Purpose: Traditionally the patients with early stage non-Hodgkin's lymphoma of the head and neck was treated with radiotherapy. But the results were not satisfactory due to distant relapse. Although combined treatment with radiotherapy and chemotherapy was tried with some improved results and chemotherapy alone was also tried in recent years, the choice of treatment for the patients with early stage non-Hodgkin's lymphoma of the head and neck has not been defined Therefore, in order to determine the optimum treatment method, we analysed retrospectively the outcomes of the patients with Ann Arbor stage I and II non-Hodgkin's lymphoma localized to the head and neck who were treated at Severance Hospital. Materials and Methods: 159 patients with stage I and II non-Hodgkin's lymphoma localized to the head and neck were treated at our hospital from January, 1979 to December, 1992. Of these patients, 114 patients whose primary sites were Waldeyer's ring or nodal region, and received prescribed radiation dose and/or more than 2 cycles of chemotherapy. were selected to analyze the outcomes according to the treatment methods ( radiotherapy alone, chemotherapy alone. and combined treatment with radiotherapy and chemotherapy ). Results: Five year overall actuarial survival of the patients whose Primary site was Waldeyer's ring was $62.5\%.$ and that of the Patients whose primary site was nodal region was $53.8\%$ There was no statistically significant difference between survivals of both groups. Initial response rate to radiotherapy. chemotherapy, and combined treatment was $92\%,\;83\%,\;94\%$ respectively, and 5 year relapse free survival was $49.9\%,\;52.4\%,\;58.5\%$ respectively ( statistically not significant ). In the patients with stage I. 3 year relapse free survival of chemotherapy alone group was $75\%$ and superior to other treatment groups. In the Patients with stage II, combined treatment group revealed the best result with $60.1\%$ of 3 year relapse free survival. The effect of sequential schedule of each treatment method in the Patients who were treated by combined modality was analyzed and the sequence of primary chemotherapy + radiotherapy + maintenance chemotherapy showed the best result ( 3 year relapse free survival was $79.1\%).$ There was no significant survival difference between BACOP regimen and CHOP regimen. Response to treatment was only one significant (p(0.005) prognostic factor on univariate analysis and age and mass size was marginally significant ( p(0.1). On multivariate analysis, age (p=0.026) and mass size (p=0.013) were significant prognostic factor for the relapse free survival. Conclusion: In summary, the patients who have non-Hodgkin's lymphoma of the head and neck with stage I and mass size smaller than 10 cm, can be treated by chemotherapy alone, but remainder should be treated by combined treatment method and the best combination schedule was the sequence of initial chemotherapy followed by radiotherapy and maintenance chemotherapy.

Background: Data regarding childhood and adolescent non Hodgkin lymphomas in Iran are limited. The aim of this study was to assess the epidemiological and histomorphological features and survival of affected patients in our center. Materials and Methods: The clinicopathologic features and outcome of 44 children and adolescents with non Hodgkin lymphoma diagnosed during 2004-2012, were investigated retrospectively. The influence of potential prognostic parameters in overall survival was investigated by log-rank test and Cox regression analysis. Results: The mean age at presentation was $13.8{\pm}6.16$ years with a male predilection (M: F=3:1). Malignant lymphoma, not otherwise specified, diffuse large cell lymphoma and Burkitt lymphoma were the three most common histological types observed. The tumors were 36.4% intermediate grade, 27.3% high grade and 34.1% belonged to the malignant lymphoma not otherwise specified group. Immunohistochemistry findings were available in 39 cases. Out of these cases 33 (84.6%) had B cell lineage, 4 (10.25%) T cell lineage and 2 (5.12%) of the cases belonged to miscellaneous group. 3 year and 5 year survivals were 48% and 30% respectively and median survival was 36 months (95%CI=21.7-50.3 months). Overall survival in patients with high grade tumors was 19.5 months, in the intermediate group,79 months, and for malignant lymphomas not otherwise specified it was 33.6 months (p value=0.000). Conclusions: The survival rate for children and adolescents with non Hodgkin lymphomas at our center during 2004-2012 was at a low level.

