acute lymphoblastic leukemia [4] lymphoma [5] [6] post-splenectomy state [7] CARD11-related congenital B cell lymphocytosis (rare, also known as BENTA disease) [8] Causes of relative lymphocytosis include: age less than 2 years; acute viral infections; connective tissue diseases, [9] thyrotoxicosis, [10] Addison's disease, [11]
Some children with autoimmune lymphoproliferative disorders are heterozygous for a mutation in the gene that codes for the Fas receptor, which is located on the long arm of chromosome 10 at position 24.1, denoted 10q24.1. [3] This gene is member 6 of the TNF-receptor superfamily (TNFRSF6).
[1] [4] Lymphocytic esophagitis does not occur with high frequency in other gastrointestinal conditions where lymphocytosis is found in the mucosa, including lymphocytic colitis and lymphocytic gastritis; however, there is a disease association with coeliac disease wherein lymphocytic inflammation occurs in the small bowel after exposure to ...
Measured by flow cytometry: Normal values <2.5% total T cells; <1% of total lymphocytes in peripheral blood; Marked elevations >5% virtually pathognomonic for ALPS; Mild elevations also found in other autoimmune diseases; Thought to be cytotoxic T lymphocytes that have lost CD8 expression; Unknown if driver of disease or epiphenomenon
[1] [2] [3] [5] Although a diagnostic workup has not been finalized, the suggested diagnostic workup includes (1) confirming HIV infection, (2) confirming six or greater months of characteristic signs and symptoms, (3) evidence of organ infiltration by CD8+ T cells, and (4) exclusion of other autoimmune conditions. [1] [3] [4] HIV infection can ...

Human herpes virus 8 (HHV8) is associated with four rare lymphoproliferative disorders: 1) a subset of diffuse large B cell lymphoma (DLBCL), b) large B-cell lymphoma arising in HHV8-associated multicentric Castleman's disease, c) primary effusion lymphoma, and 4) germinotropic lymphoproliferative disorder.
A systematic review recently reported the pooled proportion are fever 97.2%, hepatomegaly 70.2%, splenomegaly 78.4%, thrombocytopenia 90.1%, anemia 76.0%, and serum ferritin ≥500 μg/L 97.1%. The case fatality rate is 14.6% among dengue hemophagocytic lymphohistiocytosis patients. [6]
