Objectives : The aim of this study was to report the improvement of fever, myalgia, performance status, and headache after treatment with Osuyubujaijung-tang and Geopoong-san in a Soeumin with Peripheral T-cell lymphoma. Methods : We retrospectively reviewed the medical records, medical laboratory and image scans of 80-year-old male patient diagnosed as peripheral T-cell lymphoma. He couldn't conduct any conventional chemotherapy due to poor performance status, ECOG 4. Results : The symptoms of myalgia, poor performance status, and neck pain improved, and fever was reduced with Osuyubujaijung-tang. Headache was subsided with Geopoong-san. Conclusions : A patient with peripheral T-cell lymphoma suffering from fever, myalgia, poor performance status, neck pain and headache showed the improvement of symptoms with treatment of Osuyubujaijung-tang and Geopoong-san. After 4 months treatment, the patient could conduct self care, physical activity and social affairs.

Natural Killer/T-cell(NK/TC) lymphoma is a rare disease of oral and maxillofacial region with an aggressive clinical course, showed unusual clinical manifestations. Prognosis is generally poor and the disease is invariably fatal after systemic dissemination. A case of nasal NK/TC non-Hodgkin's lymphoma in the left maxilla that showed unusual clinical manifestations and a fulminant course of disease, are described with literature reviews. A 81-year-old female patient presented with rapidly growing ulceration and general malaise after extraction of right upper second premolar NK/TC lymphoma was subsequently detected by biopsy. rapid and wide invasion from maxilla to mandible developed within 10 days and multiple metastasis to whole body was after a few weeks. Although the time relationship is not clear, local invasion and multiple metastasis could be dissemination from localized disease of NK/TC. As seen in my case, the course can be excessively aggressive and fulminant even though it first appeared as a localized ulceractive lesion. She is expired 2 months after biopsy. Positivity of immunohistochemical stain (CD56, LCA, UCHL-1, CD3), which is a specific characteristic of NK/TC, may serve as a factor showing a poor prognosis of a malignant lymphoma

A two-year-old spayed female Persian cat demonstrated weight loss, anorexia, and vomiting for one week. Hematologic findings suggested chronic renal failure. Radiography and ultrasonography revealed severe bilateral renomegaly with hypoechoic nodules and subcapsular hypoechoic rim. Fine needle aspiration of the kidney revealed malignant lymphoma. The cat received in-hospital treatment for chronic renal failure for seven days, followed by chemotherapy (cyclophosphamide, vincristine, and prednisolone). The cat tolerated chemotherapy well and chronic kidney disease was alleviated. However, complete remission was not achieved. After 93 days of treatment, the cat exhibited anisocoria and mental dullness. Brain magnetic resonance imaging revealed hypertrophy and enhancement of cranial nerves. Chemotherapy was replaced with lomustine (10 mg orally), and two weeks later, cytosine arabinoside (50 mg/㎡ subcutaneously), twice daily for consecutive days. Five days after substitution chemotherapy, the patient showed anemia due to severe intestinal bleeding and died. Post-mortem examination and histopathologic analysis confirmed renal T-cell lymphoma with metastasis to the central nervous system, colon, and nasal cavity. Survival time was 117 days after the diagnosis of renal lymphoma.

Canine T-zone lymphoma (TZL) is a mature T-cell lymphoma in dogs. The diagnosis and sub-classification are impossible without biopsy or immunophenotyping by flow cytometry. An 11-year-old, spayed, female Golden Retriever presented with lymph node enlargement. Clinical examination was consistent with canine multicentric lymphoma. However, immunophenotyping revealed positive for CD3, CD4, CD5, CD8, CD21, TCRαβ, and MHCII but negative for CD34, CD45, CD79a, and TCRγδ. Histopathology revealed lymphocytes expanding to the cortex-preserving architecture and thinning of the nodal capsule, and CD3 positive but PAX-5 negative. Owing to the indolent nature of TZL, careful monitoring approach without clinical intervention was utilized.

Breast implant-associated anaplastic large-cell lymphoma (BIA-ALCL) is a rare T-cell non-Hodgkin lymphoma characterized as CD30 positive and anaplastic lymphoma kinase (ALK) negative. In 2016, the World Health Organization declared BIA-ALCL as a new disease entity. The first case of BIA-ALCL was reported in 1997, and as of July 2019, the United States Food and Drug Administration had cited a total of 573 United States and global medical device reports of BIA-ALCL, including 33 deaths. In all clinical case reports, except for those with unknown clinical history, the patient had received at least one textured surface breast implant. Although the etiology is not yet clear, chronic inflammation has been proposed as a potential precursor to tumorigenesis. The most common presentation of BIA-ALCL is peri-implant fluid collection following aesthetic or reconstructive implantation with textured surface breast implants. It can be accompanied by breast swelling, asymmetry, pain, skin lesions, lymphadenopathy, and B-type symptoms. Most cases are detected on average 7 to 10 years after implantation. Diagnostic specimens can be obtained with fine-needle aspiration or biopsy. BIA-ALCL is CD30 positive, epithelial membrane antigen positive, and ALK negative. It can be cured with complete surgical excision at the T1-T3 stage.

