Question 17

What characterizes stage 1 of sarcoidosis?

Answer 17

Bilateral hilar lymphadenopathy (BHL)

This stage involves enlargement of lymph nodes in both sides of the chest.

Question 18

What is the defining feature of stage 2 of sarcoidosis?

Answer 18

BHL + interstitial infiltrates

In this stage, there are both enlarged lymph nodes and lung tissue involvement.

Answer 19

Diffuse interstitial infiltrates only

This stage has no lymphadenopathy, just lung infiltration.

Question 20

What is the characteristic of stage 4 of sarcoidosis?

Answer 20

Diffuse fibrosis

This stage indicates severe lung damage and scarring.

Question 21

What onset is associated with a poor prognosis in sarcoidosis?

Answer 21

Insidious onset, symptoms > 6 months

A gradual onset and prolonged symptoms indicate a worse outcome.

Question 22

What absence is linked to poor prognosis in sarcoidosis?

Answer 22

Absence of erythema nodosum

Erythema nodosum is often a sign of a better prognosis.

Question 23

What are some extrapulmonary manifestations of sarcoidosis associated with poor prognosis?

Answer 23

Examples include:
* Lupus pernio
* Splenomegaly

These conditions indicate more extensive disease involvement.
