All are true regarding Sarcoidosis except -
1. Dry cough
2. Exertional Dyspnoea
3. Wheezing
4. Hemoptysis
Pathology Answer: 4
Sarcoidosis is a systemic granulomatous disorder of unknown etiology that can
affect any organ in the body. It is characterized by the formation of non-caseating
granulomas, which are clumps of inflammatory cells that cluster together in
response to an unidentified antigen. The lungs and lymph nodes are most commonly
involved. Here's a detailed explanation for each of the options:
1. Dry cough: This is a common symptom of pulmonary sarcoidosis. The cough is
usually persistent and non-productive, meaning it does not bring up mucus or
phlegm. The presence of a dry cough is not contradicted in the statement "All
are true regarding Sarcoidosis except," so this option is not the correct
answer.
2. Exertional dyspnoea: Shortness of breath on exertion can occur in individuals
with pulmonary sarcoidosis due to the inflammation and granuloma formation in
the lungs. This symptom can be a result of the impaired lung function and
decreased lung capacity caused by the disease. Therefore, this is also a true
statement regarding sarcoidosis.
3. Wheezing: Wheezing is a high-pitched whistling sound that occurs during
breathing, typically heard when airways become narrowed or blocked. It can be a
symptom of pulmonary sarcoidosis, particularly if the disease involves the
bronchi and bronchioles, leading to bronchial obstruction and airflow
limitation. However, it is not the primary symptom and may be less common than
the other respiratory symptoms mentioned.
4. Hemoptysis: While hemoptysis, or coughing up blood, is not a hallmark symptom
of sarcoidosis, it can occur in some cases, particularly when the granulomas are
located in the lungs. It is usually mild and self-limited, but severe cases can
lead to significant bleeding. This is a true statement regarding sarcoidosis, as
it is a possible, although less common, respiratory symptom of the disease.
Since all the options (1, 2, and 4) are true regarding Sarcoidosis
