原发性乳腺淋巴瘤研究进展

原发性乳腺淋巴瘤(primary breast lymphoma,PBL)是一种罕见的结外型淋巴瘤,最常见的病理类型为弥漫大B细胞淋巴瘤,近年来隆胸相关的间变大细胞淋巴瘤亦被界定为新的临床类型。其与乳腺癌相比,临床表现和影像学检查均无特异性,需依靠病理活检及免疫组化明确诊断,预后较差。目前PBL尚无标准治疗方案,但趋向于以环磷酰胺+阿霉素+长春新碱+泼尼松(cyclophosphamide+doxorubicin+vincristine+prednisolone,CHOP)方案化疗为主的综合治疗方案,避免采用扩大的手术治疗。     

系统性种痘水疱病样皮肤T细胞淋巴瘤1例及文献复习

目的:通过分析系统性种痘水疱病样淋巴瘤病例1例,结合文献回顾,分析其临床特点、诊断治疗进展及预后,以提高临床医生对该病的认识。方法:报道1例有7年种痘水疱病史并转化为系统性T细胞淋巴瘤病例,通过皮肤活检、病理及免疫组化、TCR基因重排、实验室、MRI及影像学检查,确定诊断及治疗方案,并观察预后。后进行文献回顾。结果:本例患者的主要临床表现为多年的面部红斑、丘疱疹及水疱改变,最初诊断为"种痘水疱病",初期治疗有效,病情反复并进展,皮肤改变加重,病变逐渐累及鼻中隔及下鼻甲,出现坏死及缺损,同时伴有发热及淋巴结肿大等系统症状。皮肤病理及免疫组化提示真皮弥漫性淋巴细胞、浆细胞浸润,CD3+,CD4+,CD8散在细胞+,CD30局部细胞+,CD56局部细胞+,EBER杂交(+),Ki-67增殖指数为60%。TCR基因克隆性重排。经干扰素及激素治疗初期病情控制尚可,持续约7年时间,后病情进行性加重,表现系统性种痘水疱病样皮肤T细胞淋巴瘤症状,给予MESA方案化疗1次。化疗后病情稳定,鼻部症状明显改善。后病情进展,患者出现神经系统症状并死亡。结论:种痘水疱病样淋巴瘤早期临床表现易与种痘样水疱病相混淆,但根据其病变部位病理活检及免疫组化分析可得到确诊,早期单纯皮肤病变期可持续数年,部分对激素及干扰素治疗有效。当发展为系统性种痘水疱病样淋巴瘤期时,病情进展迅速,常可累及中枢神经系统,对于化疗反应差,预后不佳,死亡率极高。化疗对于该病的有效性有待进一步观察。

Primary Adrenal Lymphoma: a Single-Center Experience

Objective: To describe the clinical presentation, biochemistry, imaging features, and treatment outcome of patients with primary adrenal lymphoma (PAL) presenting to a single tertiary care center.Methods: We performed a retrospective analysis of case records of 7 patients diagnosed with PAL between January 2011 and May 2014 at our institution in Mumbai, India.Results: Median age of presentation in our series was 48 years (range, 41 to 60 years), with a male to female ratio of 6:1. Bilateral adrenal involvement was seen in 4 of 7 patients (58%). Adrenal insufficiency (AI) was seen in 3 of the 4 patients with bilateral involvement (75%). Computed tomography showed slight to moderate contrast enhancement of adrenal masses in 4 of 5 patients (80%). Diffuse, large, B-cell lymphoma (DLBCL) was the most common immunophenotype (85%). One patient died due to rapid disease progression even before starting chemotherapy. Six patients were treated with chemotherapy and/or external beam radiotherapy. After 1 year, 2 more patients had died, whereas 4 patients were in remission.Conclusion: PAL should always be considered in differential diagnosis of bilateral adrenal mass with AI. DLBCL is the most common histologic subtype of PAL. Despite treatment, long-term prognosis of PAL remains poor.Abbreviations: AI = adrenal insufficiency B/L = bilateral CT = computed tomography DLBCL = diffuse, large, B-cell lymphoma EBRT = external beam radiotherapy ¹⁸F-FDG PET/CT= ¹⁸F-fluorodeoxyglucose positron emission tomography/computed tomography PAL = primary adrenal lymphoma T/NK = T cell/natural killer cell     

Lennert's lymphoma

Four cases (3 M, 1 F) of Lennert's lymphoma were presented. The age (38-76 years), the clinical aspect and the morphopathological features were characteristic. Despite an intensive chemotherapy, 3 of the 4 patients died between 2 and 16 months (mean survival time 7 months). The controversies about the nosological delimitation and the cellular nature of Lennert's lymphoma are presented. Because of the poor prognosis, it should be considered as a high-grade malignant non-Hodgkin lymphoma.     

