T-Lymphoid markers positive

Welcome, but very sorry to hear of your worries. Was the flow cytometry performed on a sample of the mass? If so, then it may point to a lymphoid malignancy, or it may point to T-Lymphocyte involvement in some other condition, T-Cells being a crucial part of the immune system. As well, normal individuals can have the double positive T-Cell markers, but this may point to a problem with his thymus, which the body uses as a "training c enter" for T-Lymphocytes to do their job. Further testing will need to be done. This may include F.I.S.H. testing pr even genomic sequencing on the biopsy cells.

T-Cell malignancies can be extremely difficult to properly identify. There are about 28 varities of T-Cell Lymphomas/Leukemias, and they are quite different from each other. The structure if the mass is also important. If it is an enlarged lymph node, it could signify an infectious process or other immune system activation. Has he had any vaccinations recently? They all provoke an immune response and this response can be normal, even desirable. As I mentioned, further testing is needed and the mass itself, as well as his general health, should be closely monitored.

"Normally" when cancerous T-Lymphocytes are found in the blood, it indicates a leukemia. Otherwise, it might indicate a condition known as a "Lymphoproliferative disease, whhich might not be canc erous. Or, it coujld be an advanced lymphoma. Was he truly sick, or was this blood test for some other reason? Even so, I have been at stage IV with two different T-Cell Lymphomas, the first time in 2008 and the second in 2014-2015. Lymphoma is treatable at all stages and late stage lymphoma is usually when it is found in the body. I am praying for your brother!

Keep the hope up. Even rare and aggressive lymphomas are survivable. First, let us hope that it is something else, but even if, there is much support and many resources.
