Platelets are megakaryocyte-derived nuclear-free fragments that participate in cardiovascular diseases including acute myocardial infarction, ischemic stroke, hypertension, and atherosclerosis. At the endothelium damage site, platelets interact with sub-endothelial matrix proteins such as glycoprotein VI/Fc receptor γ-chain (GPVI/FcRγ), G protein-coupled receptor/phospholipase Cγ(β) (GPCR/PLCγ(β)), Rho/RhoK and integrin. The activation of these signaling pathways triggers intracellular calcium increase and causes platelet adhesion, aggregation, granule release and finally thrombus formation...

BACKGROUND: In patients presenting with rapidly progressive dementia, prion disease may enter the differential diagnosis. The commonest malignancies masquerading as prion disease are primary CNS lymphoma and intravascular large B-cell lymphoma, both rare and difficult to diagnose without brain biopsy. CASE PRESENTATION: This 82-year-old lady with a past history of hypertension, presented with rapidly progressive cognitive impairment and ataxia. The possibility of sCJD was raised...

An increased risk of arteriosclerosis has been noted in cancer survivors. Currently, there are only a few reports available that consider the risk of arteriosclerosis in patients treated with chemotherapy. Patients with an advanced stage B-cell malignant lymphoma are typically treated with a combination therapy of rituximab and cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP). Complications such as diabetes mellitus (DM), hyperlipidemia (HL), and osteoporosis due to prednisolone and cardiotoxicity due to anthracyclines are well known...

BACKGROUND Follicular B cell lymphomas account for a significant portion of all newly diagnosed non-Hodgkin's lymphomas. While involvement can be varied, the most common extranodal presentation is within the gastrointestinal tract beyond the stomach. In addition, the stomach has a diffuse multivessel vascular supply, which decreases the likelihood of developing ischemic gastritis. CASE REPORT An 89-year-old woman with history of diabetes, deep venous thromboembolism, and hypertension was referred due to a newly diagnosed retroperitoneal mass...

We report on a 59-year-old woman who presented with nausea, fatigue, arterial hypertension, and acute renal failure. Clinical examination, laboratory findings of blood and urine and abdominal sonography were inconclusive. Renal biopsy revealed infiltration by a diffuse large B‑cell lymphoma. In fluorodeoxyglucose positron emission tomography/computed tomography tracer enrichment was demonstrated in both kidneys, skeletal system and retroperitoneal lymph nodes. Renal function improved already after the first cycle of R‑CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone)...

The authors describe an immunocompetent, 50-year-old man who complained of a daily transient blurring of his vision with bilateral papilloedema. His visual acuity was 20/20 OU, and the blind spot was enlarged bilaterally. There was intracranial hypertension, but imaging for systemic and brain tumours were negative. These findings suggested a diagnosis of the pseudotumor syndrome. However, MRI showed leptomeningeal enhancement, and acetazolamide successfully resolved his visual symptoms and papilloedema. Cytology and flow cytometry of the CSF led to the final diagnosis of primary leptomeningeal lymphoma (PLML)...

WHAT IS KNOWN AND OBJECTIVE: Chylous ascites is a rare condition. The most frequent causes are lymphomas, solid malignancies, abdominal trauma and cirrhosis. Isolated case reports describe the relationship between calcium channel blockers (CCB) and chyloperitoneum. Lercanidipine is a third-generation dihydropyridine with low rate of adverse events. We describe a case of lercanidipine-induced chylous ascites. CASE SUMMARY: An 80-year-old white female with hypertension treated with lercanidipine, developed chylous ascites and abdominal pain after the dosage of the CCB was doubled...

Severe mycoplasma pneumonia is a rare entity with only 0.5-2% of cases having a fulminant course. We present a 74-year-old woman with hypertension, diabetes mellitus and remote history of marginal zone B-cell lymphoma admitted with abdominal pain and diarrhea of 1-2 days associated with body-aches, dyspnea, dry cough and weight loss for 2-3 weeks. On physical exam, she was febrile, tachypneic, tachycardic and hypoxic on room air. Chest examination revealed diffuse crackles and end-expiratory wheezes. Laboratory tests showed anemia, acute-on-chronic kidney injury and hyaline casts and epithelial cells in the urine analysis...

