BACKGROUND: With the release of the National Lung Screening Trial results, the detection of peripheral pulmonary lesions (PPLs) is likely to increase. Computed tomography (CT)-guided percutaneous transthoracic needle biopsy (PTNB) and radial probe endobronchial ultrasound (r-EBUS)-guided transbronchial lung biopsy (TBLB) are recommended for tissue diagnosis of PPLs. METHODS: A systematic review of published literature evaluating the accuracy of r-EBUS-TBLB and CT-PTNB for the diagnosis of PPLs was performed to determine point sensitivity and specificity, and to construct a summary receiver-operating characteristic curve...

BACKGROUND: Systemic sclerosis (SSc) is a multi-organ autoimmune disease characterized by skin fibrosis. Internal organ involvement is heterogeneous. It is unknown whether disease mechanisms are common across all involved affected tissues or if each manifestation has a distinct underlying pathology. METHODS: We used consensus clustering to compare gene expression profiles of biopsies from four SSc-affected tissues (skin, lung, esophagus, and peripheral blood) from patients with SSc, and the related conditions pulmonary fibrosis (PF) and pulmonary arterial hypertension, and derived a consensus disease-associate signature across all tissues...

BACKGROUND: The metastases of a primary lung cancer over the thyroid gland are extremely rare. We report on an unusual presentation of thyroid metastasis of lung cancer in order to improve the management of similar cases. CASE PRESENTATION: Three years ago, a Moroccan male 59-year-old was admitted for dyspnea, dry cough, and chest pain. He had smoked about 30 cigarette packs a year. Clinical examination revealed a right thyroid nodule. Chest and neck computed tomography (CT) scan showed a proximal left tumor in contact with the pulmonary artery and revealed a suspected nodule in the right lobe of the thyroid with homolateral neck node...

A young patient from central Africa presented acute renal insufficiency due to extrinsic compression of the distal ureters by a pelvic mass. After initial medical management, a biopsy revealed poorly differentiated bladder cancer and Schistosoma haematobium eggs embedded in the bladder wall. The initial workup showed evidence of locoregional disease. Radical cystectomy with an incontinent urinary diversion was performed with no complications. Carcinosarcoma of the bladder was diagnosed by pathological analysis of the surgical specimen...

Thymic carcinoma is a rare cancer, accounting for only 1% to 4% of thymic epithelial tumors. Endobronchial metastasis is a rare presentation of these tumors. A 64-year-old man presented with a cough. Lung cancer was suspected because a chest radiograph showed a 7-cm mass in the left pulmonary hilum. Computed tomography showed a mass in the anterior mediastinum and an infiltrate in the upper lobe of the left lung. Bronchoscopy demonstrated bilateral polypoid tumors in the left B bronchus and the right B bronchus...

Eccentric ergometer training (EET) is increasingly being proposed as a therapeutic strategy to improve skeletal muscle strength in various cardiorespiratory diseases, due to the principle that lengthening muscle actions lead to high force-generating capacity at low cardiopulmonary load. One clinical population that may particularly benefit from this strategy is chronic obstructive pulmonary disease (COPD), as ventilatory constraints and locomotor muscle dysfunction often limit efficacy of conventional exercise rehabilitation in patients with severe disease...

Goodpasture's disease without circulating autoantibodies is a rare presentation of a rare diagnosis. We present the case of a man aged 17 years who had 3 hospital admissions over a 2-month period with haemoptysis and shortness of breath. Throughout his first 2 admissions, his renal function was normal and anti-glomerular basement membrane (GBM) antibodies were negative. CT pulmonary angiogram during his second admission revealed florid and diffuse alveolar infiltrates. However, high-resolution CT chest performed 4 weeks later showed complete resolution of these changes...

Immunoglobulin G4-related disease (IgG4-RD) is a recently defined condition characterized by inflammatory tumefactive lesions in various organ systems. IgG4-RD is a clinical and radiological diagnosis of exclusion and requires the presence of specific histopathological criteria for diagnosis. A 50-year-old man presented to an outside hospital with a 3-month history of progressively worsening back pain and symptoms of pleurisy, nasal crusting, and hematochezia. Radiological workup revealed an epidural-paraspinal mass with displacement of the spinal cord, destruction of the T5-6 vertebrae, and extension into the right lung...

BACKGROUND: Computed tomography-guided needle biopsy (CTNB) is a well-established and commonly used technique for diagnosing pulmonary nodules with high accuracy and safety. Needle-tract implantation after CTNB has been reported in various reports. The aim of this study is to evaluate whether preoperative CTNB affected the distant metastasis and overall survival in pathological stage I-II lung cancer patients. METHODS: A total of 1,234 patients with pathological stage I-II non-small cell lung cancer were collected...

BACKGROUND: Collision tumors are uncommon but well described clinical entities composed of distinct tumor histologies occurring within the same anatomic site. Optimal management of patients with collision tumors remains highly variable and depends on clinical characteristics such as the involved tumor types, predominant histology, as well as the extent of disease. Comprehensive genomic profiling is a means of identifying genomic alterations to suggest benefit from targeted therapy. CASE PRESENTATION: A 78-year-old woman presented to medical oncology with liver metastases occurring within the background of a 1-year history of uveal melanoma...

Graft failure represents a leading cause of mortality following organ transplantation. Acute late-onset graft failure has not been widely reported. This paper describes the demographics, CT imaging pathology findings and treatment of patients presenting with the latter. A retrospective review of lung transplant recipients at 2 large-volume centres was performed. Acute late-onset graft failure was defined as sudden onset of bilateral infiltrates with an oxygenation index <200 without identifiable cause or concurrent extra-pulmonary organ failure...

BACKGROUND: Bronchial asthma is a heterogeneous disease characterized by three cardinal features: chronic inflammation, variable airflow obstruction, and airway hyperresponsiveness. Asthma has traditionally been defined using nonspecific clinical and physiologic variables that encompass multiple phenotypes and are treated with nonspecific anti-inflammatory therapies. Based on the modulation of airway remodeling after 12 months of anti-immunoglobulin E (IgE) treatment, we identified two phenotypes (omalizumab responder, OR; and non-omalizumab responder, NOR) and performed morphometric analysis of bronchial biopsy specimens...

Polycythaemia vera (PV) is the most common myeloproliferative neoplasm, characterised by increased red cell mass that can present as an unspecified symptom or a thrombohaemorrhagic event. Its diagnosis is based on the presence of erythrocytosis, the identification of the Janus kinase 2 mutation and bone marrow aspirate or biopsy alterations. The challenge of this disease lies on the treatment approach. Its cornerstone is phlebotomy, but depending on the vascular risk, it can include cytoreductive agents, low-dose aspirin or even anticoagulation...

In daily practice, signet ring cell morphology immediately brings to the mind the possibility of an adenocarcinoma at first glance. The signet ring cell appearance has been described and is well-known in a wide variety of some other neoplasms as well. Surprisingly however, neoplastic cells having the same morphology can unexpectedly be encountered in not previously well-documented tumors. Here, we present an 85-year-old man diagnosed with primary pulmonary squamous cell carcinoma and a large signet ring cell population...

Cosmetic tattooing has become a risk factor for several adverse reactions related to inks, procedures, and associated clinical conditions. Development of a sarcoid reaction to the inserted tattoo pigment in the skin is not common. We report a 45 year-old patient with history of dyspnea and mild cough since two years who had subsequently developed reddish, scaly lesions in her 15-year old tattoo done near her right eyebrow. Skin biopsy of the tattoo lesion revealed cutaneous sarcoidosis which led to further investigations and a diagnosis of pulmonary sarcoidosis...
