Pulmonary Sarcoidosis

What is sarcoidosis?

Sarcoidosis is a rare disease that results from inflammation. Ninety percent of the cases of sarcoidosis are found in the lungs, but it can occur in almost any organ.

It causes small lumps, or granulomas, which generally heal and disappear on their own. However, for those granulomas that do not heal, the tissue can remain inflamed and become scarred, or fibrotic.

Pulmonary sarcoidosis can develop into pulmonary fibrosis, which distorts the structure of the lungs and can interfere with breathing. Bronchiectasis, a lung disease in which pockets form in the air tubes of the lung and become sites for infection, can also occur.

What are the symptoms of asarcoidosis?

Most sarcoidosis patients do not exhibit symptoms and probably are unaware they have the disease. Pulmonary sarcoidosis can cause loss of lung volume (the amount of air the lungs can hold) and abnormal lung stiffness.

The following are the most common symptoms for sarcoidosis, however, each person may experience symptoms differently :

shortness of breath
cough that will not go away
skin rashes on face, arms, or shins
inflammation of the eyes
weight loss
fatigue
night sweats
fever

The symptoms of sarcoidosis may resemble other conditions or medical problems. Consult your doctor for a diagnosis.

Who is at risk for sarcoidosis?

Sarcoidosis occurs in all races and both genders, but the most susceptible populations seem to be of African-American, Scandinavian, German, Irish, or Puerto Rican origin.

Diagnosis of sarcoidosis:
In addition to a complete medical history and physical examination, diagnostic procedures may include:

chest x-ray
pulmonary function tests
blood tests
bronchoalveolar lavage
biopsy

Sarcoidosis is usually diagnosed by elimination. That is, other lung disorders that have similar symptoms are progressively eliminated, leading to a diagnosis of sarcoidosis.

Treatment for sarcoidosis:
Specific treatment will be determined by your doctor(s) based on:

your age, overall health and medical history
extent of the disease
your tolerance for specific medications, procedures or therapies
expectations for the course of the disease
your opinion or preference

Treatment may include the use of corticosteroids.
