A case report of human immunodeficiency virus-associated anaplastic lymphoma kinase protein-negative anaplastic large cell lymphoma

Abstract

Human immunodeficiency virus (HIV)-associated anaplastic large cell lymphoma (ALCL) is not so common, and anaplastic lymphoma kinase protein (ALK)-negative ALCL is rare and has a low survival rate. We report a case of a 31-year-old Japanese man diagnosed with HIV-associated ALK-negative ALCL who presented with long-lasting fever of unknown origin. The diagnosis was based on a full work-up that included inguinal lymph-node biopsy. Eightcycle chemotherapy that included cyclophosphamide, doxorubicin, vincristine, and prednisone in addition to antiretroviral therapy for HIV infection provided a complete remission of his ALCL and over 5-year survival for him. © 2013 Taniai et al.
