32. Sarcoidosis – BHL

Last updated on January 17, 2019 at 16:28

Organ: Lung with hilar lymph nodes

Description:

We can see three enlarged lymph nodes in the hilum. They have white scarring.

Diagnosis: Sarcoidosis (Bilateral Hilar Lymphadenomegaly)

Causes:

  • Unknown cause

Theory:

Sarcoidosis is a disorder that can affect many organs, especially the lungs but also eyes, bone marrow and skin. It’s characterized by non-caseating granulomatous inflammation, meaning it doesn’t produce caseous necrosis (like tuberculosis does) but still forms granulomas.

The cause is still unknown. It might be caused by a pathogen but we don’t know which one. It affects young females most commonly.

A symptom of sarcoidosis is enlargement of the lymph nodes of the hilum bilaterally, or in other words, bilateral hilar lymphadenomegaly.

Diagnosis is made by x-ray and biopsy.

The white scarring seen on the preparation is the result of granulomas.

    1. I encourage everyone to challenge these professors if you meet them. Just because they’re professors doesn’t mean they’re right. At least my teacher told us it’s more common in females.

      Thanks for the note.
