Background: Bidirectional interactions between eosinophils and mast cells (MCs) have been reported in various allergic diseases. Bone marrow (BM) eosinophilia, and to a lesser extent blood eosinophilia, is common in systemic mastocytosis (SM), but its significance remains unknown.

Objective: We described blood and BM eosinophil characteristics in SM.

Background: Mycosis fungoides (MF) usually has an indolent course. However, some patients develop more aggressive disease and few prognostic parameters have been identified. Isolated cases of pustular MF (pMF) suggest an unfavourable prognosis.

Determining lymphoma subtypes is a crucial step for better patient treatment targeting to potentially increase their survival chances. In this context, the existing gold standard diagnosis method, which relies on gene expression technology, is highly expensive and time-consuming, making it less accessibility. Although alternative diagnosis methods based on IHC (immunohistochemistry) technologies exist (recommended by the WHO), they still suffer from similar limitations and are less accurate.

Micronodular arrangement of epithelial cells and lymphoid B-cell hyperplasia with follicles are both peculiar histological features in thymic tissue. Such features may especially occur in thymic epithelial tumors. The most common form is called micronodular thymoma with lymphoid stroma.

Article Synopsis
  • * Researchers studied 67 samples from 48 patients to identify genetic changes linked to high-risk disease stages and worse survival rates, finding specific genomic alterations like gain7q and del6q16.3 associated with poor prognosis.
  • * The study revealed different evolutionary pathways of MF, as well as potential biomarkers for identifying patients at higher risk of disease progression, emphasizing the importance of genomic analysis in managing MF.

According to expert guidelines, lymph node surgical excision is the standard of care for lymphoma diagnosis. However, core needle biopsy (CNB) has become widely accepted as part of the lymphoma diagnostic workup over the past decades. The aim of this study was to present the largest multicenter inventory of lymph nodes sampled either by CNB or surgical excision in patients with suspected lymphoma and to compare their diagnostic performance in routine pathologic practice.

  • Monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL) is an aggressive, rare form of T-cell lymphoma mainly found in Asia, with a clinical study conducted on 71 European patients showing a median age of 67 years.
  • Most patients had gastrointestinal symptoms requiring emergency surgery, with around 40% diagnosed at stage IV, and tumors were classified into typical and atypical morphologies sharing similar immunophenotypic profiles.
  • The study highlighted significant genetic alterations, including mutations in genes like MYC, STAT5B, and TP53, which are associated with poor survival outcomes and treatment resistance, indicating the high clinical risk of MEITL.

  • Some cancer patients can get eye problems, even after their cancer seems to be gone.
  • The study talked about 6 unique cases where these patients had different kinds of eye issues related to their blood cancers.
  • Doctors need to watch for eye symptoms in these patients because catching problems early can help with treatment.

Article Synopsis
  • The case involves a rare type of lymphoma known as hepato-splenic Tγδ-cell lymphoma, which typically affects patients with weakened immune systems, but this one occurred in a healthy individual.
  • The patient exhibited prominent features called telangiectasias, which are small dilated blood vessels on the skin, leading to initial confusion in identifying the correct lymphoma type.
  • The diagnosis was ultimately clarified, highlighting the importance of careful evaluation to avoid misdiagnosis in similar cases.

Enteroviruses are a frequent source of infection and among the most common central nervous system viral pathogens. Enteroviruses - in particular, the Coxsackie B viruses - are a known cause of myocarditis. Rituximab is a genetically engineered chimeric anti-CD20 monoclonal antibody.

Micronodular thymic carcinoma with lymphoid hyperplasia (MNTCLH) is a rare form of thymic carcinoma. We present the experience of RYTHMIC, the French national network devoted to the treatment of thymic epithelial tumors through multidisciplinary tumor boards with a review of all tumors by pathologists for classification and staging. Six cases of MNTCLH were diagnosed during a review of 1007 thymic epithelial tumors.

Background: This study aimed to describe the physical fitness characteristics of semi-professional rugby union (RU) players using VO2max (mL. min-1. kg-1), knee peak torque (PT), mean power (MP), hamstring: quadriceps (H:Q) ratio and basic anthropometrics characteristics and to compare backs and forwards across these same characteristics.

Article Synopsis
  • A 75-year-old patient with cervical lymphadenopathy exhibited symptoms of acquired hemophilia A (AHA), including elevated aPTT and low factor VIII (FVIII) levels, with high anti-FVIII antibodies detected.
  • Histological analysis revealed benign follicular hyperplasia and elevated serum IgG4 levels, indicating the presence of IgG4-related disease (IgG4-RD).
  • The patient was treated successfully with prednisone and rituximab, leading to an exploration of the connection between AHA and IgG4-RD, eventually determining that specific anti-FVIII autoantibodies were predominantly IgG4 in subtype among cases with overlapping conditions.

Background: Classification of thymic epithelial tumours (TETs) is known to be challenging; however, the level of discordances at a nationwide level between initial and expert diagnosis and their clinical consequences are currently unknown. RYTHMIC is a national network dedicated to the management of TET based on initial histological diagnosis, followed by an additional expert review of all cases. Our aim was to evaluate the discordances between initial and expert diagnoses and whether they would have led to different clinical management.

The RYTHMIC network, supported by the French National Cancer Institute is dedicated to the management of patients with thymic epithelial tumors through regional and national multidisciplinary tumor boards. Tumor board decisions are based on the initial pathology diagnoses. However, following clinical inclusion in the network, a central pathology review is organized, implicating a panel of pathologists, for histotype and stage classification, which is different from a classical second opinion from pathologist to pathologist for a difficult case.

The purpose of this study was to quantify training loads (TL) of high intensity sessions through original methods (TRIMP; session-RPE; Work-Endurance-Recovery) and their updated alternatives (TRIMPcumulative; RPEalone; New-WER). Ten endurance athletes were requested to perform five sessions until exhaustion. Session 1 composed by a 800m maximal performance and four intermittent sessions performed at the 800m velocity, three sessions with 400m of interval length and work:recovery ratios of 2:1, 1:1 and 1:2 and one with 200m intervals and 1:1.