Human Papillomavirus and Epstein-Barr virus co-infection in Cervical Carcinoma in Algerian women

Purpose

To present a possible coincidence of cytomegalovirus retinitis and intraocular lymphoma in a patient with systemic non-Hodgkin’s lymphoma.

Case presentation

A 47-year-old woman presented with decreased visual acuity associated with white retinal lesions in both eyes. A history of pneumonia of unknown aetiology closely preceded the deterioration of vision. Five years previously the patient was diagnosed with follicular non-Hodgkin’s lymphoma. She was treated with a chemotherapy regimen comprised of cyclophosphamide, adriamycin, vincristin, and prednisone with later addition of the anti-CD20 antibody rituximab. She experienced a relapse 19 months later with involvement of the retroperitoneal lymph nodes, and commenced treatment with rituximab and ⁹⁰Y-ibritumomab tiuxetan. A second relapse occurred 22 months after radioimmunotherapy and was treated with a combination of fludarabine, cyclophosphamide, and mitoxantrone followed by rituximab. The patient experienced no further relapses until the current presentation (April, 2010). Pars plana vitrectomy with vitreous fluid analysis was performed in the right eye. PCR testing confirmed the presence of cytomegalovirus in the vitreous. Atypical lymphoid elements, highly suspicious of malignancy were also found on cytologic examination. Intravenous foscarnet was administered continually for three weeks, followed by oral valganciclovir given in a dose of 900 mg twice per day. In addition, the rituximab therapy continued at three monthly intervals. Nevertheless, cessation of foscarnet therapy was followed by a recurrence of retinitis on three separate occasions during a 3-month period instigating its reinduction to the treatment regime after each recurrence.

Conclusions

Cytomegalovirus retinitis is an opportunistic infection found in AIDS patients as well as in bone marrow and solid organ transplant recipients being treated with systemic immunosuppressive drugs. This case presents a less common incidence of cytomegalovirus retinitis occurring in a patient with non-Hodgkin’s lymphoma. We demonstrated a possible coexistence of cytomegalovirus retinitis and intraocular lymphoma in this particular patient. The final diagnosis was based on clinical manifestations together with the course of uveitis and its response to treatment alongside the results of vitreous fluid analysis. This report highlights the importance of intraocular fluid examination in cases with nonspecific clinical manifestations. Such an examination allows for the detection of simultaneously ongoing ocular diseases of differing aetiologies and enables the prompt initiation of effective treatment.     

21例淋巴瘤合并肺部侵袭性真菌感染的回顾性临床分析

摘要 目的：探讨淋巴瘤合并肺部侵袭性真菌感染( IPFI ) 的高危因素、临床特征和诊疗方案。方法：回顾性分析2019-2020年血液科收治的淋巴瘤合并IPFI患者的临床资料。结果：化疗后出现IPFI的淋巴瘤患者共计21例,总发病率为2.7%,平均年龄60岁,男性占77.8%,其中确诊5例、临床诊断7例、拟诊8例,确诊患者的病原菌为白色念珠菌（80%）和曲霉菌（20%）。肺部CT影像特征不典型,大多表现为弥漫、散在的斑片状絮样密度增高影、结节影,双肺受累多见,在接受一线抗真菌治疗后有18例患者缓解,总有效率为90.4%,其中原发病终末期患者及合并细菌感染患者死亡率高,预后差。结论：老年、男性、原发病控制不佳、高强度或大剂量化疗以及糖皮质激素的使用可能是淋巴瘤IPFI的高危因素,早期临床症状和影像学检查缺乏特异性,常规病原学检出率仍较低,1-3-β-D-葡聚糖试验（G试验）、半乳甘露聚糖试验（GM试验）结合肺部CT检查有助于早期诊断,一线抗真菌药物的使用可显著改善患者预后。     

Magnetic resonance imaging findings in primary lymphoma of the liver: a case report

ABSTRACT: INTRODUCTION: Primary lymphoma of the liver is an extremely rare finding, with the few such cases reported in the literature to date describing indeterminate imaging findings, being focused more on computed tomography. To the best of our knowledge, there is no prior report describing magnetic resonance imaging scan findings with such a lesion. In the case reported here, magnetic resonance imaging gave us the opportunity to ascertain the correct diagnosis, confirmed by histopathology, thus avoiding unnecessary surgery or other treatments. Although this condition is rare, knowledge of magnetic resonance imaging findings will be invaluable for radiologists and other medical subspecialties that may face such cases in the future in helping to provide adequate management for affected patients. CASE PRESENTATION: A focal lesion was incidentally detected by ultrasound in a 75-year-old asymptomatic Albanian man being treated for benign hypertrophy of prostate. Chest and abdomen computed tomography scans did not reveal any abnormal findings besides a solid focal lesion on the right lobe of the liver and a mild homogenous enlargement of the prostate gland. Subsequently, magnetic resonance imaging of the upper abdomen was performed for better characterization of this lesion. Our patient was free of symptoms and his laboratory test results were normal. CONCLUSIONS: The magnetic resonance imaging scan results showed some distinctive features that helped us to make the correct diagnosis, and were thus very important in helping us provide the correct treatment for our patient.     

