Castleman's disease (CD) is an uncommon lymphoproliferative disorder. The disease entity is classified into 2 clinical subtypes, unicentric and multicentric type. Prevalence of lymphoid malignancy in multicentric CD (MCD) is very low. In this case, we report a case of 77 years old woman who developed high fever and swelling in both side of her neck. Neck lymph node biopsy revealed plasma cell hyperplasia. Patient's symptom was subsided after treatment with Dexamethasone. Three months later, multiple lymph node enlargement was developed in abdomen and neck area again. Repeated neck lymph node biopsy confirmed diffuse large B cell lymphoma. The patient started chemotherapy.

The primary lymphoma in the lung is very rare. Moot of the primary pulmonary lymphomas, which represent 3-4 % of extra-nodal lymphomas, are low-grade B-cell lymphoma. The low-grade B-cell lymphomas progress slowly and the prognosis of these are more favorable than that of the nodal lymphomas. However, high-grade forms progress rapidly with more severe course. The diagnosis of primary pulmonary lymphomas generally relies on the histopathologic findings of lung specimens obtained by surgical excision of the lesions or open-lung biopsy. Recently, less aggressive biopsies(transbronchial, transthoracic) and/or immunocyto-chemical, immunochemical and gene rearrangement studies on materials obtained by bronchoalveolar lavage have been used occasionally. The treatment of the primary pulmonary lymphomas has not been precisely codified. Several clinical data suggest that limited surgery or non-aggressive chemotherapy can provide long-term survival in patients with such slowly developing neoplasm, and demonstrated the need for the development of noninvasive diagnootic methods. In this study, we report a case of high-grade B-cell lymphoma of the lung which was treated with combination chemotherapy.

Background: Lymphoma is one of the most common malignancies affecting the young Saudi population. This disease has diversified pathologies and clinical stages that necessitate well optimized clinical management. Regular updates of epidemiological behavior of lymphoma from various parts of the world are available but studies from the Kingdom of Saudi Arabia (KSA) in this field are not consistent. Objectives: The aim of this study was to investigate the current trends in presentation and distribution of lymphoma with special reference to incidence and mortality, gender, age, histopathological subtypes, and clinical stages at King Faisal Specialist Hospital and Research Centre (KFSH&RC). Materials and Methods: Our study included lymphoma data from Saudi Cancer Registry, and relative comparison against KFSH&RC tumor registry data, Gulf country data and International Agency for Research on Cancer data. Results: Common tumors in the West (lung, colon, and prostate) were found to be much less frequent in KSA while leukemia, lymphoma and thyroid cancers were more common. Non-Hodgkin Lymphoma (NHL) ranked 3rd most common cancer with age-adjusted incidence of 6/100,000. Estimated age adjusted mortality was 4/100,000 in KSA. There was a peak rise in incidence of lymphoma in 1997-2007. Most common NHL was diffuse large B cell lymphoma at KFSH&RC. A total of 434 cases were diagnosed in 5 years with 55% of them at advanced stage and 35% demonstrating bulky disease and high risk. KFSH&RC registered 35% of Hodgkins and 21% of total NHL identified in entire Saudi Cancer Registry, 2009. Conclusions: Results of this study are very unique, and reveal diverse trends. The findings provide valuable insights in the understanding of current epidemiological features of lymphoma in this part of the world.

