Sarcoidosis of the lung
- Necrosis around granuloma
- lymphocytes
* *3. giant cells***
* *4. epithelioid cells*** - BTNL gene
- lymph nodes, spleen, liver, bone barrow, skin, salivary glands, muscle

What are the causes of this lesion?
![](https://s3.amazonaws.com/brainscape-prod/system/cm/405/727/478/q_image_thumb.png?1613764348)
Sarcoidosis of the lung
- Worldwide disease affecting all races and sexes
- Causes are multifactorial – environmental and genetic (BTNL gene)

What type of cells are present?
![](https://s3.amazonaws.com/brainscape-prod/system/cm/405/727/491/q_image_thumb.png?1613764998)
Sarcoidosis of the lung
Granuloma - lymphocytes, giant cells, epithelioid cells (macrophages)
Asteroid bodies (star-shaped crystals) may be seen inside giant cell
Schaumann bodies (small calcifications with a laminar structure) may be present inside Langhans cells
