In this report we present a case of disseminated diffuse large B-cell lymphoma (DLBCL) in a 79-year-old man affecting the bone, soft tissue, testis, and both kidneys, which are rarely affected sites. The formation of a large mass in the bone, soft tissue, and testis due to DLBCL is rarely seen nowadays. In this article, we describe the imaging findings and clinical significance of multifocal extranodal involvement in DLBCL, focusing on involvement of bone, soft tissue, and testis.

Background: Lymphoma is a malignant neoplasm of lymphoid tissue classified into Hodgkin's and non- Hodgkin's types. It mostly affects lymph nodes although a considerable proportion of Non-Hodgkin's cases occur in extranodal sites. Materials and Methods: Selected cases diagnosed as non-Hodgkin's lymphoma (NHL) during the period of 1980 to 2012 were retrieved from the archives of the Oral Pathology Diagnostic Laboratory, Faculty of Dentistry, University of Malaya. The sections from the formalin-fixed paraffin embedded tissue blocks were stained with H&E as well as with LCA, CD20, and CD3. Results: The mean age was 41.6 years with a male: female ratio of 1.3:1. Out of the forty two cases, nineteen were Malays, eighteen were Chinese, followed by Indians (3) and Indonesians (2). The most common site of involvement was the mandible (22.2%), followed by the maxilla and palate (19.4% each). Most of the lesions presented as a painless progressive swelling. Only thirty six cases were further subdivided into B or T cell types. The majority were B-cell type (26 cases), of these 6 cases were Burkitt's lymphomas. Only ten cases were T-cell lymphoma, with three cases of NK/T-cell lymphoma. Conclusions: In this series of 42 patients diagnosed as extranodal non-Hodgkin's lymphoma, the lesions appeared as painless swellings, mostly in men with the mandible as the most frequent site of involvement. Majority were B-cell lymphomas with Malays and Chinese being equally affected whereas lymphomas were rare in the Indian ethnicity. T-cell lymphomas were found to be common in the Chinese ethnic group.

Primary lung lymphoma is an uncommon tumor, which constitutes 0.5% of primary lung cancer, and 3% of extranodal lymphoma. The most frequent radiologic presentation of pulmonary parenchymal lymphoma is single mass or nodule. But we have experienced a case which was radiologically presented as patchy lung infiltration at first, and then progressive multiple reticulonodular infiltrations in lung. A 48-year-old woman was admitted to the hospital because of fever and cough. Chest PA obtained on admission revealed multiple patchy infiltration. Eventually, open lung biopsy was performed and the specimen disclosed extranodal NK/T cell lymphoma, and in bone marrow aspiration, hemophagocytosis was present. We report a case of primary extranodal NK/T cell lung lymphoma presented as patchy lung infiltrations, which was treated with chemotherapy.

Nasal-type extranodal natural killer/T-cell lymphoma (ENKTL) is a rare disease presenting with non-specific symptoms, typically originating in the nasal cavity, palate, or midfacial region. Oral cavity is an extremely rare site for this type of lymphoma. In this report, we present a case of palatal perforation and oro-nasal fistula as a manifestation of recurrent ENKTL. Complicated disease entity should be considered when surgeons deal with palatal perforation and oro-nasal fistula.

Primary malignant lymphoma of the lung is a very rare disease, which consists of 0.34% of entire malignant lymphoma. The majority are low-grade B-cell tumors, and because of their morphological peculiarities and overall excellent prognosis, many cases, like many other extranodal lymphomas, have been mislabelled as "pseudolymphomas" in the past. For these reasons their true incidence is difficult to estimate. An incidentally discovered mass in the right middle lobe of a 36-year-old woman was operated on November 9, 2001 at Hanyang University Hospital. A right upper lobectomy was done and the pathologic diagnosis of extranodal marginal zone B-cell lymphoma of MALT type was made.

Objective: To evaluate early treatment for extranodal natural killer/T cell lymphoma (ENK/TCL) in China and provide reference for clinical treatment of these patients. Methods: Computer-based retrieval was performed in PubMed, CNKI, CBM, VIP and WanFang Data to search for randomized controlled trials (RCTs) of treatment for early ENK/TCL, and a meta-analysis was conducted with RevMan 5.0 software. Results: A total of 11 RCTs, including 871 patients, were selected, of which the first radiotherapy had a higher complete response (CR) than the first chemotherapy [OR=14.16, 95%CI (8.68, 23.10), P<0.00001] and CR was not different between combined treatment group and radiotherapy group [OR=1.86, 95%CI (0.47, 3.58), P=0.61], but long-term survival rate was higher with combined treatment[OR=1.88, 95%CI (1.09, 3.19), P=0.02]. No difference in survival rate was observed between radio-chemotherapy and chemo-radiotherapy groups [OR=1.11, 95%CI (0.73, 1.69), P=0.63]. Conclusions: Radiotherapy is of great significance in the treatment of early ENK/TCL, but combined therapy could further enhance long-term survival rate of patients. This conclusion still requires further confirmation using RCTs with high quality and large sample size.

