A 35-year-old woman had undergone extensive thymothymectomy for type A thymoma several years ago. However, two small lung nodules were found 4 and 5 years after surgery. After a partial lung resection to remove these nodules, pathology revealed that they were metastases of the type A thymoma. A pathological re-evaluation confirmed that the primary tumor had in fact been an atypical type A thymoma variant, a subset added to the WHO classification in 2015. Pathology should be re-evaluated in all patients diagnosed with type A thymoma before 2015 since they may have the more aggressive atypical type A thymoma variant...

REVIEW
Zhaohua Xia, Kun Qiao, Jianxing He
Pulmonary tuberculoma are benign solitary pulmonary nodules representing up to 25% of all resected solitary pulmonary nodules. However, the differentiation between pulmonary tuberculoma and lung cancer, as well as between active tuberculoma and inactive tuberculoma remains a clinical challenge. The present review summarizes the recent advances in the management of pulmonary tuberculoma, including radiological findings, the response to anti-tuberculosis treatment and surgical treatments. Application of the novel tubeless video-assisted thoracoscopic surgery (VATS) technique in both the diagnosis and treatment of pulmonary tuberculoma has been found to be safe and feasible and leads to less surgical trauma, which results in reduced length of hospitalization and better post-operative quality of life...

A 63-year-old woman who underwent a left hepatic lobectomy for hilar cholangiocarcinoma was referred to our department for further management. Chest computed tomography showed a lung nodule that was increased in size to 8 mm in the S4a. The differential diagnosis was metastasis versus primary lung cancer. Thoracoscopic left S4a subsegmentectomy was performed. The operative time was 158 min. The blood loss was minimal. Air leakage was not observed, and a chest tube was removed on POD 1. The patient was discharged home on POD 3...

Surgery for pulmonary metastasis is performed heterogeneously with regard to surgical approach [open vs. video-assisted thoracoscopic surgery (VATS)] and resection techniques (e.g., laser enucleation, electro-cautery resection, stapling). Complete tumor resection and preservation of lung parenchyma are of upmost importance. This is technically challenging, especially for central lesions close to vascular and bronchial segmental structures. Thus, simple thoracoscopic wedge resections are often not feasible. A VATS lower lobe bisegmentectomy (S7/8) was performed on a 62-year-old patient with a suspicious pulmonary nodule and a history of hemicolectomy for colorectal carcinoma...

A 64-year-old woman was admitted to our hospital with a 16-mm non-solid tumor with pure ground-glass nodule (GGN) contents in the posterior segment near the anterior segment of her right upper lung lobe that was suspicious of adenocarcinoma in situ (AIS). Three-dimensional computed tomography (3DCT) simulation was performed to identify the subsegmental artery and vein pre- or intra-operatively. Port-access thoracoscopic bisubsegmentectomy of the right upper lobe was performed. A frozen section revealed AIS...

A 69-year-old male patient with a history of melanoma and prostate cancer was found to have a 2.6 cm PET-avid, slowly enlarging, left upper lobe lung nodule that was suspicious for either metastasis or primary lung cancer. Due to the deep location of the nodule, a wedge resection was not recommended. A diagnostic and therapeutic uniportal video-assisted thoracoscopic surgery (U-VATS) left upper lobe trisegmentectomy was performed uneventfully. Final pathology confirmed the presence of metastasis from prostate cancer without lymph node involvement...

Uniportal video-assisted thoracoscopic surgery (VATS) has now evolved into a sophisticated technique that can be used in some of the most complex thoracic procedures; however, this approach to segmentectomy is not standardized, and the surgical procedure varies between surgeons. Here, we describe the use of our uniportal VATS procedure during right upper posterior segmentectomy in a patient with a nodule in the right upper lobe. Subsequent mediastinal lymphadenectomy was performed. The patient has recovered well after surgery...

Segmentectomy is one of the treatment of choice for small-sized non-small cell lung cancer (NSCLC). Although simple segmentectomy is feasible even if under thoracoscopy, complicated segmentectomy which contains more than two segmental plane divisions is difficult especially thoracoscopic surgery. We here present the case of totally thoracoscopic segmentectomy between upper division and lingular segment. In the first case, the 64-year-old female patient admitted for further examination and treatment of left lung ground glass nodule...

Histoplasmosis is a common endemic mycosis in North, Central, and South America, but Korea is not known as an endemic area. We treated an immunocompetent Korean patient who had histoplasmosis. A 65-year-old Korean man presented with multiple pulmonary clumps of tiny nodules in the both lungs. He had been diagnosed 40 years earlier with pulmonary tuberculosis (TB) and a fungus ball had been diagnosed 4 years earlier. He denied any history of overseas travel. The patient visited our hospital with dyspnea, blood-tinged sputum, and weight loss, which had appeared 2 months earlier...

