Malignant lymphoma can affect the central nervous system (CNS) in three different ways: as a consequence (relapse or invasion) of systemic lymphoma, as a primary CNS lymphoma (PCNSL) without systemic involvement, and through intravascular lymphomatosis (IVL). It is essential to distinguish PCNSL from the others, since the therapeutic strategy for treating this disease differs. FDG-PET/CT fusion imagery is a powerful tool for detecting systemic lesions. If a marked elevation of lactate dehydrogenase and the soluble IL-2 receptor suggests IVL, a random skin biopsy can permit a differential diagnosis. It is not certain why PCNSL occurs solely in the CNS, where there is no lymphatic system. The special environment, so-called "sanctuary site", where is free from attack of the immune system and penetration of chemotherapeutic agents by blood-brain barrier is deeply related to malignant transformation. The prognoses for patients with CNS invasion of systemic lymphoma and those with PCNSL remain bleak in the post-rituximab era. Over half of the patients who received high-dose methotrexate will subsequently relapse. Therefore, novel therapeutic strategies are earnestly sought.

A biomarker for early diagnosis of central nervous system (CNS) lymphoma would permit early treatment for attenuation of disease progression and neurological deterioration. High interleukin-10 (IL-10) or an IL-10/IL-6 ratio >1.0 are informative parameters for discriminating intraocular lymphomas from uveitis. Recent reports have also shown that CSF IL-10 is a potential diagnostic biomarker for CNS lymphoma. The purpose of this study was to evaluate the diagnostic value of IL-10 in cerebrospinal fluid (CSF) in patients with CNS lymphoma compared with other CNS diseases, including CNS tumors and inflammatory diseases. CSF IL-10, IL-6, beta-2 microglobulin, soluble IL-2 receptor and FDG-PET SUVmax were measured in 19 patients with CNS lymphoma (15 primary and 4 secondary diffuse large B-cell lymphomas) and 26 non-lymphoma patients with various brain tumors and inflammatory diseases. The diagnostic accuracy of the respective examinations for differentiation of CNS lymphomas from non-lymphomas was evaluated by receiver operating characteristic (ROC) curve analysis. The area under the ROC curve (AUC) was calculated. CSF IL-10 was detected at significant levels (median, 28 pg/ml; range <2-4,100 pg/ml) in all except one patient with CNS lymphoma, but not detected in any non-lymphoma patients. CSF IL-10 had the highest diagnostic accuracy with AUC = 0.974. At an IL-10 cutoff of 3 pg/ml, the sensitivity and specificity were 94.7 and 100 %, respectively. These results indicate that CSF IL-10 is a superior biomarker for initial screening for patients with CNS lymphoma.

A 60-year-old man complained of nausea, vomiting, decreased appetite, and a feeling of abdominal fullness in August 2013. Based on biopsy findings from an upper gastrointestinal endoscopy examination, a diagnosis of non-Hodgkin's lymphoma (NHL), diffuse large B-cell lymphoma (DLBCL), non-GC type, was made. F18-fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) revealed abnormal accumulations solely in the gastric wall (SUVmax = 14.5), the left adrenal gland (SUVmax = 14.3), and the right adrenal gland (SUVmax = 8.5). The clinical stage (Ann Arbor) was IVA, the serum LDH level was within the reference range, and the International Prognostic Index (IPI) was low-intermediate. The serum soluble IL-2 receptor level was within the reference range, and there was no evidence of HIV, EB virus, or autoimmune disease. After the completion of 4 cycles of R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) and 2 parallel cycles of prophylactic intrathecal (I.T.), an upper gastrointestinal endoscopy and a FDG-PET/CT examination showed complete remission (CR). The patient received 8 cycles of ritsuximab therapy, 6 cycles of CHOP, and 3 cycles of I.T. The patient has maintained a CR for about 14 months. A literature search revealed that malignant lymphoma with involvement confined to the adrenal gland and gastrointestinal tract is exceedingly rare, and only 3 cases of malignant lymphoma have been reported, with involvement of the stomach in 2 cases and the duodenum in 1 case. All of the cases were diagnosed as DLBCL. The case described herein represents the third case with involvement of the stomach.

