From 1987 to 1993, 12 cases of primary gastric malignant lymphoma (PGML) were hospitalized. The incidence of PGML was 1.9% of gastric malignancies during the same period. There were 5 cases in stage Ⅰ, 4 in stage Ⅱ, 1 in stage Ⅲ, and 2 in stage Ⅳ. The preoperative diagnosis of PGML was difficult because the incidence of PGML is low, the symptoms are nonspecific, and the radiologic and fibrogastroscopic character were very similar to those of gastric carcinoma and peptic ulcer disease. The surgical treatment of PGML is disccused.
ObjectiveTo investigate the clinical, ophthalmological and pathological features of primary uveal lymphoma.MethodsRetrospective clinical study. From 2012 to 2018 in Beijing Tongren Eye Cener, 4 cases and 4 eyes of patients with primary uveal lymphoma were included in the study. Among them, 3 cases were male and 1 case was female. The average age was (54 ± 13.58) years old. The average time from initial diagnosis to pathological diagnosis was (18.50 ± 9.29) months. 3 cases were enucleated and 1 case was biopsied. Extranodal marginal zone lymphoma (EMZL) of the mucosa associated lymphoid tissue (MALT) was confirmed by pathological examination. BCVA, fundus color photography, color Doppler ultrasound and orbital MRI were performed in all eyes. UBM, OCT, FFA and ICGA were performed in 2 eyes, 3 eyes, 3 eyes and 2 eyes respectively. The clinical, imaging and pathological changes were observed. Following up time was ≥ 6 months.ResultsAt the initial diagnosis, BCVA was 0.6, 0.02 and 0.01 in 1, 2 and 1 eye respectively. Choroid, ciliary body and iris were involved in 3 eyes, choroid in 1 eye. The fundus of the eyes showed infiltration of choroid in yellow and white color, and the lesions were beyond the vascular arch to the equator and peripheral areas. Color Doppler ultrasonography showed that choroidal diffuse thickening and extrascleral extension (ESE) which was the corresponding hypoechoic areas behind the sclera. Among them, ESE showed crescent thickening in 1 eye and nodular thickening in 3 eyes. UBM showed that the echo of ciliary body was thicken and the internal echo was decreased with the iris involved. OCT showed that RPE was wavy and local retinal neuroepithelial layer detached. FFA showed that the early lesions were mottled with strong and weak fluorescence, and the late fluorescence leakage. The posterior wall of the eyeball was thickened and enhanced in MRI.ConclusionThe clinical manifestations of uveal lymphoma are various, color Doppler ultrasound has characteristic manifestations and ESE of crescent or nodular thickening is valuable in diagnosis.
ObjectiveTo improve the knowledge of primary tracheobronchial lymphoma.MethodsTwo patients with primary tracheobronchial lymphoma admitted to First Affiliated Hospital Guangxi Medical University in 2013 and in 2016 were analyzed retrospectively, and related literatures were reviewed. Chinese National Knowledge Infrastructure, Wanfang database and VIP database were searched by using " trachea lymphoma” or " bronchus lymphoma” as keywords. Meanwhile, databases including PubMed, Ovid Medline and Embase database were retrieved with " Trachea” or " Bronchus” AND " Lymphoma” as keywords. Seventy-two cases of primary tracheobronchial lymphoma were reported, the clinical feature, imaging feature, pathological feature, treatment and prognosis of 72 cases were analyzed.ResultsThe two patients were both females. The chief complaints included cough and dyspnea. The tissue biopsy under bronchoscope was the main diagnostic method. On histopathology, one case was diagnosed grade B cell lymphoma, another was diagnosed mantle cell lymphomas. After chemotherapy, the symptoms were relieved and never relapsed in the follow-up period until October 2016. Literature review found 72 patients with primary tracheobronchial lymphoma with women being the majority (47 cases, 65.28%). The patients aged from16 to 82 years with a median age of 51 years, and nine cases (12.5%) of the patients aged from 16 to 30 years. The specific clinical symptoms were cough and dyspnea. Pulmonary function prompted obstructive dysfunction of pulmonary ventilation. The chest CT scan showed consolidation shadow in trachea and bronchus with or without pulmonary atelectasis. Neoplasms could be found by bronchoscopy. Mucosa-associated lymphoid tissue (MALT) lymphoma was the most common pathological characteristic (36.11%). Mantle cell lymphomas has not been reported currently.ConclusionsPrimary tracheobronchial lymphoma is one of the rare airway tumors. Its clinical features, imaging examinations and bronchoscopic characteristics are not specific, which can be easily confused with lung cancer. It also can cause life-threatening airway obstruction. The bronchoscopy play an important role in diagnosis of primary tracheobronchial lymphoma, while the diagnosis is confirmed by histopathological examination. The main pathology type is MALT lymphoma. The prognosis is good.
