A rare condition known as Langerhans cell histiocytosis (LCH) is characterised by the clonal growth of dendritic cells called Langerhans cells, which play a significant role in the immune system. A diverse range of clinical presentations are probable as a result of this condition's ability to develop in different systems of the body. LCH presents with variable clinical manifestations, demonstrated by a range from specific multisystem involvement to more extensive bone abnormalities. This case report details the clinical course of a four-year-old male who presented with rash on the scalp and multiple lumps on the head for the past three months and a history of polyuria for two months. The findings were indicative of Langerhans cell histiocytosis after clinical and histological investigative studies. Moreover, endocrinological investigations demonstrated the development of central diabetes insipidus, as a complication.

Clinical pancreatic islet xenotransplantation will most probably rely on genetically modified pigs as donors. Several lines of transgenic pigs carrying one and more often, multiple modifications already exist. The vast majority of these modifications aim to mitigate the host immune response by suppressing major xeno-antigens, or expressing immunomodulatory molecules that act locally at the graft site.

Human hematopoietic stem cells (HSCs) and mesenchymal stem cells (MSCs) are the major stem cells of the bone marrow and are usually isolated from the peripheral blood. In the present study, we isolated these stem cells by an apheresis method from a donor who was administered granulocyte colony-stimulating factor (G-CSF). propagation of these stem cells showed a plastic-adherence property expressing CD73 and CD105 surface markers, which is a characteristic feature of MSCs.

Objective: To explore the gene mutations of Langerhans cell histiocytosis in children, and to analyze the correlation of mutation with clinical features and prognosis of LCH, so as to provide reference for clinical diagnosis and treatment.
Methods: Fluorescence PCR was used to detect gene mutations in paraffin-embedded tissue samples from 78 children with LCH, and the correlation of mutation with clinical characteristics and prognosis of LCH in children was analyzed.
Results: Among the 78 children, 41 cases (52.

Introduction And Importance: Langerhans cell histiocytosis (LCH) is a rare disorder characterized by the proliferation of abnormal Langerhans cells, often presenting with symptoms that mimic common dermatological conditions such as hidradenitis suppurativa (HS). Accurate diagnosis is essential because LCH can affect multiple organ systems and necessitates distinct therapeutic approaches.
Case Presentation: We report a rare case of a 39-year-old male with a 7-year history of diabetes insipidus (DI), who presented with polyuria, polydipsia, and enlarging purulent lesions in the axilla and groin.

Erdheim-Chester disease (ECD) is a rare, multisystemic, non-Langerhans cell histiocytic neoplasm predominantly affecting middle-aged males in their fifth to seventh decades of life. It often presents with nonspecific symptoms, leading to a delay in its diagnosis. We report a case of an 85-year-old male with multisystemic manifestations, including retroperitoneal, skeletal, vascular, cardiac, orbital, and central nervous system (CNS) involvement.
