    Hydroa Vacciniforme-Like T-Cell Lymphoma: A Further Brazilian Case.
    Am J Dermatopathol 2017 Feb 15. Epub 2017 Feb 15.
    Departments of *Dermatopathology, and †Dermatology, Universidade Federal do Pará, Brazil.
    Hydroa vacciniforme (HV)-like lymphoma is a rare, usually fatal Epstein-Barr virus-driven lymphoproliferative disease affecting children from Asia, Mexico, and South America. Cutaneous manifestations imitate HV, a benign photodermatosis in which systemic symptoms are not observed, and spontaneous regression occurs later in adolescence or young adulthood. We report a case of HV-like lymphoma in a 12-year-old girl, descendent from an ancient Amazon indigenous tribe that, as far as we know, represents the second Brazilian case ever reported in the medical literature.

    Int J Hematol 2017 Apr 16;105(4):406-418. Epub 2017 Feb 16.
    Department of Hematology/Oncology, Osaka Medical Center and Research Institute for Maternal and Child Health, 840 Murodo, Izumi City, Osaka, 594-1101, Japan.
    Chronic active Epstein-Barr virus infection (CAEBV) is a prototype of the EBV-associated T- or NK-cell lymphoproliferative diseases, which also include hypersensitivity to mosquito bites and severe-type hydroavacciniforme. The manifestations of CAEBV are often self-limiting with minimum supportive care or only prednisolone and cyclosporine A with or without etoposide. However, allogeneic hematopoietic stem cell transplantation (HSCT) is the only cure, without which patients with CAEBV die within several years. Read More

    Cutaneous EBV-related lymphoproliferative disorders.
    Semin Diagn Pathol 2017 Jan 7;34(1):60-75. Epub 2016 Dec 7.
    Hematopathology, National Cancer Institute (NCI), Bethesda, MD, USA.
    This article will focus on the cutaneous lymphoproliferative disorders associated with EBV, with an emphasis on the upcoming changes in the revised 4th Edition of the WHO classification of tumors of the hematopoietic system, many of which deal with cutaneous disorders derived from NK-cells or T-cells. Extranodal NK/T-cell lymphoma usually presents in the upper aerodigestive tract, but can involve the skin secondarily. EBV-associated T- and NK-cell lymphoproliferative disorders (LPD) in the pediatric age group include the systemic diseases, chronic active EBV infection (CAEBV) and systemic EBV+ T-cell lymphoma of childhood.

    Cooper Medical School of Rowan University, Camden, New Jersey; Perelman School of Medicine at the Hospital of the University of Pennsylvania, Philadelphia, Pennsylvania.
    Epstein-Barr virus (EBV) was the first human virus to be associated with oncogenesis. Over the past few decades, cumulative research has revealed that latent EBV infection may be implicated in the pathogenesis of a heterogeneous group of lymphoproliferative disorders and malignancies occurring in both immunocompetent and immunocompromised hosts. Many of these diseases have either primary or secondary cutaneous manifestations. Read More

    Epstein-Barr virus: dermatologic associations and implications: part I. Mucocutaneous manifestations of Epstein-Barr virus and nonmalignant disorders.
    J Am Acad Dermatol 2015 Jan;72(1):1-19; quiz 19-20
    Cooper Medical School of Rowan University, Camden, New Jersey; Perelman School of Medicine at the University of Pennsylvania, Philadelphia, Pennsylvania.
    Epstein-Barr virus (EBV) is a ubiquitous virus that has been implicated in a wide range of human diseases, many of which have mucocutaneous manifestations. As a member of the herpesviridae family, EBV causes lifelong infection by establishing latency in B lymphocytes. An intact immune response is critical in preventing progression of EBV disease, and the clinical manifestations of infection are dependent on the intricate relationship between virus and host immune system.

    Anti-CCR4 monoclonal antibody mogamulizumab for the treatment of EBV-associated T- and NK-cell lymphoproliferative diseases.
    Clin Cancer Res 2014 Oct 12;20(19):5075-84. Epub 2014 Aug 12.
    Department of Virology, Nagoya University Graduate School of Medicine, Nagoya, Japan.
    Purpose: Epstein-Barr virus (EBV) infects not only B cells but also T cells and natural killer (NK) cells, and T- and NK-cell lymphoproliferative diseases (T/NK-LPD) that are refractory to conventional chemotherapies may develop. To identify a molecular-targeted therapy for EBV-associated T/NK-LPDs, we investigated whether CC chemokine receptor 4 (CCR4) was expressed on EBV-infected T and/or NK cells and whether a humanized anti-CCR4 monoclonal antibody, mogamulizumab, was effective.

