Primary hepatic lymphoma is a rare disorder representing less than 1% of all extranodal lymphomas. Histological examination of a primary hepatic lymphoma usually reveals a diffuse large B-cell lymphoma; there have been few reports of primary hepatic mucosa-associated lymphoid tissue (MALT) lymphomas. A 67-year-old man was being treated for a duodenal ulcer; while receiving therapy for the ulcer...

In the appropriate clinical setting, certain aspects of extranodal abdominal lymphoma, as revealed by current cross-sectional imaging techniques, should be considered potentially diagnostic and can hasten the diagnosis. In addition, diagnostic imaging in the context of biopsy-proven lymphoma can accurately stage the disease for its appropriate treatment. The purpose of this article was to illus...

We report a case of a 75-year old man that came at hematologist’s attention for lymphoma evaluation due to axillary lymph node enlargement and fever. Thorax, abdomen and pelvis Contrast-Enhanced Computed Tomography (CECT) showed lymph nodes, spleen and liver lesions. Axillary lymph node biopsy was performed and the diagnosis of marginal zone lymphoma (MZL) at stage IV was postulated, then the p...

The group of marginal zone B-cell lymphomas (MZL) comprises three different entities, extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (currently called MALT lymphoma), nodal marginal zone B-cell lymphoma (previously known as monocytoid lymphoma), and splenic marginal zone B-cell lymphoma (with or without circulating villous lymphocytes).[1-3] Primary splenic and no...

Extranodal NK/T cell lymphoma is an uncommon malignancy usually involving the sinonasal area. We report an unusual case of extranodal NK/T cell lymphoma diagnosed in a 62-year-old Caucasian male who died of progressive cardiorespiratory failure but had no clinically detectable upper respiratory system lesions. The initial diagnosis was made cytologically on a sample of pericardial fluid that co...

Primary testicular lymphoma (PTL) is a rare form of extranodal lymphoma, this neoplasm the most common malignant tumor testis in elderly age, and majority cases are histologically diffuse large B-cell (DLBCL), accounting for 80% to 98% non-hodgkin lymphoma. Patients with primary DLBCL show continuously high risk recurrence no plateau survival curves tendency involve other sites, especially cent...

BACKGROUND Extranodal natural killer (NK)/T-cell lymphoma is a subtype of lymphoma that is derived from NK cells. It is considered as an aggressive form of non-Hodgkin's lymphoma because of frequent relapses and resistance to treatment. Relapsed NK/T-cell lymphoma often follows a fulminant course that is refractory to conventional chemotherapy treatment. METHODS Several patients with extranod...

Primary lymphoma of the bladder is extremely rare. It represents less than 0.2% of all extranodal primary lymphomas and is usually extranodal marginal-zone B cell lymphoma of mucosaassociated lymphoid tissue (MALT).1 We herein report a case of primary MALT lymphoma of the bladder in a 77-year-old female patient who was successfully treated with radiotherapy. This lymphomawas not diagnosed earli...

Mature Tor natural killer (NK)/T-cell lymphoma makes up only 5% to 18% of all cases of non-Hodgkin lymphoma (NHL). The relative frequency and optimal therapy for these disorders is not well defined. Extra nodal NK/T-cell lymphoma is a distinct entity in the World Health Organization (WHO) classification [1]. It is more prevalent in Asians and Native Americans, occurs most often in adults, and a...