Purpose: Primary malignant lymphomas of the salivary glands are uncommon, representing only 1.7% to 3.1% of all salivary neoplasms and 0.6% to 5% of all tumors and tumor-like lesions of the parotid gland. Lymphomas of the parotid glands are usually manifestations of a systemic disease process but primary lymphomas of the parotid glands are rare. Most of these lesions are classified as extranodal non-Hodgkin's lymphoma. We report the clinicopathological features of primary malignant lymphoma of the parotid gland based on an analysis of our cases. Methods: The subject was a 48-year-old male patient with a malignant lymphoma originating in the parotid gland, which had been slowly increasing in size over previous 6 months. The diagnosis was established by MRI and a superficial lobectomy. After diagnosis, the patient was referred to an oncologist for staging and medical treatment. Results: The stage was IIIA. The patient was treated with chemotherapy following surgery with rituximab and CHOP (Cyclophosphamide, Adriamycin, Vincristine, Prednisolone). The tumor was controlled successfully by chemotherapy. The patient was followed up for 1 year with no relapse. Conclusion: A case of primary non-Hodgkin's lymphoma of the parotid gland was treated with a superficial parotidectomy and chemotherapy. The disease was well controlled after a 1 year follow-up.

Small cell carcinoma of the lung is characterized by cells with finely stippled chromatin and scanty cytoplasm as well as a particularly aggressive clinical course and favorable response to the chemotherapy. Recently percutaneous fine needle aspiration (FNA) biopsy has become both widely established and highly respected for the diagnosis of lung cancer. However metastatic small cell carcinoma of lymph node should be cytologically differentiated from the small round cell tumor of particular sites, especially malignant lymphoma, because small ceil carcinoma of classic oat cell type nay simulate small cell non-Hodgkin's lymphoma. We report five cases of metastatic small cell carcinoma of in-termediate cell type diagnosed by FNA of the enlarged lymph nodes of the neck and axilla. The cytologic smears contained diffuse small neoplastic cells larger than lymphocytes with dense, pyknotic nuclei and extremely scanty cytoplasm. Apparently viable large tumor cells have vesicular nuclei with granular, sometimes very coarse chromatin. The characteristic cytologic features of small cell carcinoma as compared to malignant lymphoma were as follows.: 1) small cells with dense pyknotic nuclei are evenly distributed in the background of apparently viable larger tumor cells, admixed with mature lymphocytes and phagocytic macrophages. 2) small loose aggregates of cells with nuclear melding are indicative of small cell carcinoma rather than non-Hodgkin's lymphoma. 3) the cytoplasmic and nuclear fragments of tumor necrosis are more dominant in the smears of small cell carcinoma. 4) nuclear membrane and nucleoli are generally indistinct in small cell carcinoma due to condensation of chromatin.

Background and Aim: The incidence of extra nodal non Hodgkin lymphoma (ENL) is rising throughout the world. However, data regarding ENL as a group is limited. The aim was to study the epidemiological and histomorphological trends of primary ENL (pENL) in India. Material and Methods: The biopsy materials from sixty eight patients with pENL (45 male, 23 female, M:F= 1.9:1), diagnosed over a five year period (2005-2009), were analysed and pathologically reclassified according to the World Health Organization (WHO) classification, 2008 criteria. Results: Primary extra nodal non Hodgkin lymphomas constituted 22.0% (68/308) of all non Hodgkin lymphomas (NHL). The mean age at presentation for pENL and primary nodal NHL was 43 years and 58 years, respectively with a male predilection (M: F=2:1). Central nervous system (CNS) constituted the most common extranodal site (20/68, 29.5%) followed by gastrointestinal tract (17/68, 25%), and nose/nasopharynx (8/68, 11.8%). Diffuse large B-cell lymphoma (DLBCL, not otherwise specified), extranodal marginal lymphoma of mucosa associated lymphoid tissue (MALT) type, and B cell NHL unclassified (U) were the three most common histological types observed. T-cell phenotype was rarely noted (4%). Follicular lymphomas and anaplastic large cell lymphoma, seen among nodal NHL, were absent at extra nodal sites. Majority (41/68, 60%) of the patients with pENL were immunocompetent and 55% were in stage I-II with favorable prognosis. Conclusion: Central nervous system was the most common site of ENL, followed by gastrointestinal tract. Majority of pENL occurred in immunocompetent hosts with a favorable prognosis.

