Abstract
Primary central nervous system (PCNS) extranodal NK/T-cell lymphoma, nasal type (ENKTCL), is an exceedingly rare tumor. To the best of our knowledge, only 27 cases and only one reported aberrant CD20 expression have been documented in the literature. Here we present a second case of PCNS ENKTCL with aberrant CD20 expression in a 43-year-old immunocompetent Chinese female. The patient presented with tremors, weakness in the right upper limb, and a slow reaction. Magnetic resonance imaging revealed multiple brain lesions. A histological examination revealed a diffuse distribution of intermediate-sized pleomorphic lymphocytes with angiocentric growth. The tumor cells expressed CD2, CD3, CD56, T-cell intracellular antigen-1, granzyme B, and Epstein-Barr virus-encoded RNAs (EBERs), with additional partial and weak CD20 and CD30 expression. Despite a confirmatory pathological diagnosis, the patient refused treatment and was discharged, ultimately dying from the disease. In the literature review, the clinical, immunohistochemical, EBERs, treatment, and prognostic features of PCNS ENKTCL were summarized. Although PCNS ENKTCT is extremely rare, it does occur and should always be included in differential diagnoses. CD20 expression should be evaluated routinely with relevant markers. The accumulation of cases is crucial for developing an effective treatment strategy for this rare and aggressive malignancy.

Abstract
Primary central nervous system extranodal natural killer/T-cell lymphoma (PCNS ENK/TCL) is an extremely rare lymphoma. Only 23 cases of PCNS ENK/TCL have been reported in the English literature. Due to the rarity of this lymphoma, an effective therapeutic strategy has not been defined. Generally, this type of lymphoma is treated with surgery, intrathecal chemotherapy, and postoperative chemoradiation therapy. The prognosis is poor. Herein, we present a case of primary brain NK/T cell lymphoma in a 50-year-old immunocompetent Chinese female and review the literature. The patient underwent intracranial tumor resection and was subsequently treated with a PD1 monoclonal antibody (Sintilimab) combined with chemotherapy. The patient survived 15 months after diagnosis. This is the first report of PCNS ENK/TCL treated with surgery and chemotherapy combined with immunotherapy and suggests an effective treatment regimen for PCNS ENK/TCL.

Abstract
RATIONALE Intraocular infection of Epstein-Barr virus (EBV) may cause severe visual loss. However, it is relatively rare, and there is no consensus on its treatment. PATIENT CONCERNS A 44-year-old woman complained of a right-eye floater and exhibited a unilateral exudative change along the retinal veins at the Department of Ophthalmology, St. Luke's International Hospital. DIAGNOSIS EBV retinitis was diagnosed based on EBV-positive (9.09 × 103 copies/μl) and cytomegalovirus-negative results in the aqueous humor. INTERVENTIONS Oral prescription of valaciclovir hydrochloride, and an intravitreal injection of foscarnet sodium hydrate was administered. However, the retinal infiltration progressed, and vitreous opacity with cellular infiltration appeared. Intravitreal methotrexate (MTX) injection effectively suppressed retinal and vitreous infiltration. However, she developed optic-nerve papillitis, and central retinal vein occlusion related to the severe swelling of the optic-nerve, and began steroid pulse therapy. Considering the increase in intraocular EBV levels to 6.4 × 104 copies/ml, we restarted intravitreal foscarnet injections replacing MTX. This in turn rapidly reduced the EBV levels to 3.27 × 104 copies/ml, followed by papillitis alleviation. OUTCOMES The intraocular MTX administration reduced the inflammatory vitreous and retinal infiltration, but not the EBV load, while foscarnet reduced the EBV load and papillitis, but not vitreous infiltration. LESSONS The retinal infiltration may have involved EBV infection to the retinal neurons but also EBV-free reactive inflammatory cells. EBV infection to the neurons may have been, at least partially, treated by intravitreal foscarnet treatment, and the reactive inflammatory cells by intravitreal MTX. Further observations are warranted to reach a consensus on treating intraocular EBV infection.

