ulcer
Let an agent explain ulcers and their kinds in general terms from clinical sources, describe causes, warning signs and management principles, distinguish skin, mucosal and internal ulcers, and route personal questions to clinicians.
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 ulcers and their kinds in general terms from clinical sources, describe causes, warning signs and management principles, distinguish skin, mucosal and internal ulcers, and route personal questions to clinicians.
A break in the skin or a mucous membrane with loss of surface tissue and disintegration and necrosis of epithelial tissue, forming an open sore that heals slowly, including mouth ulcers, oesophageal and peptic ulcers, pressure, venous and diabetic foot ulcers such as malum perforans, ulcerating tumours and infectious lesions such as the tache noire eschar of rickettsial disease; ulcers arise from pressure, poor circulation, infection, inflammation, cancer and irritation and are managed according to cause.
What it is for: Not applicable; a lesion.
It can be explain kinds and causes; relay management principles; relay warning signs; route personal questions.
Distinguishing features
Loss of surface tissue
Slow healing
Many causes
Cause-specific management
What it looks like
An open sore with a crater and surrounding inflammation.
Physical character
pressure ulcer prevalence in hospitals: about 5-15 percent - studies vary
How it is recognised
Open sore with tissue loss
Mouth, peptic, oesophageal, pressure, venous, diabetic, cancerous and infectious ulcers
Erosions are shallower; blisters are fluid-filled; wounds are acute injuries

- How should guidelines be linked?
- The registry entry has merged aliases naming distinct conditions and an eschar; should they be split off?
