Peripheral T cell lymphoma not otherwise specified (PTCL-NOS) is a rare entity of lymphoma. We herein report an even rarer case of a 68-year-old male with PTCL-NOS presenting as an endobronchial lesion, and review previously published cases in the literature. Initially, he was referred to our hospital for further investigation of the right upper lobe consolidation on chest radiograph. Computed tomography and 18F-fludeoxyglucose positron emission tomography revealed a right hilar mass with obstruction of the main bronchus and submandibular, right axillary and mediastinal lymphadenopathy...

Large cell carcinoma (LCC) of the lung has a rapid mean volume doubling time (VDT) of around 67-134 days. In some cases of LCC where the VDT is extremely rapid, clinical presentation may mimic acute lung pathologies such as pneumonia. We describe a rare presentation of an aggressive LCC of the lung with an estimated VDT of around two weeks. A 52-year-old male with a history schizophrenia presented with fever, cough, and dyspnea for three weeks duration. His medical history was significant for a recent admission six weeks before current presentation for myocardial infarction (MI) and pneumonia...

We report a very rare case of pulmonary chromomycosis caused by Scedosporium prolificans that developed after lung transplantation and was successfully treated with endobronchial topical amphotericin B instillation. The subject was a woman in her 50s with a history of bilateral lobar lung transplantation from living donors for idiopathic pulmonary hypertension. Eight years after the lung transplantation, chest radiography X-ray and computed tomography showed an abnormal shadow in the right lung. Bronchoscopic findings showed obstruction by a fungal component at the laterobasal bronchus B9...

BACKGROUND: Asthma and chronic obstructive pulmonary disease (COPD) are chronic conditions with an increasing prevalence in developing countries. The evaluation of endobronchial biopsies has emerged as a tool to differentiate between both conditions via the measurement of the reticular basement membrane (RBM) thickness with various conclusions drawn from different studies. OBJECTIVES: Compare the thickness of the RBM between asthma and COPD and evaluate other histomorphological features in both groups...

BACKGROUND: Germline mutations in the tumour suppressor gene CYLD are recognised to be associated with the development of multiple cutaneous cylindromas. We encountered such a patient who presented with breathlessness due to multiple pulmonary cylindromas. OBJECTIVE: Patients with rare genetic diseases are poorly studied, so we searched for clinical and radiological features of multiple pulmonary cylindromas in a cohort of 16 patients with CYLD mutations. METHODS: A retrospective case note review was carried out in a tertiary dermatogenetics clinic where CYLD mutation carriers are reviewed on an annual basis...

We report a case of Hodgkin's lymphoma presenting as an endobronchial mass in a 40-year-old man with history of 8 months of non-specific symptoms like cough, fatigue and weight loss. Initially he was treated with broad-spectrum antibiotics for suspicion of pneumonia without recovery. Radiographic work-up showed cavitary consolidation of the upper lobe of the left lung, followed by bronchoscopy which showed obstructing mass of the upper lobe of the left lung mimicking primary lung carcinoma. Immunohistochemical staining of the specimen was suggestive of Hodgkin's lymphoma...

A 71-year-old man, who had received long-term oxygen therapy for respiratory failure caused by chronic obstructive pulmonary disease, had an enlarged mediastinal lymph node for one year. As his lung function was poor, we tried performing endobronchial ultrasound-guided transbronchial needle aspiration under non-invasive positive pressure ventilation for diagnosis but could not obtain sufficient specimens. Later, we performed an endoscopic ultrasound with bronchoscope-guided fine-needle aspiration (EUS-B-FNA) using a transesophageal approach...

Bronchial stenosis is known to complicate endobronchial tuberculosis despite medical therapy. It is often associated with dyspnoea. In severe cases, bronchial stenosis results in airflow obstruction, impaired secretion clearance, and can lead to respiratory failure. We present an unusual observation of platypnoea-orthodeoxia syndrome in a young woman with acute atelectasis due to post-tuberculosis bronchial stricture. Imaging revealed complete middle and right lower lobe atelectasis with a partially aerated right upper lobe...

Endoscopic lung volume reduction is a minimally invasive procedure performed to reduce the space occupied by the emphysemas' lobes. This procedure has been demonstrated to be beneficial for patients with advanced chronic obstructive pulmonary disease and severe hyperinflation. The use of endobronchial valves is increasing, as well as the number of reports of adverse events. The most common complications after the procedure are a pneumothorax, bleeding, infections, the need for valve removal, and valve expulsion...

