Pathophysiology

Physiology

The normal physiology of [name of process] can be understood as follows:

Pathogenesis

  • The exact pathogenesis of [disease name] is not completely understood.

OR

  • 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].

Overview

Pathophysiology

This is an epithelial tumor composed of large, eosinophilic cells having small, round, benign-appearing nuclei that have large nucleoli. It is thought to arise from the intercalated cells of collecting ducts. It is not an uncommon tumor, accounting for approximately 5% to 15% of surgically resected renal neoplasms. Ultrastructurally, the eosinophilic cells have numerous mitochondria. In gross appearance, the tumors are tan or mahogany brown, relatively homogeneous, and usually well encapsulated. However, they may achieve a large size (up to 12 cm in diameter). Although anecdotal cases with metastases have been reported, the tumor is considered benign. There are some familial cases in which these tumors are multicentric rather than solitary. [1]
