LAM is often misdiagnosed asasthmaorchronic obstructive pulmonary disease(COPD).

PLCH: Cigarette smoke has been linked to PLCH as it activates Langerhans cells in the lungs.

BHD: BHD is inherited due to an autosomal dominant genetic defect.

These can all negatively affect the lung’s lymphatic system, potentially resulting in LIP or FB.

It is rare for LIP to occur from an unknown cause.

It is extremely rare for amyloidosis to be diagnosed without one of the associated disorders.

Symptoms

Symptoms vary depending on what jot down of lung cyst you have.

Some may be asymptomatic, while others have progressive difficulty breathing.

The most common symptom is difficulty breathing; other symptoms depend on the underlying condition causing cysts.

Most treatment options focus on maintaining lung function and managing symptoms.

Many causes of lung cysts do not have a defined cure and often progress and worsen over time.

It’s essential that your healthcare provider continually monitors your symptoms to ensure optimal lung health.
