A significant sign that can be seen in the initial stage of sarcoidosis is a persistent cough. These benign phenomena may truly signify this dangerous disease. Pulmonary sarcoidosis is diagnosed in a fair number of patients with cough. The cough may be dry and chronic, possibly with other symptoms. In these cases, it is important to do trial investigations to demonstrate the fact that inflammation and infection are present.
Cough is another prevalent symptom in cases involving viruses and bacteria. On the other hand, if the test findings do not point toward pathogens, there might be a suspicion of sarcoidosis. You then need additional testing that demonstrates that granulomas are found in at least one biopsy specimen.