Myeloid sarcoma is an extramedullary collection of blasts of the myeloid series that partially or totally effaces the architecture of the tissue in which it is found. These tumors have been described in many sites of the body, but the skin, lymph nodes, gastrointestinal tract, bone, soft tissue, and testes are most common. They can arise in a patient following the diagnosis of acute myeloid leukemia, but they may also be precursors of leukemia and should be considered diagnostic for acute myeloid leukemia. The differential diagnosis of this neoplasm includes malignant lymphoma, with which it is often mistaken, leading to diagnostic and therapeutic delays...

Giardia lamblia (G. lamblia)-filled pancreatic masses are a rarely reported entity. Furthermore, there are only a few case reports in literature on the association of these masses with cancer. We present a case of a G. lamblia-filled pancreatic cystic mass in a patient with a history of T-cell-rich B-cell lymphoma. The authors performed a PubMed search using (Medical Subject Headings) MeSH terms of pancreas, mass, Giardia, and lymphoma.  A 53-year-old male with past medical and surgical history of T-cell-rich B-cell lymphoma, status post R-CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone plus rituximab) therapy with positron emission tomography (PET) scan showing no residual disease, essential hypertension, and alcohol use disorder presented to the emergency department (ED) with epigastric pain and nausea for one week...

Kidney involvement is an under-recognized complication of non-Hodgkin lymphomas. They occur in a variety of mechanisms and differ widely in their clinical presentation. We take this opportunity to report a case of a 65 year-old man who developed a rapidly progressive glomerulonephritis within days after completing his first cycle of R-CHOP (Rituximab, Cyclophosphamide, Doxorubicin, Vincristine, Prednisolone) chemotherapy for newly diagnosed mantle cell lymphoma. He was odematous, hypertensive, oliguric with nephrotic range proteinuria and an active urine sediment...

Heritable pulmonary arterial hypertension (HPAH) is an autosomal dominantly inherited disease caused by mutations in the bone morphogenic protein receptor 2 (BMPR2) gene and/or genes of its signalling pathway in approximately 85% of patients. We clinically and genetically analysed an HPAH family without mutations in previously described pulmonary arterial hypertension (PAH) genes. Clinical assessment included electrocardiogram, lung function, blood gas analysis, chest X-ray, laboratory testing, echocardiography and right heart catheterization in case of suspected disease...

BACKGROUND: The risk of non-Hodgkin lymphoma is increased 200-fold in individuals seropositive for human immunodeficiency virus compared to those free from human immunodeficiency virus. Human immunodeficiency virus-associated non-Hodgkin lymphoma is known for its atypical presentation, aggressive ability, widespread involvement, poor response to chemotherapy, and high relapse potential which makes both the diagnosis and management a difficult undertaking especially in resource-poor settings...

In the absence of a driver mutation, chemotherapy is the standard treatment option as first- and second-line therapy for advanced non-small-cell lung cancer (NSCLC). Though a large number of patients are suitable for post second-line therapies, the quality and quantity of the available drugs in this setting is poor. Apatinib, a small molecule vascular endothelial growth factor receptor-2 (VEGFR-2) tyrosine kinase inhibitor, is a first-generation oral antiangiogenesis drug approved in the People's Republic of China for use as a subsequent line of treatment for advanced gastric cancer...

Cutaneous T-cell lymphomas (CTCL), especially mycosis fungoides, can be considered as a state of longstanding low-grade systemic inflammation. Many studies have focused on secondary cancers with CTCL, but information about comorbidities is limited. A total of 144 patients with CTCL at Helsinki University Central Hospital during 2005 to 2015 were studied to determine associated comorbidities and causes of death in this cohort. Compared with an age-standardized control population, the prevalence of type 2 diabetes mellitus was increased among patients with CTCL with no link to obesity...