Objective To explore the clinical characteristics, diagnose and treatment of bronchiolitis obliterans (BO) associated with lymphoma and paraneoplastic pemphigus (PNP). Methods One patient with BO associated with lymphoma and paraneoplastic pemphigus was presented and literatures which searched through Wanfang Med online and PubMed on this subject were reviewed. Results A 44-year-old woman was admitted to this hospital because of oral ulcer for two years, and persistent dyspnea for fourteen months. She had been diagnosed with PNP one year earlier. Pulmonary function displayed severe obstructive ventilator dysfunction, negative response to the bronchodilator. Chest CT showed bronchiolectasis. The ratio of neutrophils increased in bronchoalveolar lavage fluid. The pathology of ultrasound-guided neck and inguinal lymph node biopsy showed non-Hodgkin’s lymphoma. Based on the clinical presentation, the image and pathology of this patient, the diagnosis of having PNP with BO secondary to the lymphoma was made. After 10 cycles of CHOP chemotherapy, lymphoma and PNP went into remission, but the patient died from respiratory failure. The literatures were reviewed and 15 patients were found, out of them 60% (9/15) were female, 47% (7/15) follicular lymphoma and 47% (7/15) diagnosis of clinical BO which did not be supported by pathology. Lymphoma-PNP-BO was a clinical syndrome and 67% of the initial presentations were PNP. Patients died within 7 to 60 months. Conclusions BO associated with lymphoma and PNP is rare and the most common initial presentation is PNP. BO is the major cause of death. Treatments included chemotherapy, corticosteroid and immunosuppressor, lymphoma and PNP can be alleviated, but BO is aggravating.
Primary vitreoretinal lymphoma (PVRL) is one of the most common type of primary intraocular lymphoma. The current treatment options include local ocular radiotherapy (radiotherapy), systemic chemotherapy (chemotherapy), local ocular chemotherapy, and combination therapy. The treatment options are different at different stages of PVRL, however, there is no uniform treatment guideline. Local ocular chemotherapy can make the drug reach effective therapeutic concentration in the eye, and it can be repeated many times. At the same time, it can avoid the adverse reactions caused by systemic medication or radiotherapy. It is an ideal choice for relieving ocular symptoms. At present, the mainstream ocular local chemotherapeutics are methotrexate (MTX) and rituximab (RTX). The basic consensus about the intravitreal injection of MTX (IVM) is the induction-consolidation-maintenance model, however, the time of each stage and frequency of IVM are diverse. The time interval of intravitreal injection of RTX is also variable, ranging from 1 time/week to 1 time/months and so on. Corneal epithelial lesions caused by frequent MTX injections and the higher recurrence rate after RTX treatment are the main reasons for changing the treatment plan. For patients with primary central nervous system lymphoma and PVRL, combined treatment with neurology department is necessary to save patient's lives, ophthalmology treatment relieves ocular symptoms and improves the patient's quality of life. For patients with PVRL alone without central nervous system involvement, ophthalmology treatment is necessary to control patient's eye symptoms, and close follow-up should be followed to find the involvement of the central nervous system in time, and then combined with neurological treatment to save patient’s lives.