Purpose : This study evaluated the treatment outcomes, patterns of failure, and treatment related complications of primary lymphoma patients who received definitive radiation therapy. Materials and Methods : A retrospective analysis was undertaken for 31 patients with primary orbital lymphoma at the Asan Medical Center between February 1991 and April 2001. There were 18 males and 13 females with ages ranging from 3 to 73 years (median, 44 years). The involved sites were 9 conjunctivae, 12 eyelids and 10 other orbits. The histological types were 28 MALT lymphomas (low-grade B-cell lymphoma of mucosa-associated lymphoid tissue type), 1 diffuse large B-cell lymphoma, 1 anaplastic large cell lymphoma and 1 lymphoblastic lymphoma. The Ann Arbor stages were all IE $(100\%)$. Ann Arbor stage III or IV patients were excluded from this study, Bilateral orbital involvement occurred in 6 cases. Radiation therapy was given with one anterior port of high energy electrons $(6\~16\;MeV)$ for the lesions located at the anterior structures like the conjunctivae or eyelids. Lesions with a posterior extension or other orbital lesions were treated with 4 or 6 MeV photons with appropriately arranged portals. In particular, lens blocks composed of lead alloy were used in conjunctival or eyelid lesions. Twelve patients received chemotherapy. The median follow-up period was 53 months. Results : The 5-year overall, cause-specific, and disease-free survival was $91\%,\;96\%,\;and\;80\%$, respectively. The complete response rate 6 months after radiation therapy was $100\%$. Local recurrences were observed in 2 patients at 16 and 18 months after completion of radiation treatment. They were salvaged with additional radiation therapy. Two patients developed distant metastases. A MALT lymphoma patient with a lung relapse was successfully salvaged with radiotherapy, but the other lymphoblastic lymphoma patient with bone marrow relapse expired. There were no severe complications but 5 patients developed radiation-induced cataracts and 2 patients developed dry eye. Conclusion : Most primary orbital lymphomas consisted of MALT lymphomas. Radiation therapy was a successful treatment modality for orbital lymphoma without any severe complications. In cases of local relapses, radiation therapy is also a very successful salvage treatment modality.

Non-Hodgkin's lymphoma is known to be a rare and unusual cause of biliary obstruction. We report a case of biliary obstruction that a 25-year-old male showed icteric sclera and yellow discoloration of his skin caused by metastasis of non-Hodgkin lymphoma. Initial imaging & endoscopic work-up led us to an impression of either cholangiocarcinoma or IgG4-related disease, yet the pathological results weren't diagnostic. Through our thorough re-examination, we found a 5cm sized round, fixed, non-tender sternal mass, and additional imaging studies were suggestive of lymphoma, which was also consistent with the results of incisional chest wall biopsy. Biliary obstruction by lymphoma was successfully treated by endoscopic plastic stent insertion procedure and chemotherapy. Although it is widely accepted that lymphoma accounts for very few portion of malignant biliary obstruction, due to the fact that lymphoma and cholangiocarcinoma are often indistinguishable, careful diagnostic approach should be done.

Background: The aim of this study was to analyze the clinicopathological and immunohistochemical features of primary central nervous system lymphoma (PCNSL) cases occurring in Indian patients and also study the utility of the crush smear preparation in intraoperative diagnosis. Materials and Methods: The immune status, clinical, radiological details, immunohistochemical profile, histopathological findings and cytological features in smear preparation of 32 cases of PCNSL were analyzed. Patients with systemic NHL and skull-base lymphomas were excluded. Results: The mean age of our patients was 52 years with a male: female ratio 1:1. A periventricular location was found in 62.5% of patients. None of our PCNSL cases were associated with AIDS. All cases except one were diffuse large B-cell lymphomas. Intraoperative diagnosis using crush smears allowed correct prediction in 93% of cases. Conclusions: Our study shows that PCNSL is seen predominantly in immunocompetent patients in India. The age of presentation is relatively young as compared to the West. Our study also stresses the utility of crush smear preparation in establishing an intraoperative diagnosis.

Neurolymphomatosis, an uncommon manifestation of non-Hodgkin's lymphoma, is lymphomatous infiltration of peripheral nerves. We confirmed the diagnosis of neurolymphomatosis in a 75-year old woman with a history of complete remission of diffuse large B cell type lymphoma on the nasal cavity seven years ago. She complained of painful weakness of left leg and took the electrophysiologic study, extremity ultrasonography, fluorodeoxyglucose PET-CT, and extremity MRI serially. She was diagnosed as neurolymphomatosis by targeted posterior tibial nerve mass biopsy.