The increasing risk of subsequent malignancy after treatment of malignant lymphoma is well known, which is mainly due to longer survival of these patients. Radiotherapy at an early stage of Hodgkin's disease or non-Hodgkin's lymphoma is accepted to be associated with future occurrence of secondary thyroid cancer. Nevertheless, the synchronous presentation of these malignancies is extremely rare. Well differentiated thyroid cancer, a slow-growing tumor that responds to therapy with surgery and radioactive iodine, is associated with prolonged survival. therefore, it is important to make this diagnosis in patients who show evidence of malignant lymphoma. Furthermore, appropriate treatment must be considered for thyroid cancer to improve the prognosis of these patients. We herein reported 4 cases of synchronous thyroid cancer and malignant lymphoma in patients who had not previously recieved radiotherapy or chemotherapy.

The incidence and prevalence, the second most common lymphoid malignancy after leukemia, are both increasing. The distribution of lymphoma varies among sexes, age groups, and sites. In Indonesia, information about the incidence of lymphoma and its characteristics are insufficient. Therefore, this study was performed to evaluate the incidence of lymphoma and features based on age group, sex, site, clinical diagnosis, and histopathological type in Indonesia. This study is an observational analytical study with a cross-sectional design aimed to evaluate the histopathological profile of lymphoma in Yogyakarta from 2010-2014. It was based on secondary data from Anatomic Pathology Department's medical records from several hospitals and laboratories. The result showed an increased incidence of lymphoma in Yogyakarta in 2010-2014 (p=0.039). Lymphoma mostly occurred in age range 45-64 years (p=0.004), dominated by male with ratio 1.6:1. DLBCL was found to be the most common histopathological type (44.4%). Sex, age, and clinical diagnosis demonstrated statistically significant correlations with the histopathological type (p<0.001). In conclusion, the incidence of lymphoma has significantly increased from 2010-2014. There are statistically significant correlations between gender, age, and clinical diagnosis with the histopathological type of lymphoma.

Background: The presence of Epstein-Barr virus (EBV) in Non-Hodgkin's lymphoma can be identified by immunohistochemistry for detection of EBV latent membrane protein (LMP). The role of EBV as an etiologic agent in the development of non-Hodgkin lymphoma has been supported by detection of high levels of latent membrane protein 1 (LMP-1) expression in tumors. However, no study has been conducted in a Pakistani population up till now to determine the frequency of Epstein-Barr virus positivity. The objective of our study was to determine a value for non-Hodgkin lymphoma patients using EBV LMP-1 immunostaining in our institution. Materials and Methods: This study was carried out at the Department of Histopathology, Armed Forces Institute of Pathology (AFIP), Pakistan from December 2011 to December 2012. It was a cross sectional study. A total of 71 patients who were diagnosed with various subtypes of NHL after histological and EBV LMP-1 immunohistochemical evaluation were studied. Sampling technique was non-probability purposive. Statistical analysis was achieved using SPSS version 17.0. Mean and SD were calculated for quantitative variables like patient age. Frequencies and percentages were calculated for qualitative variables like subgroup of NHL, results outcome of IHC for EBV and gender distribution. Results: Mean age of the patients was $53.6{\pm}16$ years (Mean${\pm}$SD). A total of 50 (70.4%) were male and 21 (29.6%) were female. Some 9 (12.7%) out of 71 cases were positive for EBV-LMP-1 immunostaining, 2 (22.2%) follicular lymphoma cases, 1 (11.1%) case of T-cell lymphoblastic lymphoma, 4 (44.4%) cases of diffuse large B cell lymphomas, 1 (11.1%) mantle cell lymphoma and 1 (11.1%) angioimmunoblastic T cell lymphoma case. Conclusion: In our study, frequency of EBV in NHL is 12.7% and is mostly seen in diffuse large B cell lymphoma. This requires further evaluation to find out whether this positivity is due to co-infection or has a role in pathogenesis.

Non-Hodgkin's Lymphoma(NHL) is a malignant tumor that is derived from the lymphatic system. The most common symptoms of NHL are painless lymph node enlargement. However, we should not diagnose NHL by only fragmentary clinical symptom and radiologic finding because of the various lymphoma characters. We have treated a patient with such preoperative findings of Branchial cleft cyst. However, the pathologic diagnosis of the surgical specimen was diffuse large b-cell lymphoma.