    Experimental Design: CCR4 expression was examined in various cell lines. Read More

    Hydroa vacciniforme (HV) and solar urticaria (SU) are uncommon immunologically mediated photodermatoses. HV occurs almost exclusively in children, usually beginning in childhood and remitting spontaneously by adolescence. Association with chronic Epstein-Barr virus infection has been reported in HV, which raises the possibility of lymphoproliferative disorders in these patients. Read More

    Epstein-Barr virus-associated lymphoid malignancies: the expanding spectrum of hematopoietic neoplasms.
    Nagoya J Med Sci 2013 Aug;75(3-4):169-79
    Ubiquitous Epstein-Barr virus (EBV) infects not only B cells but also T and NK cells, and is associated with various lymphoid malignancies. The spectrum of EBV-associated lymphoid malignancies is expanding from Burkitt lymphoma to the newly defined systemic EBV+ T cell lymphoproliferative disease of childhood and hydroa vacciniforme-like lymphoma. However, some EBV-associated malignancies are not defined well and overlap other diseases. Read More

    Current research on chronic active Epstein-Barr virus infection in Japan.
    Pediatr Int 2014 Apr;56(2):159-66
    Department of Infectious Diseases, National Research Institute for Child Health and Development, Tokyo, Japan.
    Epstein-Barr virus (EBV) infection is usually asymptomatic and persists lifelong. Although EBV-infected B cells have the potential for unlimited proliferation, they are effectively removed by the virus-specific cytotoxic T cells, and EBV-associated lymphoproliferative disease develops only in immunocompromised hosts. Rarely, however, individuals without apparent immunodeficiency develop chronic EBV infection with persistent infectious mononucleosis-like symptoms. Read More

    Cutaneous nonmycotic T- and natural killer/T-cell lymphomas: diagnostic challenges and dilemmas.
    J Am Acad Dermatol 2014 Apr 9;70(4):724-35. Epub 2014 Feb 9.
    Department of Pathology, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul, Korea.
    Mycosis fungoides is the prototype of primary cutaneous T-cell lymphoma and is more common in the West than in the East, whereas nonmycotic primary cutaneous T-cell lymphoma is more frequent than mycosis fungoides among Asians. Nonmycotic primary cutaneous T-cell lymphomas comprise several categories of neoplasms and might pose diagnostic challenges because of the rarity of these lesions and overlapping features among certain entities. The authors recommend diagnostic approaches including histopathological evaluation, immunohistochemical markers, and ancillary studies. Read More

    From a clinicopathological conference on nine elderly patients with Epstein-Barr virus (EBV)-associated T/natural killer (NK)-cell lymphoma, we have addressed the patients' backgrounds, clinical manifestations, histopathological findings, cytogenesis, complications and prognoses. Among these elderly patients (>65 years old), seven patients had extranodal NK/T-cell lymphoma, nasal type (ENKL) with an NK-cell phenotype, and two patients had EBV(+) T-cell lymphomas or lymphoproliferative disorders (LPD) with cutaneous lesions mimicking pityriasis lichenoides et varioliformis acuta (PLEVA) or hydroa vacciniforme (HV). No patients had a previous episode of EBV-related symptoms such as infectious mononucleosis, chronic active EBV infection, HV or hypersensitivity to mosquito bites. Read More

    Epstein-Barr virus-associated T/natural killer-cell lymphoproliferative disorders.
    J Dermatol 2014 Jan;41(1):29-39
    Department of Pathology, Ewha Womans University School of Medicine, Seoul, Korea.
    Primary infection with Epstein-Barr virus (EBV) is usually asymptomatic and, in a normal host, EBV remains latent in B cells after primary infection for the remainder of life. Uncommonly, EBV can infect T or natural killer (NK) cells in a person with a defect in innate immunity, and EBV infection can cause unique systemic lymphoproliferative diseases (LPD) of childhood. Primary infection in young children can be complicated by hemophagocytic lymphohistiocytosis or fulminant systemic T-cell LPD of childhood. Read More

    Umbilical cord blood as an alternative source of reduced-intensity hematopoietic stem cell transplantation for chronic Epstein-Barr virus-associated T or natural killer cell lymphoproliferative diseases.
    Biol Blood Marrow Transplant 2014 Feb 2;20(2):214-21. Epub 2013 Nov 2.
    Department of Hematology/Oncology, Osaka Medical Center and Research Institute for Maternal and Child Health, Osaka, Japan.
    Chronic Epstein-Barr virus-associated T/natural killer cell lymphoproliferative diseases represented by chronic active Epstein-Barr virus infection are lethal but are curable with several courses of chemotherapy and allogeneic hematopoietic stem cell transplantation (HSCT). Recently, we reported that reduced-intensity conditioning (RIC) provided better outcomes than myeloablative conditioning because RIC was less toxic. However, it was unclear whether cord blood transplantation (CBT) works in the context of RIC. Read More
