Adult onset Still's disease (AOSD) is a chronic inflammatory disorder involving multiple systems. The symptoms mimic those of lymphomas, therefore, the diagnosis of lymphoma needs to be excluded prior to establishing the diagnosis of AOSD. Another similar condition is dermatopathic lymphadenopathy (DL). In DL, the histopathological appearance of lymph node biopsy may also mimic AOSD. The DL is associated with several systemic pathologies, such as malignant lymphomas, and rarely AOSD. We present a case of a 43-year-old male presented with 3 months history of fatigue, fever, and lymphadenopathy...

Primary bone lymphoma (PBL) is an uncommon extra nodal disease that represents about 1-3% of lymphoma cases. Imaging findings are variable and non-specific. Computed tomography may demonstrate lytic lesions with sequestra and periosteal reaction. On magnetic resonance imaging, lesions are T1WI hypointense and T2WI hyperintense, related to peritumoral edema or bone marrow replacement. Rarely lesions may have associated fibrosis and show a more hypointense signal pattern on T2WI. After administration of contrast, PBL tends to enhance avidly...

BACKGROUND: It has been proven that epidermal growth factor receptor (EGFR), anaplastic lymphoma kinase (ALK), and KRAS are common driver genes in non-small cell lung cancer (NSCLC). Molecular targeted therapy increases the overall response rate and progression-free survival (PFS) of patients with EGFR-sensitive mutation or echinoderm microtubule-associated protein like 4-anaplastic lymphoma kinase (EML4-ALK) fusion. However, target and targeted drugs for lung squamous cell carcinoma to indicate clinical therapy remain to be confirmed...

Mediastinal grey zone lymphoma, B cell lymphomas with intermediate features between classical Hodgkin lymphoma and primary mediastinal B cell lymphoma, are not well described in the literature. We report the clinical characteristics and outcomes of a large retrospective series of 99 cases centrally reviewed by a panel of hematopathologists, with a consensus established for the diagnosis. Cases were defined as classical Hodgkin lymphoma-like morphology (64.6%) with primary mediastinal B cell lymphoma immunophenotype, primary mediastinal B cell lymphoma-like morphology (30...

INTRODUCTION: Non-Hodgkin lymphoma (NHL) can occur at any site of the body, however diffuse and extensive involvement of the peritoneal cavity occurs rarely. Diffuse large B-cell lymphoma (DLBCL) is one of the dominant histological subtypes in extra nodal lymphoma involving the peritoneal cavity while Burkitt lymphoma is seen less commonly. We report two cases of DLBCL and one case of Burkitt lymphoma presenting with peritoneal lymphomatosis (PL). PRESENTATION OF CASE: A retrospective review of two cases involving DLBCL and one case of Burkitt lymphoma with PL was conducted...

PURPOSE OF REVIEW: The present review summarizes the association of the different histotypes of Epstein-Barr virus (EBV)-associated lymphomas with known genetic lesions and/or oncogenic viruses. A more comprehensive understanding of the complex interplay existing between genetic abnormalities of tumor cells and the viral contribution to the development of EBV-associated lymphomas is pivotal for the development of more effective treatments. RECENT FINDINGS: Recent evidence indicates that HIV may contribute to lymphomagenesis by acting directly on B lymphocytes as a critical microenvironmental factor...

The main purpose of this paper is to provide the information about the incidence and types of pathology of secondary acquired obstructions of the lacrimal excretory outflow system caused by primary lacrimal sac non-neoplastic and neoplastic lesions. After a thorough literature search, 17 case-control studies were found and selected, data were extracted and categorized, to evaluate specific lacrimal sac pathology mimicking inflammation. A total of 3865 histopathologically examined lacrimal sac wall biopsy specimens from 3662 patients, taken during dacryocystorhinostomy for clinically presumed primary chronic dacryocystitis, were analyzed...

