Primary ovarian lymphoma: report of cases and review of literature

Primary female reproductive system lymphomas are distinctly uncommon. We report two cases with primary ovarian non Hodgkin's lymphoma (NHL) having unilateral involvement in one case while the other had bilateral ovarian involvement. Both cases initially presented with ovarian enlargement. The median size of the tumour was 5.8 x 5 cm2. Histologically, by using the WHO classification, one lesion was classified as diffuse small B cell phenotype of intermediate grade and the other as diffuse high grade, B cell phenotype. On the basis of staging studies and clinical follow up, we conclude that both of the neoplasms in the report arose in the ovary. Both of the patients are disease free at 24 months and 6 months of follow up respectively, following excision and chemotherapy. We conclude that that the complete remission and failure free survival of patients with ovarian NHL treated with appropriate treatment appear to be similar to that of patients with extranodal NHL.     

Primary ovarian lymphoma: report of two cases and review of the literature

Ovarian lymphoma is a rare entity. Clinicians should be aware of its clinical manifestations and management since surgery alone often is not adequate treatment. Here, we present two cases of ovarian lymphoma and discuss what is known about ovarian lymphoma.

Primary bone lymphoma: a report of two cases and review of the literature

Primary bone lymphoma (PBL) is an uncommon tumor accounting for approximately 4-5% of extra nodal lymphoma and less than 1% of all non-Hodgkin's lymphoma. Disease may be complicated at presentation by pathological fracture or spinal cord compression. Diffuse large-B-cell lymphoma (DLBCL) accounts for the majority of cases of PBL. Owing to its rarity, only a few retrospective studies have been published addressing the prognosis and treatment of primary bone lymphoma. In this paper, we report our experience with two cases of PBL treated with chemotherapy and radiotherapy and review literature to elucidate the optimal treatment of primary bone lymphoma.     

Primary central nervous system lymphoma. A report of 9 cases and review of the literature

Primary central nervous system (CNS) lymphoma appears to be on the increase. This increase is real rather than due to changes in nosology, physician awareness or increase in high-risk groups. Diagnostic guidelines appear to be well defined and widely accepted. We report 9 cases of primary CNS lymphoma seen at our institution over a 5-year period. The clinical presentation was variable, but consisted mostly of headache, motor dysfunction, and memory and behavioural disturbance. Surgery is of value for diagnosis. In general, surgical decompression is not recommended. Glucocorticoids and radiotherapy appear effective in the short term. The role of chemotherapy is uncertain.     

24例原发纵隔大B细胞淋巴瘤的临床分析并文献复习

背景与目的:原发纵隔大B细胞淋巴瘤(primary mediastinal large B-cell lymphoma,PMBCL)是弥漫大B细胞淋巴瘤的一种亚型,发病率较低。本研究旨在分析其临床特征,探讨合理的治疗模式及预后因素。方法:收集1995年5月至2005年9月于福建省肿瘤医院确诊并接受治疗的24例PMBCL患者的临床资料并行回顾性分析,同时结合文献加以讨论。结果:24例患者中男性16例,女性8例,年龄12～81岁,30岁以下13例。临床Ⅰ Ⅱ期20例,Ⅲ期1例,Ⅳ期3例。有纵隔巨块13例,伴上腔静脉综合征10例,邻近器官受侵14例,乳酸脱氢酶升高15例。初治时11例采用联合化放疗,10例采用单纯化疗,3例采用单纯放疗,完全缓解率41.7%,总有效率91.7%,中位生存期89个月,3年总生存率68.8%,其中初治时达完全缓解者至随访结束时均生存,国际预后指数(international prognostic index,IPI)在本组中未显示预后,多因素分析提示纵隔巨块与预后相关。结论:PMBCL在本组中男性多见,临床表现凶险,须尽快明确诊断。蒽环类为主的化疗联合放疗可取得较好疗效,初治时获得完全缓解尤为关键,伴有巨块者预后差。

Primary non-Hodgkin's lymphoma of the duodenum. Case report and literature review

A case of primary non-Hodgkin's lymphoma of the duodenum is presented. A review of the English literature documented 95 cases, and the presenting signs, symptoms, and radiographic findings have been abstracted. Attention is also drawn to the treatment of 27 cases, 11 of which (41%) survived for 2 or more years. Ten of the 11 long-term survivors were treated with radiotherapy with or without resection, whereas only one long-term survivor was treated by surgery alone.     

