Let an agent explain lesions in general terms, relay classification, examples and description from clinical sources, describe the named forms, route concerning lesions to medical assessment, and distinguish lesions from symptoms, tumours as a subset, normal variants and artefacts, without diagnosing individuals.

Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain lesions in general terms, relay classification, examples and description from clinical sources, describe the named forms, route concerning lesions to medical assessment, and distinguish lesions from symptoms, tumours as a subset, normal variants and artefacts, without diagnosing individuals.

Any abnormal change or damage in a tissue or organ due to disease or injury, from wounds and ulcers to tumours and areas of infection, described by location, appearance and cause; forms the registry aliases name include skin lesions, mouth lesions, the brown tumour of bone seen in hyperparathyroidism, skip lesions that leave healthy tissue between affected areas as in Crohn disease, and pseudotumours and pseudocysts, which mimic tumours or cysts without being true ones. Lesions are findings that need clinical interpretation, and new, changing, bleeding or non-healing lesions, especially of the skin, should be assessed by a doctor.

What it is for: Not applicable; a clinical finding.

It can be explain classification; relay examples and description; describe named forms; route concerning lesions.

Distinguishing features

Abnormal tissue change

Described systematically

Many causes

A finding, not a diagnosis

What it looks like

Varied; from a red skin patch or ulcer to a mass seen on imaging.

Physical character

description axes: site, size, shape, colour, margin list

skip lesions: characteristic of Crohn disease note

registry parents: physiological damage, clinical sign note

How it is recognised

Abnormal change or damage in tissue

Brown tumor, lesions in mouth, skin lesion, pseudotumor, pseudocyst, skip lesion

Symptoms are what a person feels; tumours are a kind of lesion; normal variants are not damage; artefacts are imaging errors

What the second pass must settle

  • How should lesion description standards be linked?
  • Should pseudotumour be clarified?