Primary mediastinal large B-cell lymphoma in HIV: report of two cases

Primary mediastinal large B cell lymphoma (PMLBCL) is a subtype of diffuse large B cell lymphoma arising in the mediastinum with distinctive clinical and morphological features. Though diffuse large B cell lymphoma is one of the most common non-Hodgkin lymphoma associated with AIDS, there are no data available regarding the association of HIV and PMLBCL. We report here two cases of PMLBCL arising in AIDS patients. In both cases, PMLBCL presented in a setting of low CD4 T-cell count as rapidly enlarging mediastinal mass. The morphologic and immunophenotypic findings are characteristic of PMLBCL. One of the two patients, a 25-year-old woman who had localized disease and evidence of Epstein–Barr virus in lymphoma cells, did not respond to chemotherapy and died of disease progression 5 months after diagnosis. The second patient, a 38-year-old male with disseminated disease, responded to therapy and is disease-free after 9 months of follow-up.     

原发性胃淋巴瘤临床与内镜特征分析

目的:探讨影像学检查及胃镜、超声内镜对原发性胃淋巴瘤的术前诊断方法,以提高该疾病的术前诊断率。方法:总结我院经手术及病理证实的21例原发性胃淋巴瘤资料,评估胃镜活检、超声内镜及CT对该病诊断的作用。结果:21例术前CT检查,误诊为浸润型胃癌11例,间质瘤2例,未见明显异常3例。CT术前诊断率为23.8%(5/21)。全部患者均实施胃镜检查,活检病理诊断淋巴瘤14例,胃镜活检诊断率为66.7%(14/21)。其中10名患者实施超声胃镜检查,判断胃淋巴瘤6例、胃癌3例、间质瘤1例;术前诊断率为60.0%(6/10)。结论:胃镜及超声内镜是原发性胃淋巴瘤的主要术前诊断方式;CT扫描能明确有无纵隔及腹腔内淋巴结肿大,为原发性胃淋巴瘤提供诊断依据。     

Diagnosis and surgical treatment of multiple endocrine neoplasia type 2A

Background

This study aims to introduce the diagnosis and surgical treatment of the rare disease multiple endocrine neoplasia type 2A (MEN 2A).

Methods

Thirteen cases of MEN 2A were diagnosed as medullary thyroid carcinoma (MTC) and pheochromocytoma by biochemical tests and imaging examination. They were treated by bilateral adrenal tumor excision or laparoscopic surgery.

Results

Nine patients were treated by bilateral adrenal tumor excision and the remaining four were treated by laparoscopic surgery for pheochromocytoma. Ten patients were treated by total thyroidectomy and bilateral lymph nodes dissection and the remaining three were treated by unilateral thyroidectomy for MTC. Up to now, three patients have died of MTC distant metastasis.

Conclusions

We confirmed that MEN 2A can be diagnosed by biochemical tests and imaging examination when genetic testing is not available. Surgical excision is the predominant way to treat MEN 2A; pheochromocytoma should be excised at first when pheochromocytoma and MTC occur simultaneously.     

Cytomorphologic diagnosis of malignant lymphoma arising in the heart: a case report.

BACKGROUND: Primary malignant lymphoma of the heart is extremely rare. Because its clinical signs and symptoms are typically nonspecific, it is often very difficult to detect cardiac involvement while the patient is alive. We describe a case of malignant lymphoma involving predominantly the heart and pericardium and diagnosed by pericardiac effusion cytology antemortem. CASE: An 83-year-old woman presented with dyspnea on exertion. Echocardiography revealed a low-echoic tumor mass close to the right ventricular wall and massive pericardiac effusion. Diagnosis of diffuse large B-cell lymphoma was made by cytomorphologic examination and flow cytometry of the tumor cells obtained from the effusion. Although chemotherapy was instituted immediately, the patient died of progressive heart failure. Diffuse large B-cell lymphoma predominantly involving the intracardiovascular region was confirmed at autopsy. CONCLUSION: From the experience in this case, we conclude that cytopathologic examination of sonographically guided aspiration of the cardiovascular region is very useful for antemortem diagnosis of primary malignant lymphoma of the heart.
