Objective: To investigate whether the expression level of valosin-containing protein (VCP) is correlated with the prognosis of primary orbital mucosa-associated lymphoid tissue (MALT) lymphoma. Methods: VCP expression in 58 samples from primary orbital MALT lymphoma patients was determined by immunohistochemisty using monoclonal antibodies. Correlations between VCP expression level and prognosis were clarified by statistical analysis. Results: It was found that the percentage of VCP positive cells in samples of primary orbital MALT lymphoma ranged from 32% to 95%. The samples were divided into two groups (level 1 and level 2) according to the median value (45%) of the percentage of VCP positive cells. It was found that the expression level of VCP was significantly correlated with recurrence (P=0.003) and tumor size (P=0.008). At the same time, the 5-year disease-free and overall survival rate of patients of level 1 was significantly better than that of level 2 (P=0.001; P=0.032). There was no observed correlation between the expression level of VCP and other clinical features. Conclusion: VCP could be a useful marker for predicting the prognosis of primary orbital MALT lymphoma.

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.

Background: Non-Hodgkin's lymphoma (NHL) patients demonstrate multiple symptoms in diagnosis and treatment processes. This cross-sectional descriptive study aimed to determine the symptoms and symptom clusters in such patients receiving chemotherapy. Materials and Methods: The study was carried out on a total of 110 inpatients and outpatients receiving treatment in 7 hospitals in Ankara, Turkey. A questionnaire form and the Memorial Symptom Assessment Scale (MSAS) were applied. Percentages, means, t test, one way analysis of variance (ANOVA) and cluster analysis were used for statistical analyses. Results: The most prevalent symptoms in this study were lack of energy, hair loss and change in the way food tastes. The most severe symptoms were hair loss, change in the way food tastes and constipation. The top three most distressing symptoms were taste change, constipation and mouth sores. Seven symptom clusters were determined in this study. Conclusions: Findings of the study will provide an understanding of symptom experiences of Non-Hodgkin's lymphoma patients receiving chemotherapy and will guide determining appropriate nursing interventions. Receiving care of desired quality will contribute to increasing quality of life of affected individuals.

Primary malignant lymphoma of the thyroid gland is uncommon malignancies. Its fine needle aspiration cytology (FNAC) findings are rarely described in the literature. This article highlights the FNAC diagnosis of primary malignant lymphoma of the thyroid gland. A 70-year-old female presented with a rapidly enlarging thyroid mass of five months' duration. FNAC smears showed low cellularity consisting of predominantly atypical enlarged lymphoid cells admixed with a few small lymphocytes, plasma cells, and oncocytic cells. Some disrupted lymphoid cells were also present. The tumor cells infiltrated into the thyroid follicular epithelium forming lymphoepithelial lesion, The cytologic appearance showed a diffuse mixture of cell types with only a few small, mature lymphocytes and many enlaraed lymphoid cells. The enlarged lymphoid cells were atypical and pleomorphic with nuclear clefting and irregularities. Grossly, the left lobe of the thyroid was nearly replaced by a diffuse firm to soft solid mass with smooth tan fish-flesh homogeneous cut surface. Histological diagnosis was diffuse large B-cell lymphoma with areas of marginal zone B-cell lymphoma of MALT type.

The tumor in accessory parotid gland (APG) is rarely occurred and its incidence is about 7.7% of all parotid gland neoplasms, but has a higher frequency of malignancy than major salivary glands. The mucoepidermoid carcinoma is the most common malignancy in APG, while B-cell lymphoma is less than 2%. It is often appeared as superficial mass in mid-cheek area. This lesion requires differential diagnosis with epidermoid cyst, lipoma, neurogenic tumors, Stensen's duct stone, lymphadenopathy and hemangioma etc. The mucosa associated lymphoid tissue (MALT) lymphoma, which is also termed extra-nodal marginal zone B-cell lymphoma tends to be localized disease for long time and has a relatively indolent course. We recently encountered a 69-year-old man with superficial solitary mass on the right cheek area that finally diagnosed as MALT lymphoma in APG. We report the rare and unique case with brief literature review.

Epstein-Barr virus(EBV) is associated with a wide spectrum of benign and malignant disorders including leukoplakia, Hodgkln's lymphoma, central nervous system lymphoma, peripheral T cell lymphoma and nasopharyngeal undifferentiated carcinoma. There are several distinctive aspects of biology of the virus that are important in investigation of virus in clinical specimens. The abundant expression of the EBER mRNA transcripts makes possible the sensitive detection of latent expression in EBV-associated tumors. Although there has been a dramatic increased interest in the direct characterization of EBV in clinical specimens, there have been few studios about the effective and reliable positive controls in performing in situ hybridization technique for EBV, especially on paraffin-em bedded tissue. We applied Burkitts lymphoma ceil line as positive control in EBV in situ hydridization using Oncor Kit. The cell block of Burkitt lymphoma cell line(CCL85 EB-3) showed strong and specific positivity for EBER in situ in nuclei of EBV infected cells.

Ki-1 lymphoma is a sort of high grade large cell lymphoma and defined on the basis of the reactivity of the tumor cells with monoclonal antibody Ki-1. On fine needle aspiration cytology, the reported case is rare and the differential diagnosis is not easy, especially from undifferentiated carcinoma and Hodgkin's lymphoma. We experienced a case of fine needle aspiration cytology of Ki-1 positive large cell lymphoma in a 61-year old male patient. Fine needle aspiration cytology from the cervical lymph node disclosed hypercellular smears with large single cells on polymorphous lymphoid background. The tumor cells had abundant dense cytoplasm and large nuclei with Irregular profiles. Although most cells were mononuclear binucleated and multilobed/multinucleated cells were also seen Immunohistochemistry was done and revealed strong positive staining for Ki-1 antigen.

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.