Intention: How lncRNA SNHG1 influences the aggressiveness of nasopharyngeal carcinoma cells as well as the underlying mechanism was studied. METHODS: The lncRNA differences were analyzed by GSE12452 gene microarray. The expression of SNHG1, MiR-145-5p and NUAK1 was identified by qRT-PCR and western blot. Transfection was conducted to construct nasopharyngeal carcinoma cells with different expressions of SNHG1 and miR-145-5p. Dual-luciferase reporter assay was performed to explore the relationship between miR-145-5p and NUAK1...

Searching for targets in the visual world, or visual search, is something we all do every day. We frequently make 'false-negative' errors, wherein we erroneously conclude a target was absent when one was, in fact, present. These sorts of errors can have tremendous costs, as when signs of cancers are missed in diagnostic radiology. Prior research has characterized the cause of many of these errors as being due to failure to completely search the area where targets may be present; indeed, roughly one-third of chest nodules missed in lung cancer screening are never fixated (Drew, Võ, Olwal, Jacobson, Seltzer and Wolfe, Journal of Vision 13:3, 2013)...

Samjot Singh Dhillon, Kassem Harris
Peripheral pulmonary lesions (PPLs) are generally considered as lesions in the peripheral one-third of the lung although a precise definition and radiographic anatomical landmarks separating central and peripheral lesion does not yet exist. The radiographic detection of such lesions has increased significantly with the adoption of lung cancer screening programs. These lesions are not directly visible by regular flexible bronchoscopes as they are usually distal to the lobar and segmental bronchi. Traditionally, depending on location and clinical stage at presentation, these lesions were typically sampled by computerized tomography (CT) guided needle or surgical biopsy although some centers also used ultrasound and fluoroscopy guided percutaneous needle biopsy...

An 82 year-old male was referred to us because of a nodule in the upper lobe of his right lung, which was incidentally found by computed tomography (CT) carried out in the course of treating pneumonia. The nodule was identified as non-keratinizing squamous cell carcinoma of the lung by bronchoscopy. A close investigation revealed the tumor to be cT1bN3M1b, clinical Stage IV. Although we only adopted a wait-and-see approach because of his age and his suspected myelodysplastic syndrome, the nodule had regressed on CT images after a year...

Lung cancer screening with low-dose CT can save lives. This European Union (EU) position statement presents the available evidence and the major issues that need to be addressed to ensure the successful implementation of low-dose CT lung cancer screening in Europe. This statement identified specific actions required by the European lung cancer screening community to adopt before the implementation of low-dose CT lung cancer screening. This position statement recommends the following actions: a risk stratification approach should be used for future lung cancer low-dose CT programmes; that individuals who enter screening programmes should be provided with information on the benefits and harms of screening, and smoking cessation should be offered to all current smokers; that management of detected solid nodules should use semi-automatically measured volume and volume-doubling time; that national quality assurance boards should be set up to oversee technical standards; that a lung nodule management pathway should be established and incorporated into clinical practice with a tailored screening approach; that non-calcified baseline lung nodules greater than 300 mm3, and new lung nodules greater than 200 mm3, should be managed in multidisciplinary teams according to this EU position statement recommendations to ensure that patients receive the most appropriate treatment; and planning for implementation of low-dose CT screening should start throughout Europe as soon as possible...

Recently reported studies have associated radiation exposure from computed tomography (CT) scanning with small excess cancer risks. However, since existing medical records were used in these studies, they could not control for reasons for the CT scans and therefore, the results may have been confounded by indication. Here we conducted a study to estimate potential indication bias that could affect hazard ratios for colorectal, lung and female breast cancers by reasons for a CT scan. This involved a retrospective cohort study of electronic records from all patients aged 18-89 years without previous cancer diagnoses, who received at least one CT scan at Columbia University Medical Center in the period of 1994-2014...

Background: Pulmonary nodules are symptoms of lung cancer. The shape and size of these nodules are used to diagnose lung cancer in computed tomography (CT) images. In the early stages, nodules are very small, and radiologist has to refer to many CT images to diagnose the disease, causing operator mistakes. Image processing algorithms are used as an aid to detect and localize nodules. Methods: In this paper, a novel lung nodules detection scheme is proposed. First, in the preprocessing stage, our algorithm segments two lung lobes to increase processing speed and accuracy...
