Endobronchial tumors cannot be visualized on standard two-view chest radiographs. The tumor is often associated with other phenomena, such as postobstructive pneumonia, atelectasis, and adenopathy. Chest CT scans may demonstrate a mass or adenopathy. In the present case, no mediastinal or hilar adenopathies were noted.6,7 Although there is a better chance of visualizing an endobronchial tumor by means of a CT scan than by means of a standard radiograph, endobronchial tumors can remain elusive on CT scans.1,7 Three-dimensional computer reconstruction (eg, virtual bronchoscopy) may be helpful in visualizing elusive tumors before invasive imaging becomes necessary. Virtual bronchoscopy uses CT images and various computer graphic systems to create a computerized graphic image of the endobronchial tree.8,9 The role of virtual bronchoscopy has yet to be fully defined with data to support its use in diagnosing endobronchial lesions.8,9 The preferable method for diagnosing an endobronchial tumor is ...

We have previously demonstrated that vascular count significantly increases in the preneoplastic lesions of the bronchial tree, starting from very low levels in the normal epithelium to a significantly higher number of microvessels in moderate dysplastic lesions and in situ carcinomas. Vascular endothelial growth factor (VEGF) protein expression has shown to be strictly associated with neovascularization both in human cancer and in various type of preinvasive lesions. A number of studies have demonstrated that mutant p53 is involved in the regulation of angiogenesis, and immunohistochemical detection of the p53 protein is associated with p53 gene mutations. In this study we looked for possible correlation between p53 protein detection, VEGF expression and vascular count in a series of preneoplastic and neoplastic lesions of the bronchial tree in order to investigate the angiogenic pattern and its genetic control in the early steps of bronchial cancer development. Twenty-four retrospective ...

Bronchial carcinoid tumors are very rare pulmonary neoplasms. They usually present with pulmonary symptoms or paraneoplastic syndromes. Typical (well-differentiated) tumors are usually indolent with survival exceeding 90% after resection. Atypical carcinoids have a worse prognosis. They are much more likely to recur locally or to have distant metastases. This case report describes a patient who presented with abdominal pain and hepatic lesions who was subsequently diagnosed to have bronchial carcinoid.
Endobronchial lipomas, usually found in the obese and in smokers, can cause patients significant distress with chronic cough, chest pain, dyspnea, and increased infection risk.
Etiology of bronchial obstruction: a) spasm; b) mucous odema; c) hypersecretion; d) scar narrowing: e) endobronchial tumor; f) external pressuring of bronchus. Surgical procedure is typically useful for COPD in chosen cases. A bullectomy is the surgical elimination of a bulla, a large air-stuffed space that can squash the encircling, more normal lung. Lung volume reduction surgery is similar; parts of the lung which might be significantly broken by emphysema are eliminated permitting the remaining, relatively good lung to increase and work better. Lung transplantation is sometimes carried out for extreme COPD, significantly in youthful people..

We submit the case of a child afflicted with a mucoepidermoid bronchial tumor. The patient is a boy, aged seven, who after undergoing antibiotic treatment for six weeks because of a fever and atelectasia-condensation in the right lower lobe showed no signs of clinical improvement and was sent to our department to undergo further study and treatment. A bronchoscopy performed shows a polypoid mass that partially blocks the main bronchial tube a few milimiters under the access to the right upper lobe. A biopsy is carried out and the anatomopathological test shows there is a low degree epidermoid carcinoma ...
Introduction: Bronchial carcinoids (BC) are rare neuroendocrine tumors. Surgery is not feasible for infiltrating and metastatic disease. Medical therapy is often tried but is represented by chemotherapy and radiation, while somatostatin analogues are employed for symptomatic control. It is necessary to identify new molecules capable of providing medical treatment in cases for which surgical removal is not feasible. EGF, TGFα are growth factors which were demonstrated to be important in neuroendocrine tumors. EGF and TGFα bind to the EGF receptor and lead to the transcription of genes that regulate cell proliferation ...
METHODS: All bronchoscopies performed for suspected bronchial carcinoma at Papworth Hospital, Cambridge, United Kingdom, over the last 3 years were reviewed retrospectively. Patients with peribronchial disease, as evidenced by submucosal infiltration or extrinsic compression on bronchoscopy, were selected for TBNA. Patients with computed tomography evidence of subcarinal lymphadenopathy were also included. In total we identified 78 patients: 67 with peribronchial disease and 21 with subcarinal lymphadenopathy. All 78 patients underwent TBNA, and in 8 of these TBNA was performed in 2 sites. ...