Meningiomas are the most common primary nonneuroglial extra-axial neoplasms, which commonly present as spherical or oval masses with a dural attachment. Meningiomas without dural attachment are rare and, according to their locations, are classified into 5 varieties, including intraventricular, deep Sylvain fissure, pineal region, intraparenchymal, or subcortical meningiomas. To the best of our knowledge, intraparenchymal meningioma with cerebriform pattern has never been reported. In this paper, we report a 34-year-old Chinese male patient who presented with paroxysmal headaches and progressive loss of vision for 10 months and blindness for 2 weeks...

Human parvovirus B19 (B19) is harmful during pregnancy since it can be vertically transmitted to the developing fetus. In addition, the anti‑B19 antibodies induced by B19 infection are believed to have a cytopathic role in B19 transmission; however, knowledge regarding the effects of anti‑B19 antibodies during pregnancy is limited. To investigate the possible roles of anti‑B19 antibodies during pregnancy, the present study examined the effects of anti‑B19‑VP1 unique region (VP1u), anti‑B19‑VP2 and anti‑B19‑nonstructural protein 1 (NS1) immunoglobulin G (IgG) antibodies on BeWo trophoblasts...

Chronic hepatitis B infection (CHB) is a known risk factor for malignancy. Unlike hepatocellular carcinoma (HCC), less is known about the risk of non-HCC malignancy. However, epidemiology and pathologic evidence suggests a strong association between non-Hodgkin lymphoma and CHB. Data regarding the risk of other malignancies, such as pancreatic adenocarcinoma and intrahepatic cholangiocarcinoma, are mixed. Surveillance and appropriate treatment of infection and malignancy in these patients is essential. Further study of these associations is needed and may bring new insights in the pathogenesis and treatment of these diseases...

In patients with diffuse large B-cell lymphoma, MYC rearrangement (MYC-R), MYC expression, or concurrent expression of MYC and BCL2 is associated with a poorer prognosis. P53 expression also has been shown to confer inferior survival in diffuse large B-cell lymphoma patients, but less is known about the role of P53 expression in those with MYC-R, MYC expression (MYC+), or MYC&BCL2 co-expression (MYC+/BCL2+). We studied P53 expression in 201 patients with untreated de novo diffuse large B-cell lymphoma. Sixty-seven (33%) cases were P53 positive, 56 (28%) had MYC-R (including 17 MYC/BCL2 double hit lymphoma), 86 (45%) were MYC+/BCL2+, and 47 (24%) were positive for both MYC and P53...

When confronted with a metastatic poorly differentiated tumor of unknown origin, the initial workup includes the standard panel of immunostains to rule out carcinoma, sarcoma, lymphoma, and the greatest mimicker in pathology - malignant melanoma. Although not specific, the S-100 protein is expressed in over 95% of malignant melanomas. Herein, we present a case of multiorgan metastatic malignancy with a dominant hilar and mediastinal mass in a current smoker; clinically, highly suggestive of widespread primary lung cancer...

BACKGROUND Anaplastic large cell lymphoma (ALCL) is a relatively rare subtype of non-Hodgkin's lymphoma (NHL). Like other types of NHL, ALCL primarily involves the nodal area, and sometimes it can involve several extra-nodal sites such as skin, soft tissue, and lungs. However, extensive bone involvement in cases of ALCL is very rare whether it is primary or secondary. Without nodular involvement, ALCL can be misdiagnosed as bone tumor or metastatic carcinoma such as lung, breast, or prostate cancer, which frequently spread to bone...

Subcutaneous panniculitis-like T cell lymphoma (SPTCL) is a rare condition usually considered as favourable. However, it is not known whether polychemotherapy or immunosuppressive-based therapy is the best approach for treating SPTCL. Using data collected between 2000 and 2012 in France, we analysed clinical, biological and pathological data of 27 patients with SPTCL. Medical history revealed that 40% of patients had been previously diagnosed with an autoimmune disorder and 22% with inflammatory panniculitis...
