non-hodgkin lymphoma usually presents with generalized lymphadenopathy, but it can also involve any part of the human body. lymphomatous involvement of muscles is a rare presentation and has been reported to occur in only 1.1% in non-hodgkin lymphoma. here we, present a 32 year-old iranian man with primary involvement of spleen, bone, bone marrow and muscle, mimicking soft tissue sarcoma; core ...

objective(s): the aim of this study is to evaluate the role of pet-ct in identification of different patterns of extranodal involvement in hodgkin’s disease (hd) and non-hodgkin’s lymphoma (nhl) and to enlist the common sites of extranodal involvement in each histological type and compare our results with the existing literature. methods: in this retrospective study of 281 cases of lymphomas of...

lymphomas are solid malignant tumors having a wide spectrum of clinical and pathological features. non-hodgkin’s lymphoma (nhl) is a subtype of lymphoma with two-thirds of the cases presenting as lymph node enlargement. the remaining one third of nhl cases has been reported in the extranodal sites, including the gastro intestinal tract, waldeyer’s ring, bone, skin, and brain. intraoral non-hodg...

Classification and proper treatment of extranodal lymphoma is hindered by the diversity of lymphoma types and the relative rarity of many of these tumour types. In order to review controversial issues in extranodal lymphoma diagnosis, a joint Workshop of the European Haematopathology Association (EAHP) and the Society for Hematopathology (SH) was held, where 99 selected cases were reviewed and ...

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...

Malignant lymphomas represent approximately 5% of all malignant neoplasms of the head and neck and may involve nodal or extranodal sites. Nodal head and neck lymphomas are similar to other nodal sites and are not further reviewed here. The head and neck region is the second most frequent anatomical site of extranodal lymphomas (after the gastrointestinal tract). Most are non-Hodgkin's lymphomas...

Extranodal NK/T-cell lymphoma is closely associated with Epstein-Barr virus (EBV) infection. However, the prognostic value of EBV-DNA in extranodal NK/T-cell lymphoma remains unclear. Thus, we conducted a meta-analysis to estimate its prognostic significance. PubMed, EMBASE, and Web of Science were used to search for studies conducted until June 12, 2017. The pooled hazard ratio (HR) and its 95...

Lymphoma may originate in extranodal sites. Extranodal lymphoma may also be secondary to and accompany nodal disease. Fluorine-18 fluorodeoxyglucose (18F-FDG) imaging has an essential role in the staging of lymphoma, in monitoring the response to therapy, and in detection of recurrence. The introduction of 18F-FDG PET/CT hybrid imaging allows for accurate localization of disease and may be spec...

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...
