Atopic dermatitis (AD) is a chronic, relapsing inflammatory skin disorder characterized by intense pruritus, eczematous lesions, and significant impairment of quality of life. In severe or chronic cases, AD can present with diverse atypical phenotypes,…
Currently, CAR-T cell therapy bridging to allogeneic hematopoietic stem cell transplantation (allo-HSCT) has become a pivotal therapeutic strategy for refractory/relapsed hematologic malignancies. Sequential therapy with CD7 chimeric antigen receptor T…
Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is an aggressive hematologic malignancy with limited therapeutic options for patients ineligible for allogeneic hematopoietic stem cell transplantation (allo-HSCT). While CD123-targeted therapies and…
Immunoglobulin light chain (AL) amyloidosis and POEMS syndrome are plasma cell proliferative disorders involving multiple organs and tissues, often presenting with nonspecific clinical manifestations. The co-occurrence of both conditions in a single pa…
BackgroundFocal segmental glomerulosclerosis (FSGS) is a heterogeneous glomerular disease frequently treated with high-dose glucocorticoids and calcineurin inhibitors, which can markedly increase susceptibility to opportunistic infections.Case presenta…
IntroductionDiGeorge syndrome (DGS) is an inborn error of immunity characterized by wide phenotypic variability, with a broad spectrum of autoimmune manifestations, including autoimmune cytopenias, thyroiditis, and juvenile idiopathic arthritis (JIA). …
Chronic myeloid leukemia (CML) with megakaryoblastic blast crisis (MKBC) as the initial manifestation is extremely rare, accounting for less than 3% of all CML cases. Philadelphia chromosome-positive acute myeloid leukemia, FAB M7 subtype (Ph+ AML-M7),…
BackgroundSevere cutaneous ulceration in antiphospholipid syndrome (APS) with concurrent infection and thrombocytopenia presents a therapeutic dilemma: standard immunosuppression risks worsening infection, while anticoagulation risks hemorrhage. We pre…
BackgroundIgG4-related disease (IgG4-RD) is a systemic immune-mediated fibrosing inflammatory disorder with multi-organ involvement. Due to highly variable and nonspecific clinical manifestations, atypical cases are prone to misdiagnosis and missed dia…
BackgroundHemophagocytic lymphohistiocytosis (HLH) is a life-threatening hyperinflammatory syndrome that can obscure underlying malignancies, particularly aggressive B-cell lymphoma. Severe cytopenias and coagulopathy often preclude conventional biopsy…
