INTRODUCTION Non-Hodgkin's lymphomas (NHL) in China appear to have many characteristics different from those Western countries, but clinical studies to provide details have been rare so far. METHODS This study retrospectively analyzed the characteristics of clinical and pathological data for the 1248 NHL patients in the Shandong region of China between 2002 and 2010. RESULTS From 2002 to 20...

BACKGROUND/AIMS Although the incidence of T-cell non-Hodgkin's lymphoma (NHL) is higher in Far East Asia than in Western countries, its incidence and clinical course in Korea are not well-defined. Therefore, we assessed the relative frequency and clinical features of T-cell NHL in Korea. METHODS We performed a retrospetcive analysis of 586 patients with NHL. RESULTS 101 (17.2%) had T-cell N...

Primary gastric lymphoma (PGL) is the most common type of extranodal that originates from lymphatic tissue within submucosa. In past two decades, treatment PGL has been overturned surgery to non-surgical individualized treatment, and its prognosis are different those other malignant lesions in stomach, so early diagnosis, accurate staging, timely monitoring outcome extremely important. Unlike i...

BACKGROUND Mucosa-associated lymphoid tissue (MALT) lymphoma is among the most common forms of extranodal lymphomas, but little is known about subcutaneous involvement in patients with non-primary cutaneous marginal zone lymphomas. DESIGN AND METHODS Patients with MALT lymphoma diagnosed and treated at our institution between 1999 and 2010 were analyzed for subcutaneous deposits from MALT lym...

EBV-positive diffuse large B-cell lymphoma of the elderly is a newly described aggressive lymphoma predominantly affecting patients >50 years of age. Patients may present with nodal and/or extranodal involvement. The lung is one of the more common extranodal sites. The incidence of pleural fluid involvement is less well described. In one study by Oyama et al., pleural effusions were noted in ni...

The World Health Organization (WHO) classification recognizes 2 main categories of natural killer (NK) cell-derived neoplasms, namely, extranodal NK/T-cell lymphoma, nasal type, and aggressive NK-cell leukaemia. Extranodal nasal NK/T-cell lymphoma is more frequent in the Far East and Latin America. Histopathological and immunophenotypical hallmarks include angiocentricity, angiodestruction, exp...

Diffuse large B-cell lymphoma is extranodal in approximately 40% of cases, arising in nearly any organ system. DLBCL involvement of soft tissue and in particular skeletal muscle is extremely rare, comprising less than 1% of all extranodal non-Hodgkin lymphomas (NHL). We report a case of a 79-year-old man that presented with a DLBCL of the left triceps. In particular, we describe an unusual hist...

Peripheral T-cell lymphomas are a group of heterogeneous disorders and according to WHO classification, are categorized into nodal and extranodal forms. NK/T-cell lymphoma, nasal type, is a subtype of extranodal peripheral T-cell lymphoma and commonly presents as a midfacial destructive lesion. This disorder is more prevalent in Asia and South America and has a strong association with Epstein B...

Lymphoma which has a wide range of manifestations is the third malignancy in pediatrics. Nearly, 50% of patients have extranodal involvement. Pancreas can be affected secondarily more than primarily. A 10-year-old boy with recurrent abdominal pain in the epigastric region for six weeks was referred to Amirkola Childrenchr('39')s Hospital, affiliated to Babol University of medical sciences (nort...

Mucosa-associated lymphoid tissue (MALT) lymphoma has drawn attention in the last twenty years due to its pathological and clinical characteristics. It is a question of B-cell neoplasm with extranodal origin, and with invariable prolonged localisation, indicating indolent malignancy. It is believed that this type of lymphoproliferative neoplasm is triggered by chronic antigenic stimulation. Thi...