A 47-year-old woman visited Tokai University Hospital complaining of left cervical lymph node swelling in 2007. The laboratory data were almost normal except for slight anemia (Hgb 10.5 g/dL), elevation of serum soluble interleukin (IL)-2 receptor levels (645 U/mL [normal range 220-530 U/mL]), and positive hepatitis C virus (HCV) antibody. Serum transaminase and lactated dehydrogenase levels were normal. Contrast-enhanced computed tomography (CT) showed lymph node swelling with a diameter of 3 cm at the left supraclavicular fossa and mild splenomegaly, and <sup>18</sup>F-fluorodeoxyglucose positron emission tomography with CT (FDG-PET/CT) revealed abnormal uptake in the left supraclavicular fossa. The patient was diagnosed as having indolent nodal marginal zone B-cell lymphoma by lymph node biopsy. After 9 years with no progression of lymphoma, the patient received 12-week ledipasvir/sofosbuvir therapy for HCV infection and achieved sustained virologic response without any adverse effects. The left supraclavicular mass disappeared in the FDG-PET/CT performed 5 months after antiviral therapy indicating complete response. The serum soluble IL-2 receptor concentration decreased to 244 U/mL. Thereafter, her lymphoma was in remission for 3 years.

A 64-year-old woman was diagnosed with diffuse large B-cell lymphoma (DLBCL) in 2013. After eight courses of R-CHOP therapy followed by local irradiation of the remaining retroperitoneal soft tissue shadow, complete response was confirmed on 18F-2-fluoro-2-deoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT). Early in 2016, patient's serum LDH and soluble IL-2 receptor levels elevated. With suspected recurrence of DLBCL, FDG-PET/CT was performed that showed no lymphadenopathy or abnormal FDG uptake. By the end of July 2016, the patient developed fever and night sweating. Intravascular large B-cell lymphoma (IVLBCL) was suspected, and the patient underwent random skin biopsies, which revealed large atypical cells infiltrating peripheral and intravascular regions of the subcutaneous adipose tissue. Cell morphology, immunostaining, and PCR analysis of the immunoglobulin heavy chain gene suggested the recurrence of DLBCL. Despite salvage chemotherapy and autologous peripheral stem cell transplantation with high-dose chemotherapy, approximately 15 months later, DLBCL recurred and involved the lungs. The patient again received chemotherapy and achieved a second remission. Because DLBCL may recur like intravascular lymphoma, the same tests used for IVLBCL diagnosis are required in cases of suspected recurrence of DLBCL based on clinical and laboratory findings.

There have been only a limited number of reports on primary adult T cell lymphoma/leukemia (ATL) in the bone. This is a case report of a 75-year-old patient initially reporting multiple bone pains that were attributed to osteolytic ATL. The patient developed spontaneous chest/back pain and visited a local hospital. Laboratory tests showed high levels of alkaline phosphatase (ALP), and computed tomography (CT) revealed skeletal lesions with osteolysis. Although multiple myeloma was initially suspected, the results of bone marrow aspiration and bone biopsy were inconsistent. After he was referred to our hospital, mild hypercalcemia (10.4 mg/dL) with low-normal intact parathyroid hormone (PTH) (27 pg/mL), low parathyroid hormone-related protein (PTHrP), and elevated 1,25-dihydroxy vitamin D (1,25OH2D) levels (136 pg/mL) narrowed the differential diagnosis down to lymphomatous and granulomatous diseases, and then, the high serum soluble IL-2 receptor (3,450 U/mL) and the flower cells recognized in the peripheral blood sample suggested the involvement of ATL. Finally, the reevaluation of the iliac bone biopsy sample led us to the histological diagnosis of ATL infiltration in the bone. The subsequent two courses of chemotherapy in addition to denosumab resulted in an objective partial metabolic response indicated in 18-fluorine-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT). Although very rare, the bone involvement of ATL could be used for the differential diagnosis for local osteolytic bone pain in addition to multiple myeloma and metastatic bone diseases.