Background: Primary malignant lymphoma of the parotid gland is a rare disease and defined as any malignant lymphoma that first manifests in the parotid gland, regardless of the subsequent stage of the diseases, whether it arises in the parenchyma or intraglandular lymph nodes. This study was performed to review the clinicopathological characteristics of primary parotid lymphoma and identify its optimal treatment modality. Materials and Methods: Six cases with parotid mass as first presentation of malignant lymphoma between 1988 and 2000, were studied on the basis of clinical features, diagnostic tools, treatment modality, treatment outcomes, and clinical stage by Ann Arbor Criteria. All were microscopically reevaluated and classified by NCI working formulation. Results: All patients were males and mean age was 36.7 years (2-66 years). Rapid growing non-tender mass was presented in all the cases and cervical lymphnodes were palpated in 4 cases. However, there was not any evidence of concurrent autoimmune disease such as Sjogren's syndrom or Rheumatoid arthritis. One case was confirmed by surgical specimen after superficial parotidectomy, 2 by excisional biopsy, and 3 by incisional biopsy. The stage of disease by NCI working formulation was IE in 1 patient, IIE in 4 and IV in 1. All were classified into non-Hodgkin' lymphoma, of which there were 5 cases of B-cell type and 1 case of T-cell type. There were 3 diffuse large cell lymphomas, 1 Burkitt lymphoma, 1 MALT lymphoma and 1 T-lymphoblastic lymphoma. Three cases were treated by chemotherapy only, 2 by radiotherapy only and 1 by chemo-radiotherapy. One case with Burkitt lymphoma was died from the disease and one case was lost to follow-up. The others are alive with no evidence of recurrence. Conclusions: Although primary parotid lymphoma is rare and difficult to diagnose preoperatively, most were detected in early stage and showed a relatively good response to the chemotherapy or radiotherapy like other types of extranodal malignant lymphoma.

Primary thyroid lymphoma is rare and accounts for less than 5% of all thyroid malignancy. The clinical presentation includes a rapidly enlarging neck mass, associated with dysphagia, dyspnea or hoarseness. The most common histologic type is diffuse large B cell non-Hodgkin's lymphoma. Papillary thyroid carcinoma is the most common type of thyroid malignancy. Co-occurrence of papillary thyroid carcinoma and primary thyroid lymphoma is very rare. Recently, we experienced a case with co-occurrence of papillary thyroid carcinoma and primary thyroid lymphoma in a 79-year-old woman, who had tuberculous lymphadenitis presented as lateral neck mass. We present this case with a review of the literature.

Purpose: It has been known that PET/CT is very valuable in follow-up study of diffuse large B cell lymphoma (DLBCL). Generally, in DLBCL, radiotherapy and chemotherapy has been progressed, because the lesion hasn‘t been limited to one site. And, it has lead to the decrease of leukocyte like neutropenia, due to myelosuppression of chemotherapy. So, in that case, administration of Filgrastim (Granulocyte colony-stimulating factor; G-CSF) is universal. However, in short time after administration, PET/CT has limitation to offer accurate images, through the uptake of $^{18}F$-FDG is increased in the region that is activated bone marrow by hematopoietic growth. Therefore, the aim of this study is that PET/CT in a certain period of time after administration of Filgrastim is able to show normal degree of $^{18}F$-FDG uptake. Materials and Methods: 10 patients under follow-up study of diffuse large B cell lymphoma were examined in this study from January, 2007 to January, 2009 (Male: 4 persons; Female: 6 persons; The mean age: 53.8 years old; The mean weight: 57.3 Kg). Using PET/CT (Discovery STe; GE Healthcare, Milwaukee, WI, USA), whole body images were acquired in 1 hour after $^{18}F$-FDG injection. For image analysis, each ROI ($120\;mm^2$) was drawn on $C^6$ (the sixth C-spine), $L_4$ (the forth L-spine), liver, spleen, and lung, then SUV (Standard Uptake Value)s were measured. We compared with each uptake between in 1-day and 5~7 days after administration of Filgrastim at same patient, so confirmed significance about these by SPSS version 12. Results: In case of $C_6$, $L_4$, spleen, every SUV of 1 day later was remarkably higher than that of 5~7 days later, but liver and lung were similar. Also, the images acquired after 5~7 days distinct remarkably and show normal degree of $^{18}F$-FDG uptake, because uptake of bone was almost disappeared. Conclusions: In this study, each SUV was prominent difference as a period of time after Filgrastim’s administration. And Filgrastim makes concentrate uptake of $^{18}F$-FDG in bone, but, after 5~7 days, bone‘s uptake was greatly decreased. Therefore, we are able to infer a certain period of time that shows normal degree of uptake, by numerical value proven. Also, we consider that this study contribute to advanced study about the other agent like Pegfilgrastim, Lenograstim besides Filgrastim, afterwards.
