Concurrent CD5-negative small lymphocytic lymphoma (SLL) and CD5-positive metastatic carcinoma of unknown primary in a lymph node biopsy
Journal of Hematopathology - Tập 6 - Trang 45-50 - 2012
Juehua Gao, LoAnn Peterson, Yanming Zhang, Yi-Hua Chen
CD5 expression is considered a key marker for the diagnosis of chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL). We report an unusual case of CD5-negative (CD5−) SLL with a concurrent CD5-positive (CD5+) adenocarcinoma of unknown primary involving the same lymph node. An 83-year-old woman with a history of CD5− B cell lymphoma diagnosed on a core biopsy of a cervical lymph node pr...... hiện toàn bộ
Primary lymphomatous presentation of hairy cell leukemia as osteolytic vertebral lesions: a case report
Journal of Hematopathology - - 2018
Jinming Song, Hailing Zhang, Xiaohui Zhang, Lynn Moscinski, Haipeng Shao
Hairy cell leukemia (HCL) is a rare and indolent mature B cell neoplasm. Most patients with HCL have excellent response to purine analogs and BRAF inhibitors. Therefore, it is clinically important to identify and differentiate HCL from other B cell neoplasms. HCL is predominantly found in the peripheral blood, bone marrow, or spleen. HCL presenting initially or solely in unusual sites is extremely...... hiện toàn bộ
Leishmania interaction with an osteoclast
Journal of Hematopathology - Tập 12 - Trang 105-106 - 2019
Flávio A. Naoum
Visceral leishmaniasis is caused by an intracellular protozoan parasite, Leishmania donovani. Frequently, a bone marrow aspirate can confirm the diagnosis by showing intracellular forms of Leishmania amastigotes in macrophages. Here we present a unusual interaction of Leishmania with an osteoclast in the bone marrow.
Aberrant expression of CD56 on granulocytes and monocytes in myeloproliferative neoplasm
Journal of Hematopathology - Tập 6 - Trang 127-134 - 2013
Ping Gong, Fernanda Metrebian, Alina Dulau-Florea, Zi-Xuan Wang, Renu Bajaj, Gene Gulati, Stephen C. Peiper, Jerald Z. Gong
We reviewed CD56 expression on bone marrow (BM) granulocytes and monocytes by flow cytometry in 101 cases of myeloproliferative neoplasm (MPN) and compared them with those from 42 cases of myelodysplastic syndrome (MDS), 47 cases of negative BM after stem cell transplantation, and 24 cases of negative BM after chemotherapy. Forty cases of negative staging BM for lymphoma were used as negative cont...... hiện toàn bộ
Erratum to: Two morphologically and immunophenotypically distinct cell populations within a composite lymphoma arise from a common precursor
Journal of Hematopathology - Tập 4 - Trang 183-183 - 2011
Harry Zhang, Hossein Salimnia, Gail Bentley, Weimin Liu, Michele Phillips, Gerald L. Feldman, Margarita Palutke
A rare case of fluid overload-associated large B-cell lymphoma and antigen loss at relapse
Journal of Hematopathology - Tập 16 - Trang 235-240 - 2023
Xue Yan, Bin Chen, Hongxia Jing, Zhinan Yang, Ting Zhang, Yani Lin, Jinning Shi
Fluid overload-associated large B-cell lymphoma (FO-LBCL) is a new addition to the list of large B-cell lymphomas in the 5th edition of the World Health Organization Classification of Haematolymphoid Tumours (WHO-HAEM5). This report presents an unusual case of FO-LBCL with partial B cell antigen loss at relapse and reviews the characteristics, treatment, and prognosis of these patients to enhance ...... hiện toàn bộ
Novel developments in the pathogenesis and diagnosis of extranodal marginal zone lymphoma
Journal of Hematopathology - Tập 10 - Trang 91-107 - 2017
Max I. Schreuder, Michiel van den Brand, Konnie M. Hebeda, Patricia J. T. A. Groenen, J. Han van Krieken, Blanca Scheijen
Extranodal marginal zone lymphoma (EMZL), mostly represented by mucosa-associated lymphoid tissue (MALT) type, also referred to as MALT lymphoma, is a clinically heterogeneous entity within the group of low-grade B cell lymphomas that arises in a wide range of different extranodal sites, including the stomach, lung, ocular adnexa, and skin. It represents the third most common non-Hodgkin lymphoma ...... hiện toàn bộ
Ectopic extra-nodal in situ follicular neoplasia (ISFN)

Epstein–Barr virus expression in plasma cell neoplasms and its association with plasmablastic morphologic features
Journal of Hematopathology - Tập 6 - Trang 213-218 - 2013
Whitney Pasch, William Wu, Dylan Bach, Nagesh Rao, Xiaohui Zhao, Sherif A. Rezk
Plasma cell neoplasms include plasma cell myeloma, plasmacytoma, primary amyloidosis, and light and heavy chain deposition diseases. Epstein–Barr virus (EBV) expression has rarely been reported to be associated with plasma cell neoplasms except for patients with a previous history of transplantation or severe immunodeficiency. In contrast, EBV expression has been reported in the majority of plasma...... hiện toàn bộ
Intracytoplasmic basophilic bodies in leukocytes in an HIV patient with pleural and pericardial effusion led to unexpected diagnosis
Journal of Hematopathology - Tập 10 - Trang 35-38 - 2017
Hector Mesa, Kristine Hummel, Susan Dachel, Juan C. Manivel
Human immunodeficiency virus (HIV) infections are declining worldwide; however, there are still >1.2 million HIV-infected people in the USA and ~6700 deaths/year can be directly attributed to HIV-related diseases. Opportunistic infections, Kaposi sarcoma, and non-Hodgkin lymphomas are always high in the differential diagnosis of HIV patients with systemic symptoms; however, causes of morbidity and...... hiện toàn bộ
