Extranodal adult T-cell leukemia/lymphoma (ATLL) of the head and neck is a rare disease. We studied the clinicopathological features of nine patients with ATLL involving extranodal head and neck sites and conducted a literature review. Six patients presented with extranodal mass of the head and neck, whereas three had disseminated diseases. Tumors involved(More)
BACKGROUND Adult T-cell leukemia/lymphoma (ATLL) is a highly aggressive T-cell lymphoma and etiologically associated with human T-lymphotropic virus type 1 (HTLV-1). Patients with ATLL commonly present with leukemic changes, systemic lymphadenopathy, and/or extranodal lesion and have very poor prognosis. METHODS AND RESULTS We describe a rare case of ATLL(More)
A new cell line, STR-428 was established from ascites tumor cells of a malignant effusion lymphoma patient without human herpes virus-8 (HHV-8) infection. STR-428 cells showed an immunophenotype of mature B-cells and produced few cytokines related to lymphomatous effusion. Karyotypic and genetic analysis revealed complex translocations including(More)
Primary extranodal involvement of Hodgkin lymphoma (HL) is rare. We report two HL patients presenting with exclusive or predominant lung involvement. In both cases, the results of transbronchial and/or CT-guided lung needle biopsy were indicative of granulomatous disease. Eventually, lymph node biopsy specimens revealed HL with nodular sclerosis type and(More)
We report a rare case of human immunodeficiency virus (HIV)- and human herpes virus-8 (HHV-8)-negative primary effusion lymphoma (PEL)-like lymphoma presenting with lymphomatous effusions complicated by cardiac tamponade. A 68-year-old woman was hospitalized with generalized weakness in June 2006. Echocardiogram revealed the presence of pericardial effusion(More)
We report a Japanese case of human herpes virus-8 (HHV-8)-associated multicentric Castleman disease(MCD) complicated by hemophagocytic syndrome(HPS). A 60-year-old man presented with persistent fever and progressive pancytopenia in June 2004. On physical examination, anemia, icterus, hepatosplenomegaly, and generalized lymphadenopathy were detected.(More)
We report a rare case of primary cutaneous diffuse large B-cell lymphoma (DLBCL) with Burkitt-like morphology. A 54-year-old man presented with multiple subcutaneous tumors. Pathological examination showed morphological features resembling Burkitt or Burkitt-like lymphoma (BL/BLL) with high MIB-1 positivity. Cytogenetic studies revealed no 8q24/c-myc(More)
