Autoimmune Lymphoproliferative Syndrome (ALPS), commonly caused by mutations in the gene, is a disease with variable penetrance. Subjects may be asymptomatic, or they may present with lymphadenopathy, splenomegaly, cytopenias, or malignancy. Prompt recognition of ALPS is needed for optimal management. We describe a multi-generational cohort presenting with clinical manifestations of ALPS, and a previously unreported heterozygous missense variant of uncertain significance in (c.758G >T, p.G253V), located in exon 9. Knowledge of the underlying genetic defect permitted prompt targeted therapy to treat acute episodes of cytopenia. This cohort underscores the importance of genetic testing in subjects with clinical features of ALPS and should facilitate the reclassification of this variant as pathogenic.

Familial hemophagocytic lymphohistiocytosis type 2 (FHL2), caused by perforin 1 (PRF 1), is a rare and fatal autosomal recessive disorder characterized by a hyperinflammatory syndrome and the accumulation of activated T lymphocytes and histiocytes in the reticuloendothelial system. Autoimmune lymphoproliferative syndrome (ALPS) is an autoimmune disease that typically presents in children with lymphadenopathy, splenomegaly, and cytopenias or lymphomas. We report a case of a 9-year-old boy who was newly diagnosed with FHL, carrying a new type of compound heterozygous mutations (c.

Background: Pediatric patients with autoimmune lymphoproliferative immunodeficiencies (ALPIDs) who exhibit autoimmune cytopenias are frequently diagnosed with immune thrombocytopenia (ITP), autoimmune hemolytic anemia (AIHA), or Evans syndrome (ES). These conditions generally necessitate long-term immunosuppressive therapy using medications that are often ineffective and highly toxic before the diagnosis of ALPIDs. A less harmful treatment strategy is needed.

Granuloma faciale (GF) is a rare, idiopathic, localized vasculitis, usually without associated systemic autoimmune disease. Primarily involving the skin, GF can also occur on the ocular surface, mimicking neoplasia and other inflammatory processes. In this report, the authors report 2 novel cases of GF in the conjunctiva, and analyze the 4 published ocular cases to better appreciate the clinical and histopathologic features of GF involving the ocular surface, and to compare the findings with those in the skin.

Hodgkin lymphoma (HL) is a malignancy of the lymphatic system often associated with immune dysfunction. This case describes an 11-year-old boy presenting with epistaxis, petechiae, and thrombocytopenia (40 000/μl), initially diagnosed as immune thrombocytopenia (ITP). Further evaluation revealed lymphadenopathy and splenomegaly.

Patients with pathogenic variants of () are known to present with autoimmune diseases, inflammatory bowel disease, lymphoproliferative disorders, allergies, immunodeficiency, and malignancies. This condition, characterized by widespread infections that impact multiple systems, has various radiological findings reported in the literature. These include computed tomography (CT) findings indicating lung involvement and magnetic resonance imaging (MRI) findings showing neurological system involvement.
