The combination of EBUS-TBNA and the PAB antibody led to a successful treatment for lung cancer in a patient with asymptomatic sarcoidosis mimicking nodal metastasis

Publication date: Available online 18 October 2018Source: Respiratory Medicine Case ReportsAuthor(s): Mari Tone, Nobuyasu Awano, Minoru Inomata, Naoyuki Kuse, Tatsunori Jo, Hanako Yoshimura, Yoshiaki Furuhata, Tamiko Takemura, Toshio Kumasaka, Takehiro IzumoAbstractCorrect staging of lung cancer is important for the selection of the best therapy, but discriminating between lymphadenopathy from lung cancer and from sarcoidosis by imaging examinations is difficult. Additionally, distinguishing lymphadenopathy of sarcoidosis from sarcoid reactions which are sometimes caused by lung cancer is difficult on imaging and pathological findings. A 73-year-old woman was diagnosed as lung cancer clinical T1bN3M0 stage ШB based on false-positive 18F-fluoro-2-deoxyglucose positron emission tomography uptake. Because the effects of chemotherapy were different between the lymphadenopathy and the primary lesion, endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) was performed and revealed sarcoidosis as the cause of the lymphadenopathy with using a specific monoclonal antibody against Propionibacterium acnes (PAB antibody). Accordingly, the stage was changed to clinical T1bN0M0 stage ІA, for which radical operation was performed. EBUS-TBNA should be performed aggressively when the effect of chemotherapy is different between lymphadenopathies and other lesions, and the PAB antibody can help to discriminate between sarcoidosis and sarcoid reactions caused by lung can...

ConclusionsSAA is a promising marker of disease severity in patients with IPF. Our preliminary data suggest a potential pathogenetic role of alteration in lipid metabolism in this rare disease.

We reported a patient with a history of heavy smoking with particular image features of CD, which presented as mediastinal lymphadenopathy and peribronchovascular interstitial thickening mimicking lung cancer or sarcoidosis initially. Castleman's disease (CD) is an uncommon lymphoproliferative disorder characterized as either unicentric or multicentric presentation based on the involving sites. The most frequent presentation of CD is a solitary mediastinal mass. We reported a patient with a history of heavy smoking with particular image features of CD, which presented as mediastinal lymphadenopathy and peribronchovascular ...

ConclusionAbdominal irAEs were detected on CT in 13% of NSCLC patients treated with nivolumab, and colitis, in the pancolitis form, was the most common irAE. Given the expanding role of immunotherapy, radiologists should be aware of the frequency and imaging manifestations of abdominal irAEs and the impact on patient management.

We describe a 16-year-old high school student referred for management of achalasia who turned out to have pseudoachalasia due to adenocarcinoma of the cardia. He was cured with preoperative chemotherapy followed by radical surgery. Therapy of pseudoachalasia secondary to neoplasia is directed against the tumor or may be palliative to keep the lumen open. Other causes of pseudoachalasia include esophageal motility disturbances as a paraneoplastic phenomenon (e.g., with small cell lung cancer), post fundoplication or post bariatric surgery, in association with a thoracic aortic aneurysm, or with sarcoidosis or amyloidosis. T...

Abstract A 69-year-old woman was diagnosed with sarcoidosis, which was not treated with corticosteroid therapy. Her levels of angiotensin converting enzyme decreased significantly over 4 years and a mass lesion was detected near the lower part of her left main bronchus, and diagnosed as small cell lung cancer (SCLC). Treatment of the SCLC with a series of chemotherapeutic agents produced excellent results. The pulmonary sarcoidosis did not show any deterioration despite the frequent use of amrubicin, which is known to be a cause of interstitial pneumonia. This is a case report of SCLC complicated with sarcoidosis ...

Conclusion: The pillars of radiological diagnosis of destructive pulmonary TB are less thickness of the cavity wall, even interior contouring, rounded polygonal form. Non-tuberculous and cancer cavities are characterized by thicker walls, uneven interior contouring, polygonal fissured form.

Conclusion: The surviving patients ameliorated without treatment. ATS criteria for nontuberculous mycobacterial lung disease were not met in the majority of cases. Clinical significance is uncertain. M. basiliensis seems to cause colonization or asymptomatic infection rather than disease.

In cases of hard rubbery lymph nodes like in Sarcoidosis and Lymphoma, it is sometimes difficult to obtain optimum cytology samples during EBUS TBNA (Transbronchial needle aspiration cytology) and thus the diagnostic yield of EBUS TBNA samples drops down to 60%. An EBUS TBNB sample from such lymph nodes can help to increase the diagnostic yield.Methods: We did a Pilot study in patients presenting with hard rubbery lymph nodes during EBUS TBNA, EBUS guided Transbronchial biopsy of the subcarinal lymph node was done with small size biopsy forceps. Diagnostic yield of biopsy samples was compared with EBUS TBNA cytology result...

We describe a cohort of patients who have evidence of granulomatous inflammation during EBUS-TBNA (endobronchial ultrasound-guided transbronchial needle aspiration) done for the investigation of sarcoidosis and staging of a known lung cancer.Out of 800 EBUS performed between May 2010- Nov 2017, 500 yielded a benign diagnosis (men 55.6%). Rapid on-site evaluation by a cytopathologist was done in 82% of procedures and yielded a diagnosis in 86.8%.In the setting of suspected sarcoidosis (59.3%), the mean diagnostic yield was 61.05%, ATS Station 7 being the most commonly sampled lymph node (66.67%)Granulomatous inflammation wa...