Abstract
The aim of this study is to describe the involvement of Epstein-Barr Virus (EBV) in the diseases of the ocular anterior segment. This is a narrative review designed using the PUBMED, SCOPE and Web of Science databases, searching for reported literature on findings in the anterior ocular segment related to EBV between 1990 and 2020. Epstein-Barr Virus (EBV) is implicated in the development of salmon-coloured conjunctival masses in the context of acute mononucleosis and lymphoproliferative disorders. Moreover, EBV can cause haemorrhagic conjunctivitis and its corneal implications appear as different types of keratitis patterns. The involvement of EBV in the pathogenesis of anterior segment inflammation is not well-defined. Current evidence regarding anterior segment disease caused by EBV infection has been proved by positive viral detection through polymerase chain reaction test in eyes with lymphoproliferative disorders known to be caused by EBV, as B- and NK/T-cell lymphoid tumours. Antiviral treatment (oral Aciclovir or Valaciclovir) in anterior segment disease caused by EBV remains controversial.

Abstract
Purpose Herein, we report a case of primary intraocular lymphoma (PIOL) with the first presentation of bilateral Epstein-Barr virus- (EBV-) associated panuveitis. Case Presentation. A 69-year-old male was referred with a three-day history of blurred vision and pain and redness in his left eye following cataract surgery. Examination revealed panuveitis, vitritis, and necrotizing retinitis with retinal hemorrhage. A month later, the right eye was also involved. Polymerase chain reaction-based analysis of the vitreous sample was positive for EBV, and cytological evaluation was compatible with the diagnosis of B-cell lymphoma. A significant improvement was observed following serial intravitreal rituximab and methotrexate injections. The central nervous system and lungs were involved after 6 months, and the patient expired despite systemic chemotherapy. Conclusion There may be an association between EBV panuveitis and primary intraocular B-cell lymphoma.

Abstract
BACKGROUND Extranodal NK/T-cell lymphoma (ENKTCL), nasal type is a very rare and aggressive non-Hodgkin lymphoma. Most commonly it occurs in the upper aerodigestive tract. But, it can also manifest at locations such as the skin, soft tissue, gastrointestinal tract (GI), lungs, testis, etc. These locations are designated as extranasal ENKTCL. The patients with the latter have often more adverse clinical features and poorer survival rate compared with nasal sites. We present a case of an 83-year-old patient with a primary ENKTCL, nasal type, with extranasal presentation in the right upper eyelid. MATERIAL AND METHODS Materials for the literature review was obtained by a comprehensive search on PubMed, which yielded 82 eligible cases with extranasal ENKTCL. RESULTS Sixty-eight cases (83 %) were localized as primary ENKTCL in the lungs (17), central nervous system (CNS) (14), testis (11), GI-tract (7), skin (6), orbit and intraocular tissue (4), pancreas (2), adrenal gland (2), breast (1), etc. 14 cases (17 %) presented as extended or disseminated diseases involving exclusively organs outside the upper aerodigestive tract. There was no systematic pattern of organ involvement in the extended/disseminated ENKTCL. 63 % of the patient with localized extranasal ENKTCL and about 50% of patients with extended/disseminated disease were reported to have died of the disease. Treatment strategies varied with no preferred option. Among the used treatment options were chemotherapy, radiotherapy, surgery, stem cell transplantation alone or in different combinations. CONCLUSION ENKTCL is a highly aggressive disease which may present in extranasal areas. Although the tumors respond to both chemotherapy and radiotherapy, durable complete remissions are very rare.

