Lung biopsy

Chad Dammling, Peter Waite, Tim Beukelman
Sarcoidosis is a multisystem granulomatous disease of unknown etiology that commonly affects the lungs, lymph nodes, and skin. The disease often presents in patients between the third and sixth decade and its pathology is defined by the presence of noncaseating granulomas within organs throughout the body. Oral and neurologic involvement of sarcoid is extremely rare and occurs in approximately 1% and 5% of patients with the disease, respectively. A case of sarcoidosis involving the gingiva and submandibular lymph nodes is described in a 14-year-old girl...

BACKGROUND: High serum neuron-specific enolase (NSE) level has been in use as a tumor marker; however, some physicians may ignore NSE levels in serum, especially when the patients are asymptomatic. Here we report a case that a 51 year old female patient with no respiratory symptoms who had a NSE level which increased extremely over three months and was eventually diagnosed small cell lung cancer (SCLC). METHODS: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in right pulmonary hilar enlarged lymph node was performed for diagnosis...

A 73-year-old Japanese man, who worked at a confectionery company for more than 20 years, was diagnosed with a 28 mm nodular lesion in the superior lobe of the right lung by whole-body computed tomography examination. A biopsy revealed the presence of adenocarcinoma. With a diagnosis of a primary lung cancer, a right upper lobectomy was performed. A nodular lesion, 25 × 23 mm in size, was observed in the upper right lobe lung field, and was diagnosed histopathologically as a papillary adenocarcinoma...

Histoplasmosis is a mycosis caused by the dimorphic fungus, Histoplasma capsulatum , which is transmitted via dust and aerosols. Lung involvement is the most common, with a varied clinical presentation. Although it is not the only source of infection, H. capsulatum is frequently found in bat guano, which is the reason why it is highly prevalent among caving practitioners. The solitary histoplasmoma of the lung is an unusual and chronic manifestation of this entity, which mimics, or at least is frequently misconstrued, as a malignancy...

High-grade endometrial carcinomas are aggressive neoplasms of difficult histological classification. Neuroendocrine differentiation in endometrial carcinomas is rare. This is the report of an endometrial large cell neuroendocrine carcinoma with foci of melanocytic differentiation in a 75-year-old woman with abnormal post-menopausal uterine bleeding for 2 years. Two initial biopsies were inconclusive. Histopathological examination of the uterus revealed large cell neuroendocrine carcinoma associated with endometrioid carcinoma and foci of melanocytic differentiation, pT3a (FIGO IIIA)...

Immune-checkpoint-inhibitors (ICPIs) represent a novel class of immunotherapy against several malignancies. These agents are associated with several "immune-mediated" adverse effects, but the reported renal toxicity of ICPIs is less well defined. We present the case of a 60-year-old man with a history of non-small cell lung cancer, who developed acute kidney injury (AKI) approximately 3.5 months after initiation of immunotherapy with nivolumab. Urinalysis revealed sterile pyuria, without microscopic hematuria or proteinuria...

Patients with advanced or metastatic forms of lung cancer with an activating mutation in epidermal growth factor receptor ( EGFR ) are given tyrosine kinase inhibitors (TKIs) targeted therapies that are more efficient than chemotherapy. These patients are excluded from first-line immunotherapy. After a phase of regression these tumors develop systematically resistance requiring a rapid change in therapy. At present two strategies are being discussed. The first strategy, so called "historical' sequential treatment strategy, is based on the administration of first- or second-generation TKIs until the emergence of therapeutic resistance and, in the case of a EGFR T790M mutation, on the administration of third-generation TKIs...

The list of theranostic biomarkers for the care of patients with advanced stage or metastatic non-small cell lung cancer has lengthened considerably these last few years. Moreover, the advances in therapeutics will certainly increase the number and complexity of these tests performed in laboratories in the near future. In addition, the methods for investigation of biomarkers that require access to biological tissue are less and less invasive with the consequential increase in the use of small-sized tissue biopsies and cytological and blood samples...

Growing evidences for tumor heterogeneity confirm that single-tumor biopsies frequently fail to reveal the widespread mutagenic profile of tumor. Repeated biopsies are in most cases unfeasible, especially in advanced cancers. We describe here how circulating tumor cells (CTCs) isolated from minimally invasive blood sample might inform us about intratumor heterogeneity, tumor evolution and treatment resistance. We also discuss the advances of CTCs research, most notably in molecularly selected non-small cell lung cancer (NSCLC) patients, highlighting challenges and opportunities related to personalized therapy...

Background: Prognostic evaluation in idiopathic pulmonary fibrosis (IPF) may be important as it can guide management decisions, but the potential role of honeycomb changes in providing information about outcome and survival of patients with IPF, particularly if diagnosed using cryobiopsy, has not been evaluated. Aim of this study was to determinate whether a relationship exists between honeycombing on cryobiopsy and clinical/radiological picture and outcome in patients with IPF and to assess whether the same pathologic criteria that have been used to define the UIP pattern (usual interstitial pneumonia) for surgical biopsy can also be applied to cryobiopsy...

