Overview
The exact pathogenesis of [disease name] is not fully understood.
OR
It is thought that [disease name] is the result of / is mediated by / is produced by / is caused by either [hypothesis 1], [hypothesis 2], or [hypothesis 3].
OR
[Pathogen name] is usually transmitted via the [transmission route] route to the human host.
OR
Following transmission/ingestion, the [pathogen] uses the [entry site] to invade the [cell name] cell.
OR
[Disease or malignancy name] arises from [cell name]s, which are [cell type] cells that are normally involved in [function of cells].
OR
The progression to [disease name] usually involves the [molecular pathway].
OR
The pathophysiology of [disease/malignancy] depends on the histological subtype.
Pathophysiology
Pathogenesis
- The exact pathogenesis of [disease name] is not fully understood.
OR
- It is understood that behcet disease is the result of vasculitis. It involves all sizes of blood vessels ( small, medium, and large). Arteries and venis are both involved in behcet disease. Major mechanisms in pathogenesis of behcet disease include:
- Polygenic
- s with other autoimmune diseases, the disorder may represent aberrant immune activity triggered by exposure to an agent, perhaps infectious, in patients with a genetic predisposition to develop the disease. Major disease mechanisms in Behçet syndrome include the following
- [Pathogen name] is usually transmitted via the [transmission route] route to the human host.
- Following transmission/ingestion, the [pathogen] uses the [entry site] to invade the [cell name] cell.
- [Disease or malignancy name] arises from [cell name]s, which are [cell type] cells that are normally involved in [function of cells].
- The progression to [disease name] usually involves the [molecular pathway].
- The pathophysiology of [disease/malignancy] depends on the histological subtype.
Genetics
- [Disease name] is transmitted in [mode of genetic transmission] pattern.
- Genes involved in the pathogenesis of behcet disease include human leukocyte antigens, particularly HLA-B51. [1]
- Familial cases of behcet disease have higher rates of HLA-B51 in compare to sporadic cases.[2]
- Genetic anticipation: earlier age of onset of disease in children of pateints with behcet disease.[3]
- Some studies shows that major histocompatibility complex class I chain related gene A (MICA) A6 allele is related to behcet disease. [4]
- Non-HLA genes als have roles in behcet diesease. They include: [5][6]
- Intercellular adhesion molecule (ICAM)-1 gene
- The endothelial nitric oxide synthase gene
- TNF genes
- The vascular endothelial growth factor (VEGF) gene
- Manganese superoxide dismutase gene
- Cytochrome P450 gene
- Interleukin (IL)-10 gene
- The IL-23 receptor gene
- Non-HLA genes also play a role in determining susceptibility to disease. Genome-wide screening of affected families with more than one affected member has identified additional, non-HLA regions of potential interest [44]. Examples include associations between Behçet syndrome and:
- The development of behcet disease is the result of multiple genetic mutations.
Associated Conditions
Gross Pathology
- On gross pathology, [feature1], [feature2], and [feature3] are characteristic findings of [disease name].

Microscopic Pathology
- On microscopic histopathological analysis, [feature1], [feature2], and [feature3] are characteristic findings of [disease name].