Abstract
PURPOSE To present a case of necrotizing retinitis with Epstein-Barr virus (EBV)-positive ocular fluid in a patient with sudden unilateral vision loss, which was successfully treated with intravitreal methotrexate (MTX) injections. METHODS Retrospective case report. RESULTS An 83-year-old female who had been on methylprednisolone for 20 years due to interstitial pneumonia developed vitreous opacity and extensive necrotizing retinitis with retinal hemorrhage sparing the posterior pole in the left eye. Multiplex polymerase chain reaction (PCR) for viral DNA using vitreous sample was positive for EBV but negative for herpes simplex virus, varicella-zoster virus, and cytomegalovirus. Real-time PCR detected EBV-DNA in aqueous humor but not in peripheral blood sample. Serologic testing was negative for Toxoplasma gondii, syphilis, and HIV. The patient did not respond to systemic ganciclovir or acyclovir. Subsequent treatment with intravitreal MTX resulted in immediate clinical improvement correlating with a decrease in copy number of EBV-DNA. CONCLUSION Intravitreal MTX may be an effective treatment option for patients with necrotizing retinitis and EBV-positive ocular fluid not responding to conventional antiviral therapy.

Abstract
RATIONALE Extranodal natural killer T-cell lymphoma nasal type (ENKL) is an extremely rare tumor with a very low survival rate. In recent decades, only a few ENKL cases have been published. Presenting a special ENKL case lead the authors to emphasize the primary features of ENKL in early diagnosis and therapy. Here we report an unusual ENKL case which was initially found in the eyes and presented as masqueraded uveitis PATIENT CONCERNS:: A 55 years old female, with vision loss in the right eye for approximately 6 months, and vision blurry, redness and pain in the left eye for 2 weeks, was referred to our hospital. DIAGNOSIS Clinical examinations and images demonstrated bilateral anterior uveitis, retinal and choroidal detachment, and secondary glaucoma. After 3 months, the patient began to present a sore throat, fever, and headaches. The computed tomography (CT) and magnetic resonance imaging (MRI) of her skull demonstrated nothing positive. One month later, a neoplasm was found in her nasopharynx and tonsil, which was confirmed, by histopathology, as ENKL INTERVENTIONS:: This patient was prescribed with steroid for 3 months because of the first diagnosis by the ophthalmologist. After the other symptoms like a sore throat, fever and headaches occurred, symptomatic treatment was given. Unfortunately, when the real cause was found, the patient could not tolerate the other treatment for ENKL. OUTCOMES Since the patient was treated with steroid without improvement, she died due to the septic shock and multiple organ failure. LESSONS Clinicians should always be cautious to ENKL which can be easily be misdiagnosed in the early stage. Early diagnosis and appropriate treatment are keys to raise the survival rate of ENKL patients.

Abstract
Non-Hodgkin's Lymphoma (NHL) is a group of lymphoid malignancies with unsatisfactory treatment effect in some aggressive subtypes, including diffuse large B cell lymphoma (DLBCL). Emodin is an anthraquinone with potent anti-cancer activities. However, the molecular mechanism of Emodin repressing aggressive NHL remains to be revealed in detail. This study delineated the active mechanism of Emodin action in aggressive NHL by using bioinformatics analysis and in vitro assay. 4 Emodin's primary direct protein targets (DPT) were identified and the DPTs-associated proteins/genes were predicted. Those Emodin-related proteins/genes were subject to enrich Emodin-associated pathways, from which 3 significantly NHL-related signal pathways were refined identified. Advanced integrated analysis exhibited TP53 and PI3K as the significant molecule and pathway by which Emodin may function in NHL. To verify those bioinformatics findings, effects of Emodin and E35, a novel derivative of emodin were investigated on DLBCL cell lines SU-DHL4. Emodin and E35 suppressed proliferation and induced apoptosis of SU-DHL4 cells in a time- and dose-dependent manner. Emodin and E35 declined TP53 protein expression and decreased phosphorylation of PI3K/AKT protein in a dose-dependent manner. All of above showed that combined bioinformatics analysis with experiments offered a novel approach for outlining the mechanisms of Emodin action in DLBCL with convenience and integrity.
