Perform this procedure for staging rather than diagnostic purposes. Bilateral bone marrow aspirate and biopsy should be performed because bone marrow involvement is usually patchy. In bone marrow sections, the neoplastic cells may infiltrate in a focal (ie, paratrabecular or nonparatrabecular, depending on the type of lymphoma), interstitial, or diffuse pattern.