ObjectiveTo investigate the clinical characteristics, treatment and prognosis of primary vitreoretinal lymphoma (PVRL) diagnosed and treated in our hospital during the past 10 years. MethodsA retrospective clinical study. From 2011 to 2021, 126 eyes of 67 patients with PVRL who were diagnosed and treated in Department of Ophthalmology, Eye-ENT Hospital, Fudan University were included in the study. Among them, there were 23 males (34.3%, 23/67) and 44 females (65.7%, 44/67); the average age was 57.1 years. There were 59 cases with both eyes (88.1%, 59/67) and 8 cases with one eye (11.9%, 8/67). At the initial eye diagnosis, 22 cases had a clear history of primary central nervous system lymphoma (PCNSL); 5 cases were found to have intracranial lesions by head imaging examination; 40 cases had no central nervous system involvement. Twenty cases were treated with glucocorticoids due to misdiagnosed uveitis. All patients received intravitreal injection of methotrexate (IVM) treatment. The treatment regimen was twice a week in the induction period for 2 weeks, once a week in the consolidation period for 1 month, and once a month in the maintenance period. Patients with PCNSL or both eyes received concurrent systemic chemotherapy (chemotherapy), and some in combination with radiation therapy to the brain (radiotherapy). The mean follow-up time was 39.3 months. The clinical manifestations, treatment and prognosis of the patients were retrospectively analyzed. The visual acuity before and after treatment was compared by t test. ResultsAmong the 22 cases with a clear history of PCNSL at the initial eye diagnosis, the average time from intracranial diagnosis to eye diagnosis was 22.9 months. Among the 40 cases without central nervous system involvement at first, 14 cases (20.9%, 14/67) developed central nervous system lesions during follow-up period. The mean time from ocular diagnosis to intracranial diagnosis was 9.9 months. Among the 126 eyes, 42 eyes (33.3%, 42/126) had anterior segment inflammation. vitreous inflammation type, retinal type, and vitreous retinal type were 58 (46.0%, 58/126), 7 (5.6%, 7/126), and 61 (48.4%, 61/126) eyes, and 9 of them (7.1%, 9/126) had optic nerve involvement at the same time. Patients received an average of 12 IVM treatments. IVM combined with systemic chemotherapy in 59 cases (88.1%, 59/67), of which 16 cases were combined with brain radiotherapy. All patients achieved complete remission after completing the treatment cycle (100.0%, 67/67). After treatment, 21 eyes (16.7%, 21/126) had ocular recurrence; 22 (32.8%, 22/67) had intracranial recurrence; 8 cases (11.9%, 8/67) died. The mean progression-free survival of patients was 23.7 months; the mean survival time was 43.6 months; the 5-year overall survival rate was 72.5%. ConclusionsThe manifestations of PVRL are complex and diverse, and most of them are accompanied by involvement of the central nervous system. It can be divided into vitreitis type, retinal type and vitreoretinal type, and the optic nerve can be involved at the same time; IVM combined with systemic treatment can completely relieve the disease.
ObjectiveTo investigate the clinical, imaging features, diagnosis, treatment and prognosis of pulmonary lymphomatoid granulomatosis (PLG).MethodsA case of PLG confirmed by autopsy and pathology was reported, and the related literature was reviewed.ResultsA 44-year-old male patient presented with cough, expectoration and shortness of breath as the main symptoms. The imaging findings of lung CT were diffuse vascular nodular and patchy changes in the lungs, especially in the lower lung. Clinical symptoms were not relieved with anti-infection and symptomatic treatment. The patient's condition gradually exacerbated and finally died. The autopsy revealed PLG with pathological grade Ⅲ. The infiltration of lymphocytes centered with blood vessel and necrosis were observed under light microscope. EBER in situ hybridization was positive. Totally 28 Chinese articles and 34 foreign articles were screened out. Literature review suggested that PLG usually occurred in middle-aged men and was associated with EBV infection. It is frequent with immunodepression. Its clinical symptoms were atypical. The main imaging manifestations were multiple nodules and masses more frequent along the bronchovascular bundle. A diagnosis of PLG depended on pathological histology, immunohistochemistry and EBER in situ hybridization. Surgery was the main treatment for local lesions. The patients of grade I and Ⅱ with rapid progress and all grade Ⅲ were usually treated with RCHOP regimen combined with chemotherapy. The prognosis was correlated with grading. Grade Ⅲ was aggressive and the prognosis was poor.ConclusionsPLG is an atypical pulmonary lymphoproliferative disorder. It can be seen in many immunosuppressive diseases. The CT imaging features of PLG have certain characteristics, but the final diagnosis should be combined with pathological diagnosis. Some patients can be relieved by treatment, and patients with grade Ⅲ have poor prognosis.
