Let an agent explain granulomas and how they form, describe the conditions in which they occur in general terms, describe diagnosis and management as documented, 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 granulomas and how they form, describe the conditions in which they occur in general terms, describe diagnosis and management as documented, and route personal questions to clinicians.

A small organised collection of immune cells, mainly macrophages, that forms in tissue in response to persistent infection, foreign material or inflammation that the body cannot eliminate, seen in conditions such as tuberculosis, sarcoidosis, fungal infections, foreign body reactions, dental apical granulomas and some skin and lung disorders; granulomas are identified by pathology and imaging and managed by treating the underlying cause, and this entry gives general information only.

What it is for: Organised immune cell collections in tissue.

It can be explain formation; describe associated conditions; describe diagnosis and management generally; route personal questions.

Distinguishing features

Macrophage-based

Chronic inflammation

Many causes

Pathological hallmark

What it looks like

Small nodules in tissue, seen on imaging or under the microscope.

How it is recognised

Organised macrophage aggregate

Response to persistent stimulus

A tumour is neoplastic; an abscess is a pus collection