BACKGROUND: Improved understanding of lung transplant disease states is essential because failure rates are high, often due to chronic lung allograft dysfunction. However, histologic assessment of lung transplant transbronchial biopsies (TBBs) is difficult and often uninterpretable even with 10 pieces. METHODS: We prospectively studied whether microarray assessment of single TBB pieces could identify disease states and reduce the amount of tissue required for diagnosis...

BACKGROUND Pituitary gland metastasis is rarely the initial presentation of metastatic cancer. Most cases of pituitary gland metastasis are asymptomatic with diabetes insipidus being the most common symptomatic presentation. It can rarely present with symptoms of hormone underproduction such as secondary adrenal insufficiency. Although pituitary gland metastasis is rare, it is underestimated, as it is commonly misdiagnosed with pituitary gland adenoma due to the lack of clear radiological criteria differentiating between both...

BACKGROUND: Intracranial vascular infections of fungal etiology are extremely rare. The vast majority of cases occur in immunocompromised patients with invasive fungal disease, most commonly originating in the paranasal sinuses or the lungs. An extremely rare type in this part of the world, called Granulomatous Invasive Rhinosinusitis, has been reported to affect immunocompetent patients in most cases, and its causative strain has potential to invade the intracranial arteries. CASE DESCRIPTION: We present a rare case of basilar artery rupture and infarction secondary to granulomatous invasive rhinosinusitis in a 50 year old male who presented with ischemic symptoms and 6 month history of headache, dizziness and falls in Florida, USA...

Multiple biomarkers are under evaluation to guide the use of immune checkpoint inhibitors in non-small-cell lung cancer (NSCLC), including programed death ligand 1 (PD-L1) tumor cell staining. We have developed a new approach that accurately quantifies PD-L1 status and identifies multiple mutations by using a single bronchoscopy specimen. A novel molecular marker was identified to detect the presence of malignant cells in radial endobronchial ultrasound bronchial brushings from NSCLC (n = 15) and benign (n = 13) nodules by quantitative real-time RT-PCR (RT-qPCR)...

OBJECTIVE: Using a hydrogel plug decreases the number of cases of pneumothorax and reduces the need for pleural drainage tubes in CT-guided lung biopsies. We aimed to analyze the cost-effectiveness of using hydrogel plugs. MATERIAL AND METHODS: We analyzed 171 lung biopsies divided into three groups: Group 1 (n=22): fine-needle aspiration cytology (FNAC) without hydrogel plugs; Group 2 (n=89): FNAC with hydrogel plugs; and Group 3 (n=60): FNAC plus core-needle biopsy (CNB) with hydrogel plugs...

OBJECTIVE: Lysyl oxidase (LOX) is an extracellular enzyme that cross-links collagen fibrils. LOX was found to be increased in serum of SSc patients and was suggested to be related to skin fibrosis, yet a vascular source of LOX has been demonstrated in idiopathic pulmonary arterial hypertension (iPAH). We aimed to validate elevated LOX serum levels in SSc and to study its correlation with clinical characteristics and investigate its main source at the tissue level. METHODS: A total of 86 established SSc patients were compared with 86 patients with very early diagnosis of systemic sclerosis (VEDOSS), 110 patients with primary RP (PRP) and 80 healthy controls...

BACKGROUND: Stereotactic ablative body radiotherapy (SABR) is widely used to treat inoperable stage 1 non-small-cell lung cancer (NSCLC), despite the absence of prospective evidence that this type of treatment improves local control or prolongs overall survival compared with standard radiotherapy. We aimed to compare the two treatment techniques. METHODS: We did this multicentre, phase 3, randomised, controlled trial in 11 hospitals in Australia and three hospitals in New Zealand...

Anaplastic large-cell lymphoma (ALCL) is a very rare but life-threatening complication that has largely been demonstrated to be associated with breast implants (BIA-ALCL). Patients are at risk of BIA-ALCL with the placement of breast implants for either cosmetic or reconstructive purposes, with the highest risks associated with textured breast implants. In the past decade, there have been an increasing number of publications focused on BIA-ALCL, but there has yet to be a reported case outside of the breast...

BACKGROUND: Pulmonary carcinoids are included in the group of neuroendocrine tumors (NET) and derive from pulmonary neuroendocrine cells. The incidence of these tumors is increasing, but disease awareness remains low among clinicians. The synchronous presentation of lung cancer and mycobacterial infection is well known but the combination of pulmonary carcinoid and mycobacterial infection is rare. CASE PRESENTATION: We treated a 45-year-old female who presented with recurrent pneumonia...