ObjectiveTo investigate the clinical characteristics and prognosis of pneumocystis pneumonia (PCP) in patients with lymphoma. MethodsTwenty inpatients who were diagnosed as lymphoma with PCP in PLA 307 Hospital from March 2012 to December 2014 were retrospectively analyzed. ResultsAll patients got non-Hodgkin's lymphoma. Specific genes for Pneumocystis jirovecii were found in the sputum of 5 patients and the bronchoalveolar lavage fluid of the other 15 patients. The major clinical presentations were fever (18/20) and dyspnea (13/20). Arterial blood gas analysis showed that all patients had hypoxaemia. There were 10 patients with respiratory failure (10/20), in which 7 patients needed mechanical ventilation (7/20). Four patients died (4/20). All patients were treated by multiple chemotherapy. Fifteen patients (75%) had leukocytopenia, with an average white blood cell (WBC) count of (3.2±2.8)×109/L. The mean lactate dehydrogenase (LDH) level was (374.6±197.2) U/L. The mean APACHEⅡ score was 12.6±4.4. PCP had no significant manifestations under the bronchoscope. Imaging manifestations were ground-glass opacities expanding to periphery from the hila, but the pleura was less involved. Univariate analysis revealed that there were no significant differences in chemotherapy cycle, WBC count or G test between the survival group and the death group. However, serum LDH, APACHEⅡ score, delay diagnosis, and co-infection were statistically significant between the two groups. ConclusionsThe main clinical presentations of PCP patients with lymphoma are fever and progressive exertional dyspnea. High LDH, high APACHEⅡ score, diagnosis delay and co-infection indicate poor prognosis.
ObjectiveTo explore the clinical characteristics, diagnosis and treatment methods of pulmonary mucosa-associated lymphoid tissue lymphoma. MethodsClinical manifestations, laboratory examinations, imaging, diagnosis and treatment data of 23 patients with pulmonary mucosa-associated lymphoma were collected and related literatures were reviewed. ResultsAmong the 23 patients, 14 were males and 9 females, aged 22 to 71 years old, with a median age of 58 years old. Seven patients were found in physical examination, 15 patients showed respiratory symptoms, and 1 patient was diagnosed with flatness on percussion. According to the pulmonary CT scan, 10 patients showed large consolidations, 9 patients showed mass shadows with air bronchograms, 10 patients showed nodular shadows, 1 patient showed small reticular shadows, and 1 patient was observed with subcarinal mass in the mediastinum; 1 patient was observed with a decreased lung volume. Immunohistochemistry examination showed CD20 (+), cyclind-1 (-), and Ki-67 index was from 5% to 25%. Ten patients were treated with chemotherapy, 9 patients were treated with surgery, 1 patient was treated with radiotherapy and surgery, and 3 patients were untreated. ConclusionsPulmonary mucosa-associated lymphoid tissue lymphoma is a low-moderate malignant tumor, with insidious clinical onset, and patients usually go for treatment due to physical examination and mild respiratory symptoms. Imaging findings are mainly pulmonary consolidation and mass shadows associated with air bronchograms. Confirmed diagnosis is primarily made by pathology and immunohistochemistry. Currently, there is still some controversy over a variety of treatment options, including observation, surgery, surgery combined with chemotherapy, chemotherapy alone, and radiotherapy. The patients' prognosis and survival time are both excellent.
ObjectiveTo summarize experience of clinical diagnosis and treatment for liver posttransplant lymphoproliferative disorder(PTLD). Method The clinical diagnosis and treatment processes of 3 patients with live PTLD in this hospital were retrospectively analyzed and the relevant literatures were reviewed. ResultsThe EB virus was negative and CD20 was positive for these 3 patients with liver PTLD, the time of onset was 10 to 12 years after liver transplantation, and the tacrolimus was given for anti-immune following liver transplantation. The pathological diagnosis was diffuse large B cell lymphoma for all the patients. ConclusionsWith use of large quantities of immunosuppressive drugs following liver transplantation, incidence of liver PTLD gradually rises. Meanwhile, prognosis is poor and early diagnosis is difficult. Currently, diagnosis and classification is still dependent on pathological examination. EB virus positive patients show earlier onset, while EB negative patients show later onset with a poorer prognosis. Therefore, a long-term follow-up should be conducted for early detection, and rituximab should be administrated to patients with CD20(+).
