Subsequent development of diffuse large B-cell lymphomas and hodgkin lymphoma associated with primary immune disorder in a 6-year-old female: A case report and review of the literature

Abstract

Neoplastic lymphoid proliferation may arise from immune deficiency or disordered regulation of the immune system. Often the neoplasms are associated with viral agents, such as Epstein-Barr virus, human immunodeficiency virus, or human herpes virus 8. Lymphoproliferative diseases have been documented in a variety of primary immune disorders. The most commonly encountered neoplastic lesion is diffuse large B-cell lymphoma (DLBCL), although Hodgkin lymphoma (HL), Burkitt lymphoma, and peripheral T-cell lymphomas and/or leukemias have also been documented in rare instances. We report a case of a 6-year-old girl with unclassifiable primary immunodeficiency diagnosed with 2 different clones of DLBCLs and subsequently developed lymphocyte-depleted, classical HL. Both neoplasms were associated with Epstein-Barr virus. To the best of our knowledge, this is the first reported occurrence of primary immune disorder-associated lymphoproliferative disease with sequential development of DLBCLs and HL in a pediatric patient. Thorough surveillance is paramount for accurate assessment of the associated lymphoproliferative disease and in ascertaining likely transformation to, or de novo evolution of a different lymphoid neoplasm. This is also important in evaluating treatment response with appropriate therapeutic adjustments if clinically indicated. © 2011 Lippincott Williams & Wilkins, Inc.
