Research output: Contribution to journalArticlepeer-review


Sarcoidosis is protean in its presentations and requires a multimodal approach to diagnosisafter excluding more common etiologies such as asthma. Transbronchial lung biopsy andlymph node biopsy remain the most common invasive procedure to discover noncaseatinggranulomas that can confirm the clinical diagnosis of sarcoidosis. BAL, while frequentlyperformed during fiberoptic bronchoscopy, remains controversial in the diagnostic algorithmfor sarcoidosis. Given potential confounding patient factors, the clinician and pulmonologistshould exercise caution when interpreting BALF results in suspected cases of sarcoidosis. Inthe absence of confounders, BALF can be a valuable adjunct in the quest to diagnosesarcoidosis.
