Involvement of the musculoskeletal system by primary or metastatic malignant neoplasms mimicking common orthopaedic conditions is well recognized. The diagnosis may be delayed in the absence of radiographic abnormalities. Twenty-five percent of lymphoma cases have skeletal involvement, and they can affect both bone and soft tissue. Lymphoma is sometimes discovered by means of routine histologic examination of tissue collected at the time of orthopaedic surgery. To the best of our knowledge, this is the first report of lymphoma occurring at the site of prior shoulder surgery and mimicking an infection...

Tumors of the pediatric facial skeleton represent a major challenge in clinical practice because they can lead to functional impairment, facial deformation, and long-term disfigurement. Their treatment often requires a multidisciplinary approach, and radiologists play a pivotal role in the diagnosis and management of these lesions. Although rare, pediatric tumors arising in the facial bones comprise a wide spectrum of benign and malignant lesions of osteogenic, fibrogenic, hematopoietic, neurogenic, or epithelial origin...

Non-Hodgkin lymphoma (NHL) frequently manifests in extranodal structures in the chest, often in the form of secondary involvement but occasionally as primary disease. Because staging and treatment are affected by the presence of extranodal disease at imaging, radiologists' interpretation and management of suspicious findings are critical to patient care. Unfortunately, owing to considerable imaging overlap with other diseases, primary extranodal lymphoma is difficult to diagnose with imaging alone. Radiologists should have a heightened degree of suspicion in patients at risk (including patients with immune compromise, autoimmune diseases, or a history of stem cell or solid organ transplant) or with particular imaging appearances (including the vertebral wraparound sign, nonresolving consolidation, an infiltrative soft-tissue mass, and lesions demonstrating vascular encasement without invasion)...

Chronic myeloid leukemia (CML) is characterized by increased and unregulated proliferation of granulocytic lineage in the bone marrow and presence of these immature myeloid cells in the peripheral blood with presence of Philadelphia (Ph) chromosome. Tyrosine kinase inhibitors are the most important drugs in the CML therapy and provide long disease-free survival. Due to the increased survival of CML patients with continual administration of these drugs, the chance of development of secondary malignancies may increase...

A 47-year-old woman presented with symptoms of sharp pain over the left anterior thigh with radiation from the groin to the knee. She subsequently developed numbness in that region and reduced motor strength in extensors of the left knee. Plain radiography of the spine and knee was normal. An MRI of the spine revealed an irregular extramedullary mass with intradural and extradural components, extending from the L3 to L5 vertebrae. She underwent a laminectomy and posterior spinal decompression based on a working diagnosis of nerve sheath tumour...

PURPOSE: Primary bone lymphoma (PBL) is one of the rarest primary bone malignancies. Very limited data are available on the role of fluorine-18-fluorodeoxyglucose (F-FDG) PET/CT in PBL. PATIENTS AND METHODS: Overall, 16 relevant patients had F-FDG PET/CT for staging or staging/restaging PBL. The cases with extraskeletal lesions such as lymphadenopathy or with osseous involvements in disseminated lymphoma were excluded on the basis of the definition of PBL. F-FDG PET/CT findings were correlated to pathologic and/or anatomic image information...

Follicular lymphoma (FL) is the most frequent indolent lymphoma and is characterized by the accumulation of germinal center-derived malignant B cells engaged in a bidirectional crosstalk with their supportive microenvironment in invaded lymph nodes (LN) and bone marrow (BM). T follicular helper cells (TFH) and infiltrating stromal cells have been shown to favor FL B-cell growth but the mechanisms of their protumoral effect and how LN/BM microenvironment is converted into a lymphoma-permissive cell niche remain poorly understood...

Primary bone lymphoma and primary adrenal lymphoma are rare clinicopathological entities of non-Hodgkin's lymphoma (NHL). We present the first case of diffuse large B-cell lymphoma with the involvement of a single bone and both adrenal glands alone with adrenal insufficiency. As primary extranodal NHL may have other unusual extranodal lesions, which may present unexplained clinical findings, patients with primary extranodal NHL require careful systemic examination, even when lymphadenopathy is absent.

Primary effusion lymphoma (PEL) is a rare type of non-Hodgkin's lymphoma presenting as a lymphomatous effusion and absence of a solid tumor mass. Extracavitary PEL (EC-PEL) is a subtype of PEL with the absence of an effusion but presence of solid tumor. PEL and EC-PEL share the same histopathologic and immunophenotypic features. Kaposi sarcoma-associated herpesvirus (KSHV) positivity is seen universally in these malignancies and is a requisite for diagnosis. Most cases are seen to occur in HIV positive individuals...

The v-rel oncoprotein encoded by reticuloendotheliosis virus T strain (Rev-T) is a member of the rel/NF-κB family of transcription factors capable of transformation of primary chicken spleen and bone marrow cells. Rapid transformation of avian haematopoietic cells by v-rel occurs through a process of deregulation of multiple protein-encoding genes through its direct effect on their promoters. More recently, upregulation of oncogenic miR-155 and its precursor pre-miR-155 were demonstrated in Rev-T-infected chicken embryo fibroblast cultures as well as Rev-T-induced B-cell lymphomas...

B-Cell CLL/Lymphoma 6 (BCL6) is a proto-oncogene that is highly expressed in acute lymphoblastic leukemia (ALL). BTB and CNC Homology 1 Basic Leucine Zipper Transcription Factor 2 (BACH2) is a suppressor of transcription. The BACH2-BCL6 balance controls selection at the pre-B cell receptor checkpoint by regulating p53 expression. However, the underlying mechanism and the clinical relevance of the BCL6/BACH2 axis are unknown. Here, we found that Ikaros, a tumor suppressor encoded by IKZF1, directly binds to both the BCL6 and BACH2 promoters where it suppresses BCL6 and promotes BACH2 expression in B-cell ALL (B-ALL) cells...

Myeloid, plasma cell, and lymphoblastic neoplasms are expected findings in bone marrow but are much less commonly diagnosed as primary processes in lymph nodes. The objective of this review is to aid pathologists in recognizing common hematopoietic neoplasms in the unusual setting of initial presentation in lymph nodes. Review of historical background and evolution of testing strategies is presented in order to improve understanding of the need for accurate diagnosis and classification using current nomenclature...

Burkitt's Lymphoma (BL) has three peaks of occurrence, in children, adults and elderly, at 10, 40 and 70 years respectively. To the best of our knowledge, no study has been conducted to assess predictors of survival in the three age groups. We hypothesized that survival predictors may differ by age group. We, therefore, sought to determine survival predictors for BL in these three groups: children (<15 years of age), adults (40-70 years of age) and elderly (>70 years of age). Using the Surveillance, Epidemiology, and End Results (SEER) database covering the years 2000-2013, we identified 797 children, 1,994 adults and 757 elderly patients newly diagnosed with BL...