Endobronchial lipomas are rare benign tumors which are amenable to endoscopic management both for diagnosis and treatment. Excluding those cases that merits surgical treatment, endoscopic mechanical debulking in conjunction with other techniques actually are the preferred method of treatment as it results in complete resection and preserve lung parenchyma.1 These tumors are poorly vascularized and patients rarely present with hemoptysis, and if that is the case, it has been mainly attributed to post obstructive pneumonia or bronchiectasis rather than the tumor itself.2 With all of this in mind, we recently decided to resect a previously histologically confirmed endobronchial pedunculated lipoma which obstructs the intermediary bronchus (Fig. 1A) from a 69-year old never smoker man who has a history of recurrent right lower pneumonia and with the aid of a cold snare device (Fig. 1B) intended for percutaneous endoscopic gastrostomy (Cook Medical). In a similar way as described by other authors ...
TY - JOUR. T1 - Natural history of bronchial preinvasive lesions. AU - Ishizumi, Taichiro. AU - McWilliams, Annette. AU - MacAulay, Calum. AU - Gazdar, Adi. AU - Lam, Stephen. PY - 2010/3. Y1 - 2010/3. N2 - Preinvasive bronchial lesions defined as dysplasia and carcinoma in situ (CIS) have been considered as precursors of squamous cell carcinoma of the lung. The risk and rate of progression of preinvasive lesions to invasive squamous cell carcinoma as well as the mechanism of progression or regression are incompletely understood. While the evidence for the multistage, stepwise progression model is weak with relatively few documented lesions that progress through various grades of dysplasia to CIS and then to invasive carcinoma, the concept of field carcinogenesis is strongly supported. The presence of high-grade dysplasia or CIS is a risk marker for lung cancer both in the central airways and peripheral lung. Genetic alterations such as loss of heterozygosity in chromosome 3p or chromosomal ...
Tracheobronchial foreign body (TFB) aspiration is a common occurrence in children compared with adults. Long-standing cases of TFB aspiration during childhood presenting in an adult have rarely been reported. We report the unique case of an endobronchial Playmobil traffic cone that went undetected for 40 years and presented as a suspected bronchogenic carcinoma. This was subsequently removed successfully with flexible bronchoscopy. To our knowledge this is the first case of a TFB that was overlooked this length of time. ...
Purpose: To assess various volume based PET quantification metrics including: metabolic tumor volume (MTV) and total lesion glycolysis (TLG) with different thresholds as well as background activity based PET metrics (Background Subtracted Lesion activity (BSL) and Volume (BSV)) as prognostic markers for progression free and overall survival (PFS, OS) in early stage I and II non-small cell lung cancer (NSCLC) after resection. Patients and Methods: 133 patients received an adequate FDG PET/CT scan prior to surgery between January 2003 and December 2010. All PET activity metrics showed a skewed distribution and were log-transformed before calculating the Pearson correlation coefficients (PCC). Survival tree analysis was used to discriminate between high and low risk patients and to select the most important prognostic markers. Akaike information criterion (AIC) was used to compare two uni-variate models. Results: Within the study time 36 patients died from NSCLC and 26 patients from other causes. ...
The protein encoded by this gene acts as receptor for arginine vasopressin. This receptor belongs to the subfamily of G-protein coupled receptors which includes AVPR1A, V2R and OXT receptors. Its activity is mediated by G proteins which stimulate a phosphatidylinositol-calcium second messenger system. The receptor is primarily located in the anterior pituitary, where it stimulates ACTH release. It is expressed at high levels in ACTH-secreting pituitary adenomas as well as in bronchial carcinoids responsible for the ectopic ACTH syndrome. A spliced antisense transcript of this gene has been reported but its function is not known. [provided by RefSeq, Jul 2008 ...

We placed a DXM-eluting, polyurethane-covered, self-expanding metallic stent (drug stent, DS) and a polyurethane-covered, self-expanding metallic stent (control stent, CS) alternately in each left main bronchus and left lower lobe bronchus in 12 dogs. The stents were 20 mm in diameter and length when fully expanded. The dose of DXM was approximately 36.7 mg in each DS, but was absent in the CS. The dogs were euthanased 1 week ...
The third case of a culturally and histologically proven candidosis of the prostate in the world literature available to us is reported. Autopsy of a 59-year-old man with metastasizing bronchial carcinoma as predisposing primary disease revealed a local candidosis of the prostate in the left lobe of the prostate, without evidence of a Candida sepsis. Parallel and different aspects in comparison with the other two cases are described.

