Introduction: Histiocytic necrotizing lymphadenitis (or Kikuchi-Fujimoto disease) frequently occurs in Asian young adult females and typically presents as cervical lymphadenopathy with unknown etiology. Although large immunoblasts frequently appear in Kikuchi-Fujimoto disease, the diffuse infiltration of these cells can cause difficulty in establishing a differential diagnosis from lymphoma. In such cases, CD30 immunostaining may be used
however, the extent or distribution pattern of CD30-positive cells in Kikuchi-Fujimoto disease remains largely unknown. Here we investigated the expression of CD30 and its clinicopathologic significance. Materials and Methods: We investigated 30 Kikuchi-Fujimoto disease and 16 control [6, systemic lupus erythematosus (SLE)
10, reactive lymphoid hyperplasia (RLH)] cases. Results: The number of CD30-positive cells in Kikuchi-Fujimoto disease was significantly more than that in SLE and RLH, and majority of these cells were located around necrotic areas. Moreover, double immunohistochemical staining showed these CD30-positive cells to be CD8-positive cytotoxic T cells, suggesting that activated cytotoxic T cells around necrotic areas are a characteristic feature of this disease. Clinicopathologic analysis showed that cases with abundant CD30-positive cells were predominantly female with only mild symptoms and normal laboratory data. Conclusions: In Kikuchi-Fujimoto disease cases, CD30-positive cytotoxic T cells were abundant around necrotic areas
this histologic feature may be helpful to differentiate this disease from SLE and RLH.

Reactive lymphoid hyperplasia(RLH)は、組織学的に胚中心を伴うリンパ濾胞の反応性過形成を示し、個々のリンパ球の異型が少なくpolyclonalな増殖を認めるものと定義される。今回我々は、IgG4陽性形質細胞の集簇を認めた鼻腔底RLHの一例を経験した。症例は69歳女性。主訴は左鼻腔腫瘤、右難聴。右難聴で近医受診した際に、左鼻腔底前方に隆起性病変を認めた。唾液腺腫脹や鼻症状は認めなかった。IgG4値は45.5mg/dlと正常範囲内であった。2度の生検を施行し悪性リンパ腫の可能性も否定できず、摘出術を施行した。病理組織所見は、HE染色では、粘膜上皮下に著明なリンパ球・形質細胞の浸潤を認め、リンパ濾胞の過形成を伴っていた。免疫染色では、濾胞間に多数のIgG4陽性形質細胞を認め、400倍1視野あたり100個を超え、IgG4/IgG陽性細胞比は40%を超えていた。しかし、線維化の所見や高IgG4血症を認めず、包括診断基準に照らしIgG4関連疾患には合致しなかった。摘出後、約1年を経過するが、再発所見を認めていない。今後、病変の再発や悪性転化する可能性も考えられることから、治療後も厳重な経過観察を行う必要があると考えられる。(著者抄録)

AimsThe central nervous system (CNS) is a rare primary site of non-Hodgkin lymphoma. Although direct invasion of nasal natural killer (NK)/T cell tumours into CNS is reported occasionally, primary CNS NK/T cell lymphoma is extremely rare, and the clinicopathological features of primary CNS NK/T cell lymphoma remain largely unknown.
Methods and resultsWe identified four cases from our consultation files and analysed the clinicopathological features. Three were immunocompetent and one was immunosuppressed. There were three males and one female and their ages ranged from 21 to 77 years (median: 46 years). Radiotherapy was rendered for all patients, and methotrexate was administered to two patients. The overall survival was 4-29 months (median, 19 months) for the three immunocompetent patients. Neoplastic cells exhibited medium to large atypical nuclei. Angiocentric growth and necrosis were observed. The immunophenotype was typical of NK cell tumours: CD3 epsilon, 100%; CD56, 67%; CD5, 50%; cytotoxic molecules, 100%; Epstein-Barr virus encoded small RNA (EBER), 100% and T cell receptor (TCR)- or , 0%. No TCR-gene rearrangements were detected. Reviewing 10 additional cases from the literature and comparing with extranasal NK/T cell lymphoma of the more frequent origins (skin or gastrointestinal tract), primary CNS NK/T cell lymphoma was diagnosed at an earlier stage without B symptoms but exhibited aggressive clinical behaviours.
ConclusionsAlthough extremely rare, primary CNS NK/T cell lymphoma does occur and should always be included in the differential diagnosis and we should apply relevant markers routinely in conjunction with exploring the patient background. The accumulation of cases is indispensable to establish an effective treatment strategy for this rare and aggressive malignancy.

We herein report a case of primary parotid extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) with Dutcher bodies. An 82-year-old man presented with a 4 cm x 2.5 cm mass in the left parotid region. Positron emission tomography/computed tomography (PET/CT) showed localized abnormal fluorodeoxyglucose (FDG) uptake in the left parotid gland and lymph nodes of the left cervical region. Fine needle aspiration (FNA) cytology of the left parotid gland showed lymphoplasmacytoid cells with periodic acid-Schiff (PAS)-positive Dutcher bodies. A subsequent excisional biopsy showed sheets of small- to medium-sized neoplastic B cells with abundant IgM in the cytoplasm as detected by immunohistochemistry. A diagnosis of stage II MALT lymphoma was made, but the patient did not receive therapeutic intervention. As previously reported, Dutcher bodies are mainly observed in B-cell neoplasms with IgM production. Because these characteristic intranuclear inclusions can be easily observed by PAS staining, the presence of PAS reaction-positive Dutcher bodies in FNA cytology can serve as a clue to differentially diagnose MALT lymphoma from plasmacytoma.

