Aggressive NK-cell leukemia is a disease with an aggressive, systemic proliferation of natural killer cells (NK cells) and a rapidly declining clinical course. [ 1 ] [ 2 ] [ 3 ] It is also called aggressive NK-cell lymphoma .
Natural killer cells, also known as NK cells, are a type of cytotoxic lymphocyte critical to the innate immune system.They are a kind of large granular lymphocytes [1] [2] (LGL), and belong to the rapidly expanding family of known innate lymphoid cells (ILC) and represent 5–20% of all circulating lymphocytes in humans.

Severe combined immunodeficiency (SCID), also known as Swiss-type agammaglobulinemia, is a rare genetic disorder characterized by the disturbed development of functional T cells and B cells caused by numerous genetic mutations that result in differing clinical presentations. [2]
Griscelli syndrome is a rare autosomal recessive [1] disorder characterized by albinism (hypopigmentation) with immunodeficiency, that usually causes death by early childhood. Researchers have developed three different classifications of the form of disorder, characterised by different signs and symptoms.
Using rough estimates of disease burden, a study found NIH funding for ME/CFS was only 3% to 7% of the average disease per healthy life year lost between 2015 and 2019. [96] Worldwide, multiple sclerosis , which affects fewer people and results in disability no worse than ME/CFS, received 20 times as much funding between 2007 and 2015.
POEMS syndrome (also termed osteosclerotic myeloma, Crow–Fukase syndrome, Takatsuki disease, or PEP syndrome) is a rare paraneoplastic syndrome caused by a clone of aberrant plasma cells. The name POEMS is an acronym for some of the disease's major signs and symptoms ( p olyneuropathy , o rganomegaly , e ndocrinopathy , m yeloma protein , and ...
The prognosis depends on the type of cells affected, the number of blasts in the bone marrow or blood, and the changes present in the chromosomes of the affected cells. [3] The average survival time following diagnosis is 2.5 years. [4] MDS was first recognized in the early 1900s; [5] it came to be called myelodysplastic syndrome in 1976. [5]
The syndrome is defined by the presence of; both of two major criteria, peripheral neuropathy and a clonal plasma cell dyscrasia (increased bone marrow plasma cells in ~67% of cases; ≥1 plasmacytoma in ~33% of cases); at least one other major criteria (Castleman's disease, sclerotic bone lesions, elevated serum levels of the cytokine VEGF ...
