cyst
Let an agent explain cysts and their kinds, relay causes, evaluation and treatment from medical references in general terms, route people with lumps or symptoms to clinicians, and distinguish cysts from abscesses, tumours, pseudocysts and the biological sense of cyst in microorganisms.
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 cysts and their kinds, relay causes, evaluation and treatment from medical references in general terms, route people with lumps or symptoms to clinicians, and distinguish cysts from abscesses, tumours, pseudocysts and the biological sense of cyst in microorganisms.
A closed sac-like lesion with a distinct membrane containing fluid, air or semi-solid material, arising in almost any tissue, including ganglion cysts near joints, pancreatic cysts including congenital forms, brain cysts, adrenal cysts, apical cysts at tooth roots, ovarian and kidney cysts, and cysts of infectious origin; most cysts are benign and many need no treatment, but some require imaging, drainage or surgery, and any new lump should be assessed by a clinician.
What it is for: Not applicable; a lesion.
It can be explain kinds; relay evaluation and treatment; route to clinicians; distinguish related lesions.
Distinguishing features
Membrane-lined sac
Fluid or semi-solid contents
Any tissue
Mostly benign
What it looks like
A rounded lump or a fluid-filled cavity seen on imaging.
Physical character
common skin cysts: epidermoid and pilar list
simple kidney cysts: common after 50 note
ganglion cysts: most common hand lump note
How it is recognised
Closed sac with membrane and contents
Ganglion, pancreatic, brain, adrenal, apical, ovarian, kidney cysts
An abscess contains pus from infection; a tumour is a solid mass; a pseudocyst lacks an epithelial lining; a microbial cyst is a dormant stage
Related models

In practice
Families and kinds

ovarian cysts
apical and other dental cysts
infectious cysts such as hydatid
Identifiers
MeSH D003560 Cysts
Standards and regulation
Clinical guidelines for specific cysts such as pancreatic and ovarian
No general regulation
Failure modes and hazards

- The registry entry has merged aliases naming specific cysts; should they be split off?