原发性心脏淋巴瘤一例并文献复习(英文)

Primary cardiac lymphoma (PCL) is an extremely rare neoplasm and usually defined as a non-Hodgkin’s lymphoma being exclusively located in the heart and/or the pericardium. It is particularly difficult to diagnose this rare disease due to its nonspecific clinical manifestations. The prognosis of this disease is poor. In this diffuse large B-cell lymphoma, the patient finally died of heart failure after 2 courses of chemotherapy with CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone).     

Intraocular lymphoma: report of three cases and review of the literature

Three cases of intraocular lymphoma are presented. One patient had only ocular involvement, one had involvement of the eye and central nervous system, and in the third patient, ocular lymphoma developed 1 year after the diagnosis of a systemic lymphoma. One patient died before treatment could be initiated, but the other two patients responded well to local radiotherapy. Only one patient who received radiation to both eyes and the whole brain, followed by systemic chemotherapy, remains alive 4 years after diagnosis. Eighty-seven cases of intraocular lymphoma reported in the literature are reviewed. Only 16.7% of cases involved the eyes alone without central nervous system or systemic disease. In more than one-half of the cases (59.7%), the eye was the primary site of involvement. Craniotomy or enucleation was required for diagnosis in 52.7% of patients, and diagnosis frequently followed a significant period of delay during which time patients were treated unsuccessfully for uveitis or iritis. Death for most patients was due to progressive central nervous system involvement. Therefore, we recommend combined modality therapy with radiation to the whole brain and both eyes, followed by systemic chemotherapy with or without intrathecal medications.

Primary lymphoma of bone: a case report and review of the literature

The purpose of this study was to investigate the clinical signs and therapy of primary lymphoma of bone (PLB). One primary lymphoma of bone is described, and review of the pertinent literature is introduced. The patient achieved complete remission with no evidence of local recurrence. PLB are uncommon malignancies. Patients with PLB commonly present with local bone pain, soft tissue swelling and a mass or a pathological fracture. Most cases of PLB are classified as diffuse large B-cell lymphomas in the WHO classification of hematological malignancies. Comprehensive immunohistochemical studies are required to establish an accurate histological diagnosis of PLB. Early diagnosis and active treatment can improve the prognosis.     

Primary lymphoma of breast--report of six cases and review of literature.

Six patients of primary lymphoma of breast are presented. All our patients were female with median age of 46 years. Combination chemotherapy was the mainstay of treatment in all the patients. Five patients achieved complete remission of which two relapsed, one had a distant relapse and the other was local. Patient with distant relapse expired after a follow-up of 224 months whereas the one with local recurrence was well controlled with radiotherapy only. The role of combination chemotherapy to decrease the distant relapse and thereby mortality is discussed.     

Primary lymphoma of the parotid gland: a report of twelve cases with a review of the literature

Primary extranodal lymphoma of the salivary gland is an extremely rare disease. In this report we describe twelve cases of primary lymphoma of the parotid gland seen at a single centre, and review the relevant literature. The 12 cases were treated in different departments and did not receive a uniform therapeutic approach. All three patients with Hodgkin's disease are still alive and two are in complete remission after initial radiotherapy. One of these cases developed stage 4 disease and had to receive combination chemotherapy subsequently. Of the 9 non-Hodgkin's lymphoma (NHL) patients, four had low grade NHL and 5 intermediate or high grade NHL. Of these, 2 died with disseminated disease. However, 6 are still alive and well from 1 to 5 years after therapy. These cases were treated with surgery alone, radiotherapy alone or combination chemotherapy with an anthracycline-bearing regimen. Consequently, we are unable to draw any conclusions relating the success of therapy in these cases, nor can we suggest therapeutic guidelines on the basis of this study alone. The treatment of parotid lymphoma is discussed briefly in the light of the available literature. In most cases, symptoms related to an enlarging mass in the parotid region, were evident. In the light of the above data, we suggest that, despite its rarity, lymphoma of the salivary gland should always be considered in the differential diagnosis of a parotid mass. No correlation between lymphoma and Sjogren's syndrome was noted in the present study.     

Primary gastric Hodgkin's lymphoma: a case report and review of the literature

Primary gastric Hodgkin's lymphoma is a rarely encountered lesion. Most cases are observed in the course of systemic disease. Other cases have been reclassified in retrospective studies as non-Hodgkin's lymphomas, after the employment of immunohistochemistry. Some Hodgkin's lymphomas may masquerade non-Hodgkin's lymphomas, and vice versa. Therefore, an accurate diagnosis is important, as treatment and outcome differ significantly for these entities. We report a case of primary Hodgkin's lymphoma arising in the stomach of a 46-year-old male, and discuss the diagnostic approach as well as the differentials of Hodgkin's disease in this anatomic site.
