Introduction: Out of a total of 1260 cases of LNH registered at M. Curie Hospital and H. Moore Inst. in Bs As, 563 cases with extranodal localization were reported. This account for 36,74% of the total number. All patients undergo staging procedures, included CT scan of thorax, abdomen, pelvis and bone marrow biopsy. Primary extranodal lymphomas are still a controversial topic. Nodal localizati...

Extranodal natural killer (NK)/T cell lymphoma, nasal type is a condition that has poor prognosis. Accurate diagnosis of lymphoma is made by pathological findings. We report a case of extranodal NK/T cell lymphoma, nasal type affecting the lung and liver and which was difficult to diagnose because of negative biopsy results from multiple sites. A 39-year-old man who had dry cough and fever for ...

Approximately a third of the patients with diffuse large B-cell lymphoma present with extranodal involvement. Our study aims to identify primary extranodal sites of disease associated with prognosis in patients with diffuse large B-cell lymphoma (DLBCL) in the rituximab era. A secondary objective is to describe epidemiological and clinical characteristics of patients with extranodal DLBCL. We i...

Introduction: Diffuse large B-cell lymphoma is the largest subtype of non-Hodgkin’s lymphomas, and is characterized by frequent extranodal presentation. The most common extranodal locations of non-Hodgkin’s lymphomas are: stomach, bone, liver and testis. Simultaneous detection of multiple extranodal involvements during consultation is quite uncommon, and the majority of cases are characterized ...

The gastrointestinal tract is the most common location of extranodal lymphomas and the stomach in particular serves as an excellent model to illustrate many of the general issues concerning extranodal lymphomas. The stomach is the most frequent site of involvement of extranodal gastrointestinal lymphomas with small intestine second in frequency. Large intestinal and rectal lymphomas are less co...

At least one quarter of non-Hodgkin's lymphomas (NHL) arise from tissue other than lymph nodes and even from sites which normally contain no lymphoid tissue. These forms are referred to as primary extranodal lymphomas [1,2]. Since these tumours, numerous when considered together, are widely distributed throughout the body, it is difficult to find adequate series of any given site. Moreover, man...

Background. This study investigated the clinicopathologic significance of extranodal tumor extension in colorectal adenocarcinoma with lymph node metastasis. Method. Included were 419 patients who underwent curative resection for primary colorectal adenocarcinoma. Results. Extranodal tumor extension was observed more frequently in tumors with ulceroinfiltrative gross type (p = 0.026), higher hi...

Extranodal NK/T-cell lymphoma, nasal type, is an aggressive EBV-associated lymphoma that mainly involves the nasal cavity but has also been reported to involve other extranodal sites without nasal involvement. In contrast to aggressive NK cell leukemia (a marrow-based aggressive leukemia of NK-cell origin); extensive bone marrow and blood involvement is extremely uncommon by nasal type NK/T lym...

Introduction: Extranodal Natural Killer (NK)/T-cell lymphoma (NKTCL) nasal type is a rare but well-known disease with poor prognosis. NKTCL is more prevalent in Asia and comprises about 7-10% of all non-Hodgkin lymphoma cases in this region. The characteristic clinical pattern of NKTCL is the destruction of the midline structures of the mid-face. Case Report: The present study examines a case o...

OBJECTIVE The aim of this study was to identify clinicopathological variables associated with the clinical outcomes of patients with lymph node metastasis-positive urothelial bladder carcinoma after radical cystectomy. METHODS Forty-six patients who underwent radical cystectomy without preoperative chemotherapy and had histologically proven nodal metastasis were included in the study. The sta...
