we have used these genetic markers in three ways : to establish a diagnosis of lymphoma in a neoplastic disorder of uncertain cell type , to show that some lymphomas that were previously classified as being of t-cell type in fact contain monoclonal b cells , and to detect clonal b-cell populations within lymphomatous tissues of uncertain immunotype and within an atypical lymphofollicular hyperplasia having no other clonal surface markers .
