Magnetic resonance imaging (MRI) showed an oval-shaped mass in the right psoas major muscle. The mass showed high intensity on T1-, T2-, and diffusion-weighted imaging and mimicked an acute-phase hematoma. Read More

    Donor-Derived Smoldering Multiple Myeloma following a Hematopoietic Cell Transplantation for AML.

    Posttransplant Lymphoproliferative Disorder (PTLD) is one of the most common malignancies complicating solid organ transplantation. In contrast, PTLD accounts for a minority of secondary cancers following allogeneic hematopoietic cell transplantation (HCT). Here we report on a 61-year-old woman who received an ABO-mismatched, HLA-matched unrelated donor hematopoietic cell transplantation from a presumably healthy donor for a diagnosis of acute myeloid leukemia (AML).

    Hematology & Oncology Associates of Northeastern Pennsylvania, 1100 Meade Street, Dunmore, PA 18512, USA.
    The MYD88 L265P somatic variant (MYD88) has a high prevalence in Waldenstrom's Macroglobulinemia (WM), a form of lymphoplasmacytic lymphoma (LPL) associated with monoclonal IgM. Although the role of MYD88 in WM was initially reported in 2012, it was not until 2016 that MYD88 testing was included in the National Cancer Care Network (NCCN) Guidelines. We present a case illustrating the utility of MYD88 status in distinguishing atypical forms of WM from marginal zone lymphoma (MZL) and in selecting second-line therapy with ibrutinib. Read More

    HHV8/EBV Coinfection Lymphoproliferative Disorder: Rare Entity with a Favorable Outcome.

    Pathology Department, Mohamed Tahar Maamouri Hospital, Mrezga, Nabeul, Tunisia; Medicine Faculty of Tunis, Tunis El Manar University, Tunis, Tunisia.
    HHV8/EBV-associated germinotropic lymphoproliferative disorder (GLD) is a challenging diagnosis given its rarity, the particular clinical presentation, and the lack of expression of markers usually used in establishing hematopoietic lineage. We report a new case of HHV8/EBV GLD in an immunocompetent 78-year-old woman. The diagnosis was made in an incidentally discovered lymphadenopathy. Read More

    Synchronous Occurrence of Chronic Myeloid Leukemia and Mantle Cell Lymphoma.
    Case Rep Hematol 2017 8;2017:7815095. Epub 2017 Feb 8.
    Division of Hematology and Oncology, Department of Medicine, University of Florida, Gainesville, FL, USA.
    Chronic myeloid leukemia (CML) and mantle cell lymphoma (MCL) are hematologic malignancies that originate from different oligopotent progenitor stem cells, namely, common myeloid and lymphoid progenitor cells, respectively. Although blastic transformation of CML can occur in the lymphoid lineage and CML has been related to non-Hodgkin lymphoma on transformation, to our knowledge, de novo and synchronous occurrence of CML and MCL has not been reported. Herein, we report the first case of synchronous CML and MCL in an otherwise healthy 38-year-old man. Read More

    Spontaneous Heparin-Induced Thrombocytopenia and Venous Thromboembolism following Total Knee Arthroplasty.

    A 72-year-old Caucasian woman was admitted for an elective left total knee arthroplasty. Her surgery was uncomplicated and she was discharged to a rehabilitation facility. Twelve days later, she developed acute shortness of breath followed by a syncopal episode. Read More

    Myelodysplastic Syndrome Clinically Presenting with the "Classic TTP Pentad".
    Case Rep Hematol 2017 1;2017:4619406. Epub 2017 Feb 1.
    Department of Hematology and Oncology, The Brooklyn Hospital Center, 121 Dekalb Ave, New York, NY 11201, USA.
    The clinical presentation of myelodysplastic syndrome (MDS) is not specific. Many patients can be asymptomatic and can be detected only due to an abnormal complete blood cell count (CBC) on routine exam or for other reasons while others can be symptomatic as a consequence of underlying cytopenias. Thrombotic thrombocytopenic purpura (TTP) usually is suspected under the evidence of microangiopathic hemolytic anemia (MAHA) and thrombocytopenia and because it is a life-threatening condition (medical emergency) immediate initiation of plasmapheresis could be life-saving.

    Department of Pathology, Soroka University Medical Center and Faculty of Health Sciences, Ben-Gurion University of the Negev, Beer-Sheva, Israel.
    An elderly woman presented with generalized lymphadenopathy, several systemic symptoms, and splenomegaly. An inguinal lymph node excision revealed a compound picture. One aspect of the lymph node morphology, including cells with follicular T-helper cell phenotype, was most consistent with angioimmunoblastic T-cell lymphoma. Read More

    Hodgkin Lymphoma and Castleman Disease: When One Blood Disease Can Hide Another.
