Institute für Pathologie und Neuropathologie, Universität Hamburg, Universitätsklinikum Hamburg-Eppendorf, Martinistraße 52, 20246, Hamburg, Deutschland.

The 2017 WHO classification of pituitary tumors is still based on structural analyses and expression of various pituitary hormones. Three innovations have to be considered: (1) The expression of pituitary transcription factors Pit‑1, T‑Pit and SF‑1. (2) The term "atypical adenoma" was replaced by "aggressive adenoma". Read More

Transplant-associated thrombotic microangiopathy in pediatric patients: pre-HSCT risk stratification and prophylaxis.

Blood Adv 2021 Apr;5(8):2106-2114

Division of Pediatric Allergy, Immunology, and Bone Marrow Transplant.

Transplant-associated thrombotic microangiopathy (TA-TMA) is an endothelial injury syndrome that complicates hematopoietic stem cell transplant (HSCT). Morbidity and mortality from TA-TMA remain high, making prevention critical. We describe our retrospective single-center experience of TA-TMA after pediatric allogeneic HSCT and present a novel pre-HSCT risk-stratification system and prophylaxis regimen. Read More

Altered Spectrum of Lymphoid Neoplasms in a Single-Center Cohort of Common Variable Immunodeficiency with Immune Dysregulation.

J Clin Immunol 2021 Apr 19. Epub 2021 Apr 19.

University of Freiburg, Freiburg, Germany.

Purpose: Common variable immune deficiency (CVID) confers an increased risk of lymphoid neoplasms, but reports describing the precise WHO specification of the lymphoma subtypes and their immunological environment are lacking. We therefore classified lymphomas-occurring in a cohort of 21 adult CVID patients during a 17-year period at our center-according to the 2016 WHO classification and characterized the local and systemic immunological context RESULTS: The median time between the onset of CVID and lymphoma was 14 years. Patients showed a high prevalence of preceding immune dysregulation: lymphadenopathy (n = 13, 62%), splenomegaly (n = 18, 86%), autoimmune cytopenia (n = 14, 67%), and gastrointestinal involvement (n = 15, 71%).

What's new in the pathogenesis and treatment of therapy-related myeloid neoplasms.

Blood 2021 Apr 19. Epub 2021 Apr 19.

2Saint Camillus International University of Health Sciences, Italy.

Therapy-related myeloid neoplasms (t-MN) include diseases onsetting in patients treated with chemo- and/or radiotherapy for a primary cancer, or an autoimmune disorder. Genomic variants, in particular in familial cancer genes, may play a predisposing role. Recent advances in deep sequencing techniques have shed light on the pathogenesis of t-MN, identifying clonal hematopoiesis of indeterminate potential (CHIP) as a frequent first step in the multi-hit model of t-MN.

J Vis Exp 2021 Apr 1(170). Epub 2021 Apr 1.

Department of Developmental and Molecular Biology, Albert Einstein College of Medicine; Department of Medicine (Hepatology), Albert Einstein College of Medicine; Einstein-Mount Sinai Diabetes Research Center, Albert Einstein College of Medicine; Marion Bessin Liver Research Center, Albert Einstein College of Medicine;

Liver cancer is currently the third leading cause of cancer related death worldwide, and Hepatocellular Carcinoma (HCC) accounts for 75-90% of all liver cancer cases. With the introduction of effective treatments to prevent and treat hepatitis B/C, non-alcoholic fatty liver disease (NAFLD), and the more aggressive form know as non-alcoholic steatohepatitis (NASH), are quickly becoming the number one risk factors to develop HCC in modern societies. To better understand the role NASH has on the development of HCC we designed a NASH-associated HCC zebrafish. Read More

J Pathol 2021 Apr 19. Epub 2021 Apr 19.

Department of Pathology, Sol Goldman Pancreatic Cancer Research Center, Johns Hopkins University School of Medicine, Baltimore, Maryland, USA.

Epigenetic alterations are increasingly recognized as important contributors to the development and progression of pancreatic ductal adenocarcinoma (PDAC). 5-hydroxymethylcytosine (5hmC) is an epigenetic DNA mark generated through the ten-eleven translocation (TET) enzyme-mediated pathway and is closely linked to gene activation. However, the timing of alterations in epigenetic regulation in the progression of pancreatic neoplasia is not well understood. Read More

A lung mass: Not the usual suspect, but not above suspicion.

Respir Med Case Rep 2021 18;33:101389. Epub 2021 Mar 18.

Department of Respiratory and Critical Care Medicine, Changi General Hospital, Singapore.

Lipoid pneumonia is an entity that is not commonly thought of when faced with opacities on the chest radiograph. The radiological changes of lipoid pneumonia can mimic pneumonia or malignancy. Due to this mimicry, it is commonly missed and alternative diagnoses should always be considered and ruled out when suspecting lipoid pneumonia. Read More

Cytomegalovirus-associated esophagitis on early esophageal cancer in immunocompetent host: a case report.

Gut Pathog 2021 Apr 16;13(1):24. Epub 2021 Apr 16.

Department of Endoscopy, New Tokyo Hospital, 1271 Wanagaya, Matsudo, Chiba, 270-2232, Japan.

Background: Cytomegalovirus (CMV)-associated gastrointestinal diseases usually occur in immunocompromised patients; however, few cases has also been described in healthy hosts despite still unclear pathological mechanisms. CMV esophagitis causes various lesions, such as erythematous mucosa, erosions, and ulcers, although such inflammatory changes can appear in superficial esophageal cancers or in surrounding areas. CMV-associated esophagitis has been also reported in cancer patients, but typically in those with advanced and/or terminal stage cancers secondary to chemoradiotherapy-induced immunosuppression or the physiologic demands of the malignancy itself.
