A lung biopsy is an interventional procedure performed to diagnose lung pathology by obtaining a small piece of lung which is examined under a microscope. [ 1 ] [ 2 ] Beyond microscopic examination for cellular morphology and architecture, special stains and cultures can be performed on the tissue obtained.
The study found that these tumor cells expressed: the EWSR1-CREB3L1 fusion gene in 7 cases, the EWSR1-CREB3L2 fusion gene in 1 case, the FUS-CREB3L2 fusion gene in 3 cases, the YAP1-KMT2A fusion gene in 2 cases, other types of rearrangements (e.g. deletions) in one or both of their EWSR1 genes in 12 cases, and inconclusive results in 1 case.

Since laboratory testing, imaging, and bronchoalveolar lavage results are often non-specific, guidelines recommend surgical biopsy to diagnose desquamative interstitial pneumonia if high-resolution computed tomography does not reveal classic signs of interstitial pneumonia. [17] A definitive diagnosis of DIP relies on a lung biopsy. [18]
To confirm the diagnosis, a doctor may perform a lung biopsy using a bronchoscope. Many times, a larger specimen is needed and must be removed surgically. Plain chest radiography shows normal lung volumes, with characteristic patchy unilateral or bilateral consolidation. Small nodular opacities occur in up to 50% of patients and large nodules ...
The diagnosis of lung cancer is based on chest radiograph and computed tomography (CT) scans, and is confirmed by biopsy. Biopsy is usually performed via bronchoscopy or CT-guided biopsy. Treatment and prognosis depend upon the histological type of cancer, the stage, and the patient's performance status. Treatments include surgery, chemotherapy ...
Matthew Perry's initial autopsy results are inconclusive pending a toxicology report, authorities said Sunday. The cause of death has been "deferred," and further investigation has been requested ...
