Abstract
Background Due to the extreme rarity of pulmonary extranodal natural killer/T-cell lymphoma (ENKTCL), studies on this lymphoma type are limited. We aimed to investigate the clinical presentations, computed tomography (CT) findings, CT dynamic changes, and outcomes of patients diagnosed with pulmonary ENKTCL. Methods We conducted a retrospective cohort study on ENKTCL, nasal type, at West China Hospital, from January 2010 to January 2023. Out of 27 initial cases with pulmonary ENKTCL, we excluded 4 due to the lack of chest CT images, resulting in a final cohort of 23 patients. Our evaluation covered clinical features, laboratory findings, CT presentations, treatment strategies, and survival outcomes. Survival analyses were performed using the Kaplan-Meier method, with log-rank tests for survival curve comparisons. Given the small sample size, our interpretation of the data is mainly descriptive. Results The most common CT presentations in our institution was solitary or multiple nodules (7/23, 30.4%). The halo sign (78.3%) and floating vessels sign (83.3%) were commonly observed in pulmonary ENKTCL. Elevated lactate dehydrogenase (LDH) levels were observed in 20 (86.9%) patients. The median overall survival (OS) for pulmonary ENKTCL patients was 1 month; 3 cases displayed a favorable prognosis, maintaining complete remission (CR) status for 1.5-7 years after receiving chemotherapy. Chemotherapy led to improved prognosis, with a median survival of 5 months seen in patients who received chemotherapy. Patients with bilateral lung involvement had worse outcomes compared to those with unilateral lesions. Conclusions Pulmonary ENKTCL is a rare and aggressive disease, often misdiagnosed due to nonspecific clinical and CT features. Laboratory tests, failure of antibiotic treatment, and "floating vessels sign" on enhanced CT scans may aid in diagnosis. Timely chemotherapy may improve survival, emphasizing the importance of early detection and prompt treatment.

Abstract
Objective: This study aimed at to raise the awareness understanding of primary pulmonary lymphoma (PPL) by analyzing the clinical manifestation, imaging, pathology, diagnosis, treatment, and prognostic features of 50 cases of PPL. Methods: The study of 50 individuals with PPL diagnosed at the First affiliated hospital of Nanchang university between January 2009 and December 2019 was performed. Results: Overall, 27 males and 23 females were enrolled, with an average age of 57.6 ± 15.6 years. The primary symptoms included, cough (n = 37), expectoration (n = 25), sputum with blood (n = 12), and chest pain (n = 12). Two individuals had Hodgkin's lymphoma and 48 patients had non-Hodgkin's lymphoma (NHL). We divided the NHL cases into mucosa-associated lymphoid tissue lymphoma (MALT) (n = 21), diffuse large B-cell lymphoma (n = 12), small lymphocytic lymphoma (n = 2), mantle B-cell lymphoma (n = 2), follicular lymphoma (n = 1), B-cell lymphoma without further classification (n = 8), and T-cell lymphoma (n = 2). The imaging findings revealed that unilateral lung involvement was more common among the patients. The longest follow-up duration up to December 2019 was 123 months with 40 surviving patients. The 5-year overall survival and progression-free survival were 46.7% and 44.4%, respectively. Age was an independent predictive factor for the 5-year survival (hazard ratio, 8.900; P = .038), (P < .05). Conclusion: PPL is a uncommon disease with atypical clinical manifestations and is often misdiagnosed. Immunohistochemistry is currently the standard used in pathologic evaluation of PPL. MALT prognosis is better in contrast with other kinds of PPL. Surgery or radiotherapy can be considered in patients with limited lesions, and chemotherapy is the first treatment option for diffuse lesions. Age of ≥ 60 years was reported as an independent adverse predictive factor.

Abstract
Objective: To explore the clinical characteristics, the best treatment and prognostic factors of primary pulmonary NK/T-cell lymphoma. Methods: A total of 24 cases with primary pulmonary NK/T-cell lymphoma from April 2011 to May 2019 were analyzed retrospectively. Survival analysis was performed using the Kaplan-Meier method and groups were compared using the log-rank test. Multivariate analysis using Cox proportional hazard regression model was conducted to confirm independent prognostic factors for overall survival (OS) and progression-free survival (PFS) . Results: ①The cohort of 24 patients included 16 male and 8 female with a median age of 49 years (range, 4-76 years) old. ②Most patients initially presented with a fever (66.7%) , cough and dyspnea. Chest imaging manifestations were primarily unilateral (45.8%) or bilateral (54.2%) pulmonary consolidation, nodules or mass. ③20 patients received chemotherapy, radiotherapy or hematopoietic stem cell transplantation, the rest 4 cases palliative treatment. Median OS was 9.5 months (range, 0.1-26.0 months) . The estimated 1-year OS rate was 45.8%. Overall response rate of patients treated with asparaginase-based regimen was 88.2%. ④In univariate survival analysis, age≤60 was prognostic for longer OS and PFS, compared with age>60 (P=0.002 and 0.004, respectively) ; ECOG≤2 was prognostic for longer OS and PFS, compared with ECOG>2 (P=0.042 and 0.004, respectively) . In multivariate survival analysis, age>60 and ECOG>2 were significantly correlated with inferior OS and PFS (OS: P=0.024 and 0.024, respectively; PFS: P=0.035 and 0.024, respectively) . Conclusions: Primary pulmonary NK/T-cell lymphoma was a rare disease with poor prognosis. Asparaginase-based regimens appeared to be effective. Age and ECOG served as independent prognostic factors for primary pulmonary NK/T-cell lymphoma patients.

