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

Physiology

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

Pathogenesis

61-year-old man presented in 1972 with unrelenting pruritus of six months’ duration. On the right is his peripheral blood film stained with Periodic Acid-Schiff (PAS) showing a neoplastic T cell (Sézary cell).

Genetics

[Disease name] is transmitted in [mode of genetic transmission] pattern.

OR

Genes involved in the pathogenesis of [disease name] include:

  • [Gene1]
  • [Gene2]
  • [Gene3]

OR

The development of [disease name] is the result of multiple genetic mutations such as:

  • [Mutation 1]
  • [Mutation 2]
  • [Mutation 3]

Associated Conditions

Conditions associated with [disease name] include:

  • [Condition 1]
  • [Condition 2]
  • [Condition 3]

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].
