologist. Heart and many other tests are normal Should I be doing anything else? T3 and other blood test results have not arrived yet. Protein electrophoresis shows polyclonal gammopathy.