Abstract
Background Pulmonary non-Hodgkin lymphoma (NHL) is rare. The most frequent subtype of pulmonary NHL is low-grade B-cell lymphoma, such as lymphoma of mucosa-associated lymphoma tissue. Extranodal natural killer cell/T-cell lymphoma, nasal type (ENKL) is characterized by predominant extranodal involvement and association with Epstein-Barr virus (EBV). ENKL with massive lung involvement has been infrequently reported, and its prognosis is extremely poor. Case presentation A 20-year-old Japanese man presented with intermittent fever lasting for 2 months. Radiological imaging demonstrated multiple nodules of uneven shape and size in both lungs. Video-assisted thoracic surgical lung biopsy showed abnormal lymphocyte infiltration, which was positive for CD3, CD56, and perforin. In situ hybridization for EBV-encoded RNA was positive. From these findings, he was diagnosed with ENKL with lung involvement. The patient was successfully treated with intensive combinational chemotherapy followed by allogeneic cord blood transplantation. He has been alive with continuous complete remission for 1 year after diagnosis. Conclusions Although ENKL involving the lung has been reported to have dismal outcomes, our patient showed long-term survival after intensive chemotherapy and up-front allogeneic hematopoietic transplantation. The present case highlights the importance of early diagnosis as well as allogeneic transplantation.

Abstract
Extranodal natural killer (NK)/T-cell lymphoma (ENKTL) is an aggressive disease with poor prognosis. The lung is a relatively rare site of involvement. The current study presents a case of primary pulmonary ENKTL with fever and dyspnea, mimicking pneumonia and initially treated with empirical antibiotics. The patient demonstrated rapid deterioration and died shortly following diagnosis. To the best of our knowledge, large-scale investigations referring to primary pulmonary ENKTL are not available. As a result, the exact incidence and clinical features of primary pulmonary ENKTL are unknown. In the current report, a literature review is presented to discuss the clinical characteristics, diagnosis, treatment, and prognosis factors of this malignant disease.

Abstract
Background The primary pulmonary lymphoma (PPL), with a low incidence, was highly misdiagnosed in clinic. The present study analyzes the clinical features, laboratory and imaging data, pathologic characteristics, and summarizes misdiagnosis reasons of PPL cases, aims to provide a better understanding and increase the accuracy of early diagnosis and minimize the misdiagnosis of PPL. Methods The clinical data of 19 cases were collected from the first affiliated hospital of Wenzhou medical university (PRC) from April 2010 to May 2016. All cases were confirmed by pathology. The process of misdiagnosis was described. This study retrospectively analyzed the incidence, clinical presentation, laboratory examination, Chest CT scan and diagnosis of the cases. Results The symptoms of the 19 cases were dyspnea, fever, hemoptysis, chest pain or physical findings without obvious symptoms. Five patients were pneumonia-like, nine patients had lung single nodule or mass and four patients got pleural effusion, which were reported by computed tomography (HRCT) scan. There were 2 cases of Hodgkin lymphoma (HL), and 17 cases of non-Hodgkin lymphoma (NHL). In NHL cases, 12 cases were confirmed mucosa associated lymphoid tissue B lymphoma type, 3 cases were confirmed diffuse large B-cell lymphoma, angioimmunoblastic T-cell lymphoma and ALK positive anaplastic large cell lymphoma were one case separately. Clinical and imaging manifestation of PPL is untypical, but there are still some hints: 1) Fuzzy shadow at the edge of lung mass with air bronchogram; 2) Lung mass shadow stable for a long time; 3) Pneumonia-like changing without infections clinical and lab manifestation. Thirteen patients (68.4%) were misdiagnosed as pneumonia, lung cancer and tuberculosis initially. The term between initial diagnosis and final diagnosis lasted for half a month up to 2 years, with median time of 6 months. Two cases were misdiagnosed as tuberculosis. One case was misdiagnosed as small cell lung cancer. Conclusion Clinical and imaging manifestation of PPL is untypical. Biopsies should be taken actively if the imaging findings don’t match the symptoms or the anti-infection treatments to “lung infection” don’t work. Accurate diagnosis requires adequate tissue sampling with appropriate ancillary pathologic studies. If clinical manifestation and the diagnosis don’t match, repeated biopsy should be ordered.

Abstract
Extranodal natural killer (NK)/T cell lymphoma, nasal type is a condition that has poor prognosis. Accurate diagnosis of lymphoma is made by pathological findings. We report a case of extranodal NK/T cell lymphoma, nasal type affecting the lung and liver and which was difficult to diagnose because of negative biopsy results from multiple sites. A 39-year-old man who had dry cough and fever for 1 month was referred to our hospital. He had pancytopenia and elevated serum levels of lactate dehydrogenase and soluble interleukin-2 receptor. Hepatosplenomegaly and multiple lung nodules were found on imaging study. Specimens of bronchoscopic lung, percutaneous liver, bone marrow and random skin biopsies were all negative. Open lung biopsy was not definitive. Unfortunately, disease progression was rapid and fatal before results of pleural fluid cytology and a second liver biopsy showed extranodal NK/T cell lymphoma, nasal type. This report focused on diagnostic planning for rapidly progressive extranodal NK/T-cell lymphoma, nasal type.
