Non-Hodgkin's lymphoma on the parotid gland is a relatively rare occurrence among head and neck tumors. The mass of parotid gland lymphoma cannot be distinguished from other benign masses of the parotid gland; therefore, it is important to consider lymphoma in the differential diagnosis when examining parotid swellings and masses. Parotid gland lymphoma is most likely to be B-cell, non-Hodgkin's lymphoma of one of three types, which include follicular, marginal zone, and diffuse large B-cell, although other histologic patterns have been described. We present a review of a patient with diffuse large B-cell lymphoma (DLBCL) who presented to the Department of Oral and Maxillofacial Surgery of Pusan National University Hospital (Yangsan, Korea).

Primary spinal cord lymphomas are rare, and are either extra-/intradural masses with leptomeningeal infiltration or intramedullary in nature. The authors present a patient with a diffuse large B-cell lymphoma involving the sacral nerve root, extension to extradural space, and the cranial nerve.

Epstein-Barr virus positive diffuse large B-cell lymphoma is very rare malignant tumor in thyroid gland. Compared to Epstein-Barr virus negative diffuse large B-cell lymphoma, it tends to have more extranodal involvement, does not respond to chemoimmunotherapy well, and has worse prognosis. We have encountered a patient with Epstein-Barr virus positive diffuse large B-cell lymphoma of thyroid gland in 75-year-old female presenting with aggravating dyspnea and neck pain.

This case report that the therapeutic effects of traditional Korean medicine(TKM) treatment on the tumor response in a diffuse large B-cell lymphoma(DLBL) patient. A patient was treated by acupuncture, pharmacopuncture, moxibustion, cupping and herbal medicine once a week at least for 12 months. we evaluated the grade of chief complaints and performed blood tests and sonography, abdominal CT periodically. After 1 month administration with TKM treatment, the symptoms of the patient vanished obviously. the size of inguinal lymphoma decreased gradually through 3 months. then from 3 to 10 months, the size of inguinal lymphoma remained as it is. TKM treatment was maintained continuously. in the abdomino-pelvic CT performed after 12 months, the patient didn't complain any symptom and the size of inguinal lymphoma decreased a little again. This case study supports that TKM treatments may have a efficacy in treating diffuse large B-cell lymphoma(DLBL) patients.

Out of entire salivary tumor, 1.7% are malignant lymphoma developed in salivary gland and it is usually mucosa associated lymphoid tissue (MALT) lymphoma developed in salivary gland. In the case of Non-Hodgkin lymphoma, the most frequently involved extanodal sites of diffuse large B cell lymphoma are bone, skin, thyroid, gastrointestinal tract, and lung. Development in salivary gland is very rare. A 69 years old male patient who have found Lt. submandibular gland (SMG) mass a month ago is suspected of malignancy from his FNA result, so histologic exam by SMG resection was operated. According to histopathologic exam, large B cell lymphocyte infiltratration were generally shown as diffuse and lymphoepitheliallesion were not found. In immunostaining, CD79a showed positive and CD3, CAM5.2 showed negative which diagnosed as diffuse large B cell lymphoma. As Ann Arbor stage I, CEOP-B chemotherapy was used 3 times as treatment without any recurrence. In the case of malignant lymphoma in salivary gland, it develops as painless mass in ipsilateral side. If found in parotid gland, it is rare to have facial nerve falsy and pathologically diagnosed as lymphocytes of abnormal type of monoclonal immunostaining must be provided as evidence. Combined therapy is known as most effective treatment for intermediate grade.

Background: Diffuse large B-cell lymphoma (DLBCL) is the most common form of non-Hodgkins lymphoma (NHL), accounting for approximately 25% of NHL cases. The aim of this study was to evaluate the association between the BCL6 and MUM1 gene expression and patient prognosis and stage. Materials and Methods: After ethical approval, in a cross-sectional study, tissue samples of 80 patients with diffuse large B-cell lymphoma were analyzed for BCL6 and MUM1 gene expression. Immunohistochemical staining was performed with division into categories of 0-5%, 5-25%, 26-50%, 51-75% and more than 75%. Other clinical and histological information such as lymph node involvement, T-stage, B symptoms and patient outcome were also recorded. Data were analyzed with SPSS version 16 and a P-value less than 0.05 was considered significant. Results: The patient mean age was $46.9{\pm}10.5$ years ($47.6{\pm}10.7$ and $46.1{\pm}9.6$ for males and females, respectively). A significant association was seen between lymphoma stage and BCL6 (p=0.045) but not MUM1 expression (p=0.09). However, the latter was associated with mortality (p=0.006) as was also the BCL6 level (p=0.006). Conclusions: : Overexpression of MUM1 and BCL6 is associated with poor prognosis in patients with diffuse large B-cell lymphoma.

Non-Hodgkin's lymphomas are a group of highly diverse malignancies and have a strong tendency to affect organs and tissues that do not ordinarily contain lymphoid cells. Primary extra nodal lymphoma of the hard palate is rare. Here, we present a case of diffuse large B cell lymphoma in a 60-year-old male patient that manifested as slightly painful ulcerated growth on the edentulous right maxillary alveolar ridge extending onto the palate, closely resembling carcinoma of the alveolar ridge. Computed tomography images showed the involvement of the maxillary sinus and right nasal cavity, along with destruction of hard palate, superiorly extending into the orbit. This case report highlights the importance of imaging to evaluate the exact extent of such large malignant lesions, which is essential for treatment planning.

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.

악성 림프종은 림프 세포와 그들의 전구 세포에 광범위한 증식이 발생하는 종양으로 비호지킨 림프종과 호지킨 림프종으로 크게 나뉠 수 있다. 미만성 큰 B세포 림프종은 비호지킨 림프종에 속하는 림프종으로 구강악안면 영역에서 극히 적은 빈도로 발생한다. 또한 이는 비특이적 증상, 예를 들면 안면부 부종, 통증, 발열 및 체중 감소 등을 가지며 따라서 구강악안면 부위의 다른 염증성 및 감염성 질환과 감별 진단이 매우 중요하다.

Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin's lymphoma. Although progressive lymphadenopathy is a typical feature, extranodal involvement may also occur, including the gastrointestinal tract, skin, bone, thyroid, and testes. Central nervous system invasion is rare, so differentiating it from diseases such as inflammatory demyelinating disorder or infection is essential. DLBCL is therefore a challenge to diagnose, especially when the first findings are neurological symptoms. We report an unusual case of DLBCL that presented as transverse myelitis.
