Pathology (article structure)

Pathology is one of the main subheadings in a standard article. 

Location

The "Pathology" subheading is located after "Clinical presentation" and before "Radiographic features".

Structure

Immediately under the "Pathology" subheading a brief introduction to the relevant pathology of the condition should be included. This typically includes cell-of-origin information.

It is important to note that the subheadings "Risk factors" and "Associations" if required should be placed in the Epidemiology section, not in pathology.

Below this, the following subheadings can be used as required. 

Etiology

Description of a condition's etiology may very well be summarized by using a bulleted list.
However if there are known risk factors and/or associations of a disease, these should be located as subheadings in the Epidemiology section.

Location

If the condition has substantial variation in distribution in the body, then the "location" subheading should be used. The subheading should not be used if no unexpected information is present. In other words, don't use the subheading for "pineocytomas" which occur only in the pineal region. 

Classification

If classification systems exist please make these into separate articles with "classification" as a section attribute and link them from here, e.g. Achilles tendon tear classification.

Macroscopic appearance

A description of the gross pathology can be included here. 

Microscopic appearance

A description of the relevant histology can be included here. 

Immunophenotype

If there are relevant immunohistochemical or immunocytological markers. 

Markers

If there are relevant serological markers.

Genetics

If there are specific features relating to genetics. This will often be alluded to in both the epidemiology and general pathology sections. 

Examples

The following articles have an appropriate Pathology section:

• glioblastoma
• hepatocellular carcinoma
