We report a 51-year-old patient who developed abdominal lymphadenopathy following Hodgkin's disease seven years after she was diagnosed as having sarcoidosis. The patient had been treated with steroids, methotrexate and azathioprine. After three cycles of chemotherapy for Hodgkin's disease, the patient again developed sarcoidosis in the mediastinal lymph nodes. A greater awareness of the co-existence of sarcoidosis and Hodgkin's disease could circumvent the diagnostic difficulties.

Synchrony in neuronal networks is crucial for cognitive functions, motor coordination, and various neurological disorders. While traditional research has focused on pairwise interactions between neurons, recent studies highlight the importance of higher-order interactions involving multiple neurons. Both types of interactions lead to complex synchronous spatiotemporal patterns, including the fascinating phenomenon of chimera states, where synchronized and desynchronized neuronal activity coexist.

: 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.

The authors describe a rare case of non-Hodgkin lymphoma (NHL) with primary involvement of the external auditory canal (EAC) and subsequent dissemination to the central nervous system, initially manifesting as a benign ear infection. This case highlights the importance of considering differential diagnoses in patients with persistent or worsening symptoms unresponsive to empirical treatment. A 53-year-old man presented with a one-week history of aural fullness, otalgia, and otorrhea in the left ear.

BACKGROUND Simultaneously occuring diffuse large B-cell lymphoma (DLBCL) and Hodgkin lymphoma (HL) is extremely rare. Generally, patients with CD20-positive DLBCL receive rituximab, cyclophosphamide, vincristine, doxorubicin, prednisone (R-CHOP) regimen, while those with HL receive brentuximab vedotin, doxorubicin, vinblastine, dacarbazine (A-AVD) regimen as first-line therapy. Establishing a strategy for treating both lymphoma subtypes concurrently is thus very difficult.
