Polymorphisms of inflammation-related genes have been found to be associated with non-Hodgkin lymphoma (NHL) or some of its subtypes, but only a few relevant data have been reported in China. In this study, the Snapshot method was used to assess genetic variation; a total of 14 single nucleotide polymorphisms (SNPs) for 6 inflammatory factors in 157 NHL cases (64 Uygur ethnic subjects, 93 Han Chinese) and 435 controls (231 Uygur and 204 Han Chinese) were studied from the Xinjiang province of China. Haplotype distribution was estimated using PHASE 2.3 software. Statistical differences in the genotype and haplotype frequencies between case and control groups were also considered and estimated. For the Han population, the geneotype distributions for TNF-${\alpha}rs1800629$, TNF-${\alpha}rs1800630$, IL-6 rs1800795, IL-6 rs1800797, NF-KB1 rs1585215 and TLR-4 rs4986790 showed significant differences between the case and control groups (p<0.05). The TNF-${\alpha}$ gene frequencies of ACG and CCA haplotypes in the cases were higher than in the controls (OR=2.45, 95% CI: 1.55-3.89, p=0.0002, OR=2.53, 95% CI: 1.10-5.80, p=0.029, respectively), and the same findings were detected for TNF-${\beta}$ gene CA haplotype (OR=1.87, 95% CI: 1.21-2.90, p=0.0054). However, for the Uygur population, no such significant differences were detected within the gene-type distribution of the 14 SNPs. The TNF-${\alpha}$ gene frequency of the CCA haplotype between the two groups (OR=1.98, 95% CI: 1.11-3.51, p=0.021) revealed a statistically significant difference. Our results showed that polymorphic variations of inflammation-related genes could be important to the NHL etiology of the Han population, and that these may only have limited influence on the Uygur population.

Lymphomas of the nasal sinuses are relatively uncommon and represent less than 1% of all head and neck malignancies. Most common symptoms are nasal obstruction, epistaxis, rhinorrhea. We report a case of primary extranodal diffuse large B-cell non-Hodgkin's lymphoma in nasal sinuses accompanying with exophthalmos. A 70-year-old male patient was referred to our hospital with exophthalmos and severe septal deviation. We conducted endoscopic biopsy with septoplasty and biopsy result was diffuse large B-cell lymphoma. He received chemotherapy(R-CHOP) and radiotherapy. At follow-up, he remained free of disease.

Purpose: Although each Waldeyer's ring sub-site is considered an independent prognostic factor, few studies have assessed the prognosis and treatment of tonsillar lymphoma. Treatment outcomes were analyzed in patients with primary tonsillar lymphoma who were treated with chemotherapy and radiotherapy (RT). Materials and Methods: Nineteen patients with diffuse large B-cell lymphoma were evaluated, with a median follow-up of 53 months. Age, sex, and histology, amongst other factors, were reviewed. Progression-free survival (PFS) and overall survival (OS) rates were analyzed. Results: Most patients had Ann Arbor stage I-II (94.7%), IPI score of 0 (89.5%), and complete remission after chemotherapy (89.5%). The 5-year PFS and OS rates were 74.6% and 80%, respectively. In univariate analysis, the rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) regimen resulted in a better PFS than the cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) regimen (88.9% vs. 50.0%; p = 0.053). RT dose was related to the survival outcome (p = 0.010 for PFS, p = 0.044 for OS). Patients were classified into the CHOP + RT (>40 Gy) group and R-CHOP + RT (${\leq}40Gy$) group. The 5-year PFS rates were 50% in the CHOP + RT group, and 100 % in the R-CHOP + RT group (p = 0.018). The 5-year OS rates were 66.7% and 100%, respectively (p = 0.087). Conclusion: Primary tonsillar lymphoma patients typically have favorable outcomes. Chemotherapy (R-CHOP) combined with relatively lower dose consolidative RT may be safe and effective for primary tonsillar lymphoma.

Primary nasal type natural killer (NK)/T cell (NKTC) lymphoma, a specific form of malignant lymphoma, has a higher geographic incidence in Oriental, Mexican, and South American populations than the Western population. In Koreans, it comprises 9-12% of all cases of non-Hodgkin's lymphoma. This type of lymphoma has also been named as angiocentic lymphoma and lethal midline granuloma because the most common site is the upper airway area and its clinical aggressiveness presents with a necrotic and destructive pattern. NKTC lymphoma can also be detected in different organs (testis, spleen, parotid gland, skin, gastroinstinal tract, central nervous system, lungs, bone marrow, etc.) other than the upper airway including the oral cavity. The lymphoma detected in the oral cavity shows various destructive and inflammatory changes, similar to the signs of inflammation and infection from periodontitis and pulpal disease, making a diagnosis difficult with just the clinical signs. For early detection, clinical, radiological, and pathological examinations are required. This report describes the clinical, radiological and histological characteristics with a case report for the early detection of NKTC lymphoma in the oral cavity.