REVIEW

Since the publication of the National Emphysema Treatment Trial study, lung volume reduction (LVR) has been considered a therapeutic alternative for patients with advanced obstructive lung disease. The high complication rate of surgical LVR has led to the development of bronchoscopic LVR (BLVR). Of the currently available BLVR alternatives, coils and unidirectional endobronchial valves lead the list. The choice of each device depends on emphysema characteristics and presence of collateral ventilation. Evaluation of these patients at centers with expertise in interventional pulmonology and management of BLVR is strongly recommended...

Mucociliary clearance is a biomechanical mechanism of airway protection. It consists of the active transport along the bronchial tree of the mucus, a fluid propelled by the coordinated beating of a myriad of cilia on the epithelial surface of the respiratory tract. The physics of mucus transport is poorly understood because it involves complex phenomena such as long-range hydrodynamic interactions, active collective ciliary motion, and the complex rheology of mucus. We propose a quantitative physical analysis of the ciliary activity and mucus transport on a large panel of human bronchial cultures from control subjects, patients with asthma and chronic obstructive pulmonary disease obtained from endobronchial biopsies...

OBJECTIVES: This study was designed to establish a porcine model of reversible obstruction of endobronchial foreign body (FB) and to assess the natural pulmonary reexpansion process using radiology and histopathology after removal of the bronchial FB. METHODS: A metal stent was placed in the right lower lobe bronchial lumen of 15 pigs by bronchoscopy and removed after 2 weeks of stent retention. Animals were divided into two groups (group I and II), based on when they were sacrificed (week 2 or week 4) after stent removal...

Female, 85 y.o., weighting 60kg, multiple trauma patient. After an initial laparotomy, an emergent thoracotomy was performed using a bronchial blocker for lung isolation (initial active suction was applied). During surgery, bronchial cuff was deflated, causing a self-limited tracheal blood flooding. A second lung isolation was attempted but it was not as effective as initially. Probably, a lung collapse with the same bronchial blocker was impaired in the second attempt because of the obstruction of bronchial blocker lumen by intraoperative endobronchial hemorrhage...

Endobronchial obstruction is a known cause of an unexpandable lung. Endobronchial lesions are usually malignant, however benign cause like hemartoma, lipoma, amyloidosis and neuroendocrine tumors are known. We, hereby present the rare cause of bronchial elastosis presenting as right lower lobe lung collapse.

An 11-month-old healthy infant girl was noted to have left lower lobe (LLL) opacities on chest X-ray (CXR) after developing desaturations during an elective cochlear implant surgery. Repeat CXR 10 days later revealed hyperexpansion of the left lung and persistent LLL opacity. Chest computerized tomography revealed enlarged mediastinal lymph nodes, left mainstem bronchial obstruction, and nodular opacities. Bronchoscopic biopsy of the endobronchial tissue revealed multiple necrotizing granulomas and grew Mycobacterium avium-intracellulare , Streptococcus viridans , and Actinomyces odontolyticus ...

Retained foreign bodies within the stomach and proximal small bowel may be problematic in patients with prior cerebrovascular injury or head, neck and esophageal malignancy, given the increased vulnerability of this patient population to complications from aspiration and increased difficulty of esophagogastroduodenoscopy in cases of tumoral obstruction. This article presents an alternative method for foreign body retrieval through an existing gastrostomy tract, which offers the benefits of fast procedure times, reduction in radiation dose and fluoroscopy time, and allows for safer retrieval of foreign bodies by using direct visualization...

A case of tracheobronchial stenosis due to tuberculosis in a young woman is presented. Compromised pulmonary function due to near-total obstruction of the proximal left main bronchus was diagnosed. Treatment options included surgical resection, endobronchial dilation or stenting, and argon photocoagulation. An approach was chosen to address symptoms without aggressive resection or commitment to stenting. She remains monitored and, while possibly committed to future intervention, no bridges have been burned with respect to more definitive and invasive therapies...

We present here a 47-year old male patient who had a typical carcinoid tumor located at the orifice of right lower lobe bronchus underwent uniportal thoracoscopic lower lobectomy following bronchoscopic removal of the endobronchial tumor. Tumor was seen by bronchoscopy to protrude out from the lower lobe into the intermediary bronchus obstructing the lower lobe completely and the middle lob partially. However, the origin of the endobronchial tumor was in the distal part of the lower lobe bronchus. In this case, open surgery could be an alternative to save the middle lobe by incising the lower lobe bronchus to pull out the endobronchial tumor first during thoracotomy...

Primary pulmonary tuberculosis can involve regional lymph nodes which may resolve spontaneously or on treatment; or they may enlarge causing extrinsic bronchial compression; or cause endobronchial inflammation and ulceration; or a node may erode through the bronchial wall with extrusion of caseous materials into the bronchial tree, causing focal or lobar pneumonia. This erosion is seen radiologically as hilar lymphadenopathy, with atelectasis and consolidation and described as "epituberculosis". It is more common in infants than older children...
