Immunophenotypic profile and role of adhesion molecules in splenic marginal zone lymphoma with bone marrow involvement

2005

Abstract Splenic Marginal Zone Lymphoma (SMZL), with or without villous lymphocytes (VL+/-), is a low-grade lymphoproliferative disorder with constant involvement of the bone marrow (BM). Different BM infiltration patterns, mainly intra-sinusoidal, interstitial and nodular, have been described. Adhesion molecules (AMs) constitute a heterogeneous group of antigenic receptors playing a major role in leukocyte recruitment, in lymphocyte homing and in cellular-mediated immune response. Evolution and pattern of the BM infiltrate could be influenced by a variable expression of AM on SMZL lymphocytes. The degree and pattern of BM infiltration and the immunohistochemical expression of AM (H-CAM, BL…