An extranodal marginal zone B-cell lymphoma of the mucosa-associated lymphoid tissue (MALT) is the most frequent type of non-Hodgkin's lymphoma that primarily involves the lung. The radiographical discovery of a pulmonary lesion in an asymptomatic patient is the most common clinical presentation. In general, the prognosis of a localized extranodal pulmonary marginal zone B-cell lymphoma of MALT type is excellent. We report a case of a 61-year-old man who sought evaluation of an incidentally discovered mass in the lung.

Background: The aim of this study was to assess the epidemiological and clinicopathological characteristics of primary extranodal non-Hodgkin's lymphoma (pENL) patients, focusing on treatment and survival outcome. Materials and Methods: Between October 2003 and March 2012, 802 patients with non-Hodgkin's lymphoma (NHL) were diagnosed and treated in two different cancer centers of Southern Turkey. Results: pENL, constituted 12.4% (100/802) of all NHL studied during this period. Median age of the patients was 56 years (range 17-87 years) and the male: female distribution was 3:2. Eighty-five of 100 patients (85%) were in stage I/II, 9/100 (9%) in stage III, whereas 6/100 (6%) were in stage IV. Head and neck constituted the most common site (51/100, 51%), followed by gastrointestinal tract (GIL) (37/100, 37%), and cerebrum (CL) (5/100, 5%). Diffuse large B cell lymphoma (DLBCL) was the most common histological type, observed in 53% of patients, followed by marginal zone extranodal lymphoma (13%). Most of patients (76%) received a CHOP containing regimen. Complete remission (CR) were achieved in 71% of patients. The median follow-up duration of all patients was reported as 37.6 months (range, 0.8-165 months). This period was reported as 137.5 months (range, 117.5-1578.6 months) in gastrointestinal lymphoma (GIL) patients, 119.0 months (range, 91.8-146.1 months) in head and neck lymphoma (HNL) patients, and 18.4 months (range, 12.6-24.1 months) in cerebral lymphoma (CL) patients. Conclusions: Head and neck, and the gastrointestinal tract were the two most common extranodal sites observed. Histologically DLBC accounted for the majority of cases. Most patients were on earlier stages, had low-low intermediate IPI scores and had a favorable prognosis.

A retrospective analysis was done for 69 patients with Stage I and II non-Hodgkin's lymphoma who were treated from May 1981 to December 1990, in the Department of Radiadtion Oncology, Korea University Hospital. We used Ann Arbor Staging system and Working Formulation for histological classification. Forty-three patients (43/69, $62.3{\%}$) were Stage I and 26 patients (26/69, $37.7{\%}$) were Stage II, and B symptom was found in $10.1{\%}$ (7/69). Nodal lymphoma was $21.7{\%}$ (15/69); 14 patients with supradiaphragmatic disease and 1 patient with infradiaphragmatic disease. Extranodal lymphoma was $78.3{\%}$ (54/69): $64.8{\%}$ (35/54) for head and neck, $25.9{\%}$ (14/54) for gastrointestinal tract. Histologically, low grade consists of $8.7{\%}$ (6/69), intermediate grade $84.2{\%}$ (56/69), high grade $10.1{\%}$ (7/69), and diffuse large cell type was the most frequent form with 36 patients (36/69, $52.2{\%}$). Eighteen patients ($26.1{\%}$) were treated with radiation therapy alone,20 patients ($29.0{\%}$) with radiation therapy combined with chemotherapy, 15 patients ($21.7{\%}$) with radiation therapy combined with surgery and chemotherapy, Median survival duration was 28 months, and the range of survival time was from 1 month to 134 months. Overall five-year survival rate for Stage I and II disease was $54.2{\%}$, with $64.5{\%}$ for Stage I and $37.1{\%}$ for Stage II. For nodal lymphoma,5-year survival rate was $45.9{\%}$, and $56.5{\%}$ for extranodal lymphoma; $60.6{\%}$ for head and neck, $52.9{\%}$ for GI tract primary disease. Local control rate for all patients was $88.4{\%}$ (61/69), with $80{\%}$ (12/15) for nodal lymphoma and $90.7{\%}$ (49/54) for extranodal lymphoma. The total failure rate was $34.8{\%}$ (24/69). Five of 24 ($20.8{\%}$) patients who were failed developed local failure only, $12.5{\%}$ (3/24) local failure with distant failure, and distant failure only were found in $66.7{\%}$ (16/24). Between nodal lymphoma and extranodal lymphoma, there was no significant survival difference, but extranodal lymphoma showed higher incidence.
