: RAS guanyl-releasing protein 1 (RASGRP1) deficiency is characterized by immune dysregulation and Epstein-Barr virus (EBV)-related lymphoproliferation. Diffuse mesangial sclerosis is one of the infrequent causes of infantile nephrotic syndrome. : Here, we described a 7-year-old girl who was diagnosed with diffuse mesangial sclerosis at 5 months old and subsequently developed chronic bilateral neck swelling at the age of 3 years.

Introduction: Hepatitis C virus (HCV) infection represents a significant global health burden, particularly due to its extrahepatic immune-mediated manifestations, such as mixed cryoglobulinemia, associated vasculitis (CryoVas), and non-Hodgkin B-cell lymphoma (B-NHL), which pose significant challenges. The advent of direct-acting antiviral (DAA) has changed the therapeutic landscape for HCV-related complications.
Areas Covered: This review explores the evolving epidemiology and management of HCV extrahepatic manifestation and lymphoproliferative disorders in the era of DAAs.

While the latest WHO classification of hematological neoplasms helps refine the diagnostic criteria for anaplastic large cell lymphomas (ALCL), their diagnosis can still be challenging. This retrospective series of 10 ALCL cases illustrates the cytological appearance and immunological profile obtained through flow cytometry (FCM) from various sample types, including lymph node biopsies (LN), peripheral blood (PB), cerebrospinal fluid (CSF), and pleural fluid (PF). ALCL exhibits a polymorphic cytological appearance, ranging from "doughnut" cells to Hodgkin-like cells, very large cells, and small cells, with this polymorphism being particularly pronounced in ALK (-) forms.