Endobronchial cancer are characterized by small size, slow growth and usually misdiagnosed as asthma or chronic bronchitis due to their common symptoms.This research report analyzes this market on the basis of its market segments, major geographies, and current market trends.
For operable patients with NSCLC in whom tumour growth is limited to one lobe, lobectomy is the treatment of choice. Intentionally curative radiotherapy is a good alternative if the surgical risk is determined to be (too) high.. Patients in whom lung function is so limited that lobectomy is not possible may be considered for segment resection (preferred) or wedge excision if complete resection using this method is possible.. In principle, if the lung tumour has spread from one lobe to another, a lobectomy plus a wedge resection of the other lobe should be performed. For central tumours, bilobectomy or pneumonectomy may be an option.. If a conventional lobectomy is not possible due to tumour growth up to or past the level of the bronchial ostium, a sleeve lobectomy is advisable because complete resection is possible with this technique even when lung function precludes pneumonectomy.. A sleeve resection of the pulmonary artery should be performed only if the patient cannot tolerate pneumonectomy ...

Arguably the simplest way to achieve one-lung ventilation is through deliberate bronchial intubation with a standard endotracheal tube. If this is used as a blind technique, the tube is most likely to go down the right main bronchus, as the course of the right main bronchus is more in line with the trachea than the course of the left, which comes off at the carina at a bigger angle.. [drawing]. This technique has several drawbacks: When a standard ETT is used to intubate the right main bronchus, the tube cuff is very likely to occlude the right upper lobe bronchus. So in addition to isolating the left lung this technique can inadvertently also isolate a significant part of the right lung. A second disadvantage is that left main bronchus intubation is not reliably achieved when this technique is used blindly. A fiberoptic scope is therefore frequently necessary to place a tube into the left main bronchus.. ...
In recent years, high flow nasal cannula is being increasingly used. Most studies showed positive results when used in hypoxaemic respiratory failure. Its use in a patient with a large endobronchial mass has not yet being described. We report a patient who presented with hemoptysis and hypoxaemic respiratory failure second to a large mass obstructing the right main bronchus. High flow oxygen via nasal cannula was initiated with a quick improvement of the hemoptysis and the oxygen saturation. Thus, allowing the patient to be rapidly stabilized.. ...
Progress in the field of fluorescence bronchoscopy has made it possible to locally diagnose bronchial dysplasia, thought sometimes to be the precancerous lesions of squamous cell carcinoma. We have recently reported the results of extensive studies of dysplasia in bronchial mucosa using white light bronchoscopy combined with fluorescence bronchoscopy.3 However, it proved impossible, even with a BF240 bronchovideoscope, to obtain findings other than swelling and redness in bronchial bifurcations, as previously reported.12,13 Because of the difficulty in diagnosing dysplasia by white light bronchoscopy, we attempted to obtain detailed white light observations of bronchial dysplasia using a direct viewing high magnification bronchovideoscope with the aim of developing a new method of bronchoscopic diagnosis.. In gastrointestinal endoscopy, high magnification endoscopy has been developed for observing and analysing epithelial microstructures. Moreover, there have been several recent reports on the ...
A 15-year-old boy presented to us with a 4-month history of fever with worsening dyspnea since 1 month. His contrast-enhanced computed tomography scan of the thorax showed bilateral endobronchial lesions with complete collapse-consolidation of the left lung and partial collapse of the right lower lobe. His fiberoptic bronchoscopy guided biopsy had been reported in outside hospital as a neuroendocrine tumor. Due to worsening breathlessness, he had to be intubated. We repeated the endobronchial biopsy and combined with outside slides and blocks, was diagnosed to have an anaplastic lymphoma kinase-1 positive anaplastic large cell lymphoma (ALCL ...
BACKGROUND: When hormones are detected in the serum of patients with bronchial carcinoma they are generally considered to originate from the tumour, but this may be not the only explanation. Pulmonary endocrine cells proliferate in lungs affected by non-neoplastic disease and their products are often demonstrable in the serum. The aim of this study was to examine the pulmonary endocrine systems of a series of tumour-bearing lungs to see whether any changes in them could possibly account for raised levels of pulmonary peptides in the blood. METHODS: The morphology, number, distribution, and content of pulmonary endocrine cells in 30 pairs of tumour-bearing lungs from patients coming to necropsy with bronchial carcinoma were examined. These features were related to the pathology of the tumour and to other pathological changes present in the lungs, and compared with pulmonary endocrine cells in 10 pairs of control lungs from patients without pulmonary disease. RESULTS: Increased numbers of ...