Background: This study aimed to characterize the histopathological pattern of lymph node pathology among Saudi patients and to highlight the age and gender variations of these lesions as base line data. Materials and Methods: We retrospectively analyzed the data from lymph node biopsy specimens received at the Department of Pathology, King Fahad Hospital, Madinah, Saudi Arabia from January 2006 to December 2013. Results: Of the 289 lymph node biopsy specimens received, 154 (53.3%) were from males and 135 (46.7%) from females giving a male: female ratio of 1.14:1. Age of the patients ranged from 2.5 to 96 years with a mean age 33.9 years. The commonest lymph node group affected was the cervical (30.4%) followed by axillary (9.7%) and inguinal (8.7%). Malignant lymphoma [71 Hodgkin's disease (HD), 57 non Hodgkin's lymphoma (NHL)] 128 (44.3%), reactive hyperplasia 68 (23.5%), and tuberculosis 41 (14.2%) were the common causes of lymph node enlargement. While HD, reactive hyperplasia and tuberculosis were commonest in young adult patients (10-29 years old) and rare above the age of 50 years; NHL was the predominant cause of lymph node enlargement above 50 years. Conclusions: Lymph node biopsy plays an important role in establishing the cause of lymphadenopathy. Among the biopsied nodes, lymphomas were the most common (44.3%) followed by non-specific reactive hyperplasia (23.5%) and tuberculous lymphadenitis (14.2%).

Primary lymphoid tumors of orbit are rare. Sometimes they pose difficulty in differentiating malignant non-Hodgkin's lymphoma of the orbit from benign lymphoid hyperplasia or pseudotumor of the orbit by growth characteristics and histologic examination of a biopsy specimen. Consequently, systemic work-up for staging of the disease before the initiation of treatment is essential. All lymphoid tumors of the orbit are radiosensitive and the response to radiotherapy is rapid and complete. Radiation dose for permanent control varies from 2,400 to 4,500rads in $2.5\~4$ weeks depending on extent and location of the disease. A case of localized lymphoma of the orbit was treated with radiotherapy. For the following 15 months, the patient was clinically free of disease without any evidence of side effects of radiation treatment.

Breast lymphomas are rare, malignant breast neoplasms with a heterogeneous pattern of clinical symptoms. Burkitt's lymphoma is a rare, highly aggressive, and rapidly growing B-cell non-Hodgkin lymphoma. We report about a 27-year-old woman diagnosed as having secondary breast Burkitt's lymphoma, probably originating from the stomach, with multiple distant metastases. Breast ultrasonography revealed multiple, variable sized, heterogeneous masses with posterior acoustic enhancement and echogenic rims. These imaging findings may sometimes overlap with those of other breast malignancies. However, unlike other breast malignancies, lymphoma can be diagnosed by biopsy and does not require surgical excision. To avoid unnecessary treatment, radiologists and clinicians should be aware of the characteristic imaging features of breast lymphomas.

Purpose: Extranodal marginal zone B cell lymphoma of MALT type represents approximately 8% of non-Hodgkin's lymphomas and this lymphoma is present in extranodal sites. Although the presentation of this lymphomain in stomach is usually associated with H. pylori infection in 95% of cases, MALT lymphoma found in soft tissue has been reported very rarely in the field of plastic surgery. We report a case of MALT lymphoma in the submandibular gland without any involvement of other organs such as the stomach. Methods: A 49-year-old man complained of a huge neck mass sized about $10{\times}12cm$. It started about 2 years ago and grew rapidly for the late 6 months. It was of hard nature with erythematous skin overlying it. Under the diagnosis of possible malignant lymphoma or sarcoma, radical resection was performed and the defect was reconstructed using transverse rectus abdominis musculocutaneous free flap. Results: The mass was well demarcated from the normal tissue, $11{\times}10.5{\times}10cm$ in size and whitish-gray color. Immunohistochemical analysis demonstrated that the tumor cells were LCA(+), CD20(+), CD3(-) and CD5(-). The tumor was diagnosed as extranodal marginal zone B cell lymphoma. The patient was treated with prophylactic radiation therapy after surgery, there was no complication for 1 year. Conclusion: We reported that very rare form of MALT lymphoma in 49-year-old male patient was experienced with clinical characteristics, histologic features and references.

Mantle cell lymphoma (MCL) is a rare subtype of B-cell neoplasm and it accounts for about 3~6% of all non-Hodgkin's lymphomas. It occurs mainly in middle-aged or elderly man, involving the extra-nodal sites such as gastrointestinal tract, bone marrow and Waldeyer's ring. The incidence of the MCL in salivary gland is about 3%. The blastoid MCL is a rare variant and it has a very aggressive clinical course. It is extremely rare to be arising from the parotid gland. To our knowledge, similar case has not been reported in domestic literature, one case has been described in English literature. We experienced a rare and unique disease entity and report it with brief literature review.

Radiotherapy result of 162 patients with stage I, II intermediate grade non-Hodgkin's Iymphoma was analyzed to clarify the role and limit of radiotherapy. Of 68 initial failures, 38.2% occurred in field and 61.8% occurred out of field. Proportion of in-field and out-of-field failures in stage I was 30.0% and 70.0%, respectively with involved field treatment and was 43.8% and 56.2% with extended field treatment, respectively; in stage ll , was 16.7% and 83.3%, 41.7% and 58.3%, respectively. The disease free suwival rate at S years was 48.1% for all patients and was 50.3% and 40.4% for patients with stage I and II, respectively. The survival was significantly different by stage. Bulky tumors (${\geq}10$ cm) and B symptoms didn't influence prognosis significantly. The 5 year disease free suwival with extended or wide field was better than that with involved field especially in stage I. Overall survival rates for all patients, patients with stage 1, and ll disease were 57.7%, 65.3% and 52.2% , respectively, after survival gain of the salvage chemotherapy was combined. But the overall survival of stage I disease was not better than that of stage II disease. Thus, extended field was required to achieve better disease free survival and relapsed cases might gain with chemotherapy.
