title: Pseudo-Gaucher cells preceding the appearance of immunoblastic lymphoma.
abstract: A 49-year-old white woman who presented with multiple lytic bone lesions was found to have Gaucher-like storage cells in multiple bone marrow aspirates and a percutaneous bone marrow biopsy several months before the development of overt disseminated lymphoma. Open bone biopsies of three different sites at initial presentation revealed only necrotic debris and a nondiagnostic polymorphic infiltrate. Elevated leukocyte beta-glucocerebrosidase levels ruled out the diagnosis of classic Gaucher's disease. The ultrastructural characteristics of these storage cells were found to be identical to those of pseudo-Gaucher cells found in patients with chronic myelogenous leukemia and distinctly different from those previously reported in other non-Hodgkin's lymphoma or plasma cell dyscrasias. A possible pathogenetic mechanism is suggested.