Primary central nervous system lymphoma is a rare form of extranodal non-Hodgkin lymphoma, and primary T-cell lymphoma of the cauda equina is extremely rare. We describe a case involving a 56-year-old female who presented with low back pain and radiating leg pain for 4 months. MRI of the lumbar spine revealed an elongated, multinodular intradural lesion of approximately 10 cm from the L4 body to the S2 body level with iso-signal intensity on T1-weighted imaging, heterogeneous iso- and high-signal intensity on T2-weighted imaging, and a heterogeneous intense enhancement on gadolinium contrast-enhanced T1-weighted imaging. A peripheral T-cell lymphoma of the cauda equina was diagnosed on the basis of immunohistochemical and T-cell receptor gamma gene rearrangement analysis after intradural biopsy of the mass.

Angioimmunoblastic T-cell lymphoma (AITL) is a lymphoproliferative disorder of mature T follicular helper cells. Atypical lymphoid cells were observed in the bone marrow of an 80-year-old woman, and the flow cytometric determined immunophenotypes of B-cells were unusual, that is, CD19+, CD20-, and CD22- with lambda light chain restriction. Initially, we suspected BM involvement of B-cell lymphoma based on the presence of abnormal B-cells. However, the patient was diagnosed with AITL involving BM. A re-analysis of flow cytometric immunophenotyping revealed a minor, aberrant T-cell population, and the lambda light chain restriction observed by surface staining was considered non-specific binding. This case demonstrates B-cells in patients with EBV-positive T-cell lymphoma may exhibit immunophenotypes resembling those of plasma cells, and that proliferation of abnormal B-cells or plasma cells could also potentially mask underlying T-cell lymphoma. A more integrated approach is required for accurate diagnosis.

Metformin is a treatment used widely for non-insulin-dependent diabetes mellitus with few side effects and acts by inhibiting hepatic gluconeogenesis and glucose absorption from the gastrointestinal tract. Lymphoma is one of the most common hematological malignancies in dogs. Chemotherapy is used mainly on lymphoma, but further research on developing anticancer drugs for lymphoma is needed because of its severe side effects. This study examined the anticancer effects of metformin alone and in combination with 2-deoxy-D-glucose (2-DG), a glucose analog, on EL4 cells (mouse T cell lymphoma). Metformin reduced the metabolic activity of EL4 cells and showed an additive effect when combined with 2-DG. In addition, cell death was confirmed using a trypan blue exclusion test, Hochest 33342/propidium iodide (PI) staining, and Annexin V/PI staining. An analysis of the cell cycle and mitochondria membrane potential (MMP) to investigate the mechanism of action showed that metformin stopped the G2/M phase of EL4 cells, and metformin + 2-DG decreased MMP. Metformin exhibited anticancer effects as a G2/M phase arrest mechanism in EL4 cells and showed additive effects when combined with 2-DG via MMP reduction. Unlike cytotoxic chemotherapeutic anticancer drugs, metformin and 2-DG are related to cellular glucose metabolism and have little toxicity. Therefore, metformin and 2-DG can be an alternative to reduce the toxicity caused by chemotherapeutic anticancer drugs. Nevertheless, research is needed to verify the in vivo efficacy of metformin and 2-DG before they can be used in lymphoma treatments.

The radiologically detectable pulmonary involvement of NHL at diagnosis is about 4%. The commonest intrathoracic manifestations of secondary pulmonary lymphoma are mediastinal or hilar lymph node enlargement And the most frequent manifestations of pulmonary parenchymal lymphoma are lymphomatous nodules. But, when patients with newly diagnosed lymphoma exhibit rapidly progressive parenchymal lesions, an infection, such as pneumonia, is usually suspected. We present a report of a patient who developed rapidly progressive pulmonary involvement with T cell lymphoma, which was considered to be pneumonia because of high fever and rapidly progressive radiologic findings.

Objective: To investigate the effect of epirubicin on soluble CD25 (sCD25) secretion by CD4+CD25+ regulatory T (Treg) cells isolated from diffuse large B-cell lymphoma (DLBCL) patients. Methods: Treg cells were isolated from the peripheral blood mononuclear cells isolated from the newly diagnosed DBLCL patients. The concentration of sCD25 in the supernatant was determined with a commercial sCD25 (IL-2R) enzyme-linked immunosorbent assay (ELISA) kit. The fluorescence intensity of CD25 was detected by flow cytometry. Results: Cell survival rate was significantly decreased along with the increase of epirubicin concentration after treatment for 24 h. There was also a significant difference in the concentration of sCD25 between the epirubicin group and the control group (P<0.01). A positive correlation between the Treg cells survival rate and the concentration of sCD25 was detected (r=0.993, P<0.01). When equal numbers of CD4+CD25+ Treg cells of the epirubicin group and the control group were cultured for another 24 h without epirubicin the CD25 fluorescence intensity on the surface of Treg cells was obviously higher in the epirubicin group than that in the control group (P<0.01), while the sCD25 concentration in the supernatant in the epirubicin group was significantly lower than that in the control group (P<0.05). Conclusion: Epirubicin may improve the body's immune functions by inhibiting the sCD25 secretion by Treg cells in DLBCL patients.
