Intracellular λ Light Chain Inclusions in Chronic Lymphocytic Leukaemia

Abstract
A [human] case of chronic lymphocytic leukemia (CLL) with intracytoplasmic crystalline inclusions in peripheral blood lymphocytes is presented. The inclusions were identified as crystals of .lambda. L chain and were present in bone marrow derived (B) lymphocytes. The occurrence of L chain crystals in CLL may reflect a more primitive defect in immunoglobulin (Ig) synthesis, intracellular transport or secretion than was previously reported.