Patients with rheumatoid arthritis often develop methotrexate-associated lymphoproliferative disorders (MTX-LPD) during MTX treatment. MTX-LPD occasionally regresses spontaneously after simply discontinuing MTX treatment. In patients without spontaneous regression, additional chemotherapy is required to avoid disease progression. However, the differences between spontaneous and non-spontaneous regression have yet to be elucidated. To clarify the factors important for spontaneous regression, we analyzed the clinicopathological features of 51 patients with rheumatoid arthritis who developed MTX-LPD (diffuse large B-cell lymphoma [DLBCL]-type [n = 34] and classical Hodgkin lymphoma [CHL]-type [n = 17]). We examined the interval from MTX discontinuation to the administration of additional chemotherapy. The majority of DLBCL-type MTX-LPD patients (81%) exhibited remission with MTX discontinuation alone. In contrast, the majority of CHL-type MTX-LPD patients (76%) required additional chemotherapy. This difference was statistically significant (P = 0.001). However, overall survival was not significantly different between DLBCL-type and CHL-type (91% vs 94%, respectively; P > 0.05). Thus, the morphological differences in the pathological findings of MTX-LPD may be a factor for spontaneous or non-spontaneous regression after discontinuation of MTX.

Diffuse large B-cell lymphoma (DLBCL) is the most common B-cell lymphoma subtype, and the Epstein-Barr virus (EBV)-positive subtype of DLBCL is known to show a more aggressive clinical behavior than the EBV-negative one. BTB and CNC homology 2 (BACH2) has been highlighted as a tumor suppressor in hematopoietic malignancies; however, the role of BACH2 in EBV-positive DLBCL is unclear. In the present study, BACH2 expression and its significance were studied in 23 EBV-positive and 43 EBV-negative patient samples. Immunohistochemistry revealed BACH2 downregulation in EBV-positive cases (P < 0.0001), although biallelic deletion of BACH2 was not detected by FISH. Next, we analyzed the contribution of BACH2 negativity to aggressiveness in EBV-positive B-cell lymphomas using FL-18 (EBV-negative) and FL-18-EB cells (FL-18 sister cell line, EBV-positive). In BACH2-transfected FL-18-EB cells, downregulation of phosphorylated transforming growth factor--activated kinase 1 (pTAK1) and suppression in p65 nuclear fractions were observed by Western blot analysis contrary to non-transfected FL-18-EB cells. In patient samples, pTAK1 expression and significant nuclear p65, p50, and p52 localization were detected immunohistochemically in BACH2-negative DLBCL (P < 0.0001, P = 0.006, and P = 0.001, respectively), suggesting that BACH2 downregulation contributes to constitutive activation of the nuclear factor-B pathway through TAK1 phosphorylation in BACH2-negative DLBCL (most EBV-positive cases). Although further molecular and pathological studies are warranted to clarify the detailed mechanisms, downregulation of BACH2 may contribute to constitutive activation of the nuclear factor-B pathway through TAK1 activation.

Objective: Although glucocorticoids are effective for patients with IgG4-related disease, the treatment has not yet been standardized. Therefore, the treatment strategy should be established.
Patients and methods: Patients who fulfilled the comprehensive diagnostic criteria for definite IgG4-related disease were started on prednisolone (0.6mg/ kg body weight) with the dose reduced every two weeks. The subsequent maintenance dose and need for prednisolone were determined for individual patients. The primary endpoint was the complete remission (CR) rate at one year. Secondary end-points included overall response rate (ORR), the maintenance dose, the relapse rate, and adverse events.
Results: This study enrolled 61 patients. After clinicopathological review, three patients were excluded, and one, 13, and 44 patients were diagnosed with probable, possible, and definite IgG4-related disease, respectively. Of the 44 patients with definite IgG4-RD, 29 (65.9%) achieved CR, and the ORR was 93.2%. No patient was refractory to primary treatment. The most frequent adverse events were glucose intolerance. Six patients relapsed.
Conclusions: Glucocorticoid treatment is usually effective for patients with IgG4-RD, and we should examine the possibility of other disorders when a patient is glucocorticoid refractory. Some patients are misdiagnosed, making central clinicopathological review of diagnosis very important in conducting clinical studies.

Mantle cell lymphoma (MCL) is an aggressive B-cell lymphoma characterized by overexpression of cyclin Dl resulting from t(11;14)(q13;q32) translocation. Herein, we report 3 cases of MCL with features of plasma cell type Castleman disease (CD). The 3 patients were all men, ranging from 51 to 74 years in age, and they all presented with systemic lymphadenopathy with anemia, hypoalbuminemia, elevated serum levels of C-reactive protein, and polyclonal hypergammaglobulinemia. Lymph node biopsy specimens of the 3 cases showed histological features of plasma cell-type CD, including atrophic germinal centers and interfollicular plasmacytosis, with no light chain restriction. However, flow cytometric analysis demonstrated an abnormal B-cell population with CD5 expression, and further analysis using cyclin Dl immunostaining highlighted a neoplastic component that was restricted to the mantle zone. These neoplastic cells were immunohistochemically positive for CD20, CD5, and SOX11, and negative for CD3, CD10, and HHV8. The Ki67 index was low. All patients were finally diagnosed with MCL. This rare type of MCL can be misdiagnosed clinically and histologically as CD. Therefore, it is important to recognize this rare type of MCL, and careful examination is required using both histological and flow cytometric analyses.
