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 renal oncocytoma is not completely understood.
- It is understood that [disease name] is the result of / is mediated by / is produced by / is caused by either [hypothesis 1], [hypothesis 2], or [hypothesis 3].
- [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
DNA diploidy is seen in 96% of patients with renal oncocytomas.[1][2][3]
The development of renal oncocytoma is the result of multiple genetic mutations such as:[4][5][6][7][8][9]
- Deletion of chromosome 1
- Deletion of the sex chromosome
- Translocation of chromosome 11q13
- Sporadic or no chromosomal alteration
Associated Conditions
Conditions associated with renal oncocytoma include:[10][11]
- Familial renal oncocytoma
- Birt-Hogg-Dube syndrome
Note: Birt-Hogg-Dube syndrome is an autosomal dominant syndrome which is presented with different types of dermatologic diseases and renal epithelial tumors such as renal oncocytoma and RCCs.
Gross Pathology
On gross pathology, tan to brown surface color , well-encapsulated with a thick, well-defined, fibrous capsule, central scar, and homogeneous appearance without any hemorrhage or necrosis inside it in the tumor cut are characteristic findings of renal oncocytoma.[12][13][14][15][16][17]
Microscopic Pathology
On microscopic histopathological analysis, renal oncocytoma characterized by "oncocytes". They are large, round to polygonal neoplastic cells accompanied by eosinophilic granular cytoplasm and are organized in nested or organoid pattern. Although, renal oncocytoma is benign, atypia, prominent nucleoli, and pleomorphism may seen in microscopic examination.
Pathogenesis
- Renal oncocytoma is thought to arise from the intercalated cells of collecting ducts of the kidney.[18]
