I have a bone marrow biopsy on a 63 yr old male with severe peripheral
pancytopenea. Biopsy is atypical lymphoid infiltrate consistent with NHL
small cleaved cell. Light scatter shows a single population of small
lymphocytes. The phenotype is CD5-, CD19+, CD22+, CD10-, CD20+, CD25-,
CD23-, CD103-, CD11c-, kappa bright positive, lambda negative. Seems to fit
best with follicular lymphoma except for the CD10 negativity. I wonder what
others of you may think about this phenotype?
Thanks,
