A 55-year-old man experienced nausea and vomiting after brushing his teeth. He experienced back pain after this episode and visited our emergency department. Chest computed tomography (CT) images revealed moderate pleural fluid accumulation and mild left pneumothorax.

Prolonged COVID-19 in an Immunocompromised Patient Treated with Obinutuzumab and Bendamustine for Follicular Lymphoma.

A patient with follicular lymphoma treated with obinutuzumab and bendamustine experienced prolonged coronavirus disease-2019 (COVID-19). One month after the symptoms transiently improved, the patient experienced exacerbated COVID-19 symptoms. The patient recovered from COVID-19 with remdesivir and dexamethasone and was discharged 77 days after the disease onset.

Silica-associated systemic lupus erythematosus with lupus nephritis and lupus pneumonitis: A case report and a systematic review of the literature.

Introduction: Several epidemiological studies have shown that silica exposure triggers the onset of systemic lupus erythematosus (SLE); however, the clinical characteristics of silica-associated SLE have not been well studied.

Patient Concerns: A 67-year-old man with silicosis visited a primary hospital because of a fever and cough. His respiratory condition worsened, regardless of antibiotic medication, and he was referred to our hospital.

Rebiopsy with Thoracoscopy under Local Anesthesia for the Detection of EGFR T790M Mutation.

A 70-year-old woman underwent right upper lobectomy for adenocarcinoma of the lung (pT1bN2M0 stage IIIA). Five years after the surgery, lymph node recurrence was detected. Gefitinib was administered because epidermal growth factor (EGFR) exon 19 deletion mutation was detected in the previously resected surgical specimen.

Adenocarcinoma of the Lung Acquiring Resistance to Afatinib by Transformation to Small Cell Carcinoma: A Case Report.

A 65-year-old woman visited our hospital due to right chest pain and dyspnea on exertion. Chest radiography revealed decreased permeability of the right lung. Computed tomography demonstrated a huge mass in the right upper lobe and right pleural effusion.

Esophagobronchial Fistula in a Patient with Squamous Cell Carcinoma of the Lung: A Case Report.

A 73-year-old man was referred to our hospital after a 2-week history of bloody sputum and cough. Computed tomography (CT) images of the chest showed a mass grouped with mediastinal lymph nodes, and bronchoscopy showed a projecting mass in the right main bronchus. After a transbronchial biopsy, the patient was diagnosed with squamous cell carcinoma (T4N2M0 stage IIIB).

Angiosarcoma of the thoracic wall responded well to nanoparticle albumin-bound paclitaxel: A case report.

An 81-year-old woman visited a local clinic due to chest pain and a skin induration on the right precordia. She had a history of right breast cancer, and she had undergone a mastectomy and radiation therapy 10 years prior. Computed tomography (CT) imaging of the chest demonstrated a lobular mass that involved the right anterior thoracic wall and partially extruded from the thoracic cavity into the subcutaneous tissue.

Lymphoproliferative disorder in pleural effusion in a subject with past asbestos exposure.

Primary effusion lymphoma (PEL) is a subtype of non-Hodgkin lymphoma that presents as serous effusions without detectable masses or organomegaly. Here we report a case of PEL-like lymphoma in a patient with past asbestos exposure. A 65-year-old man was referred to our hospital due to dyspnea upon exertion.

Brain metastases in malignant pleural mesothelioma.

The brain is a rare site of metastasis in malignant pleural mesothelioma (MPM), and its clinical features and prognosis remain unclear. The aim of this study was to investigate the incidence, prognosis, and risk factors for brain metastases (BM) in MPM patients. Between July 1993 and October 2014, 150 patients with histologically proven MPM were included in this retrospective study.

Prognostic significance of the lymphocyte-to-monocyte ratio in patients with malignant pleural mesothelioma.

Objectives: Chronic inflammation plays a key role in the pathogenesis of malignant pleural mesothelioma (MPM) as a result of asbestos exposure. Several inflammation-based prognostic scores including the lymphocyte-to-monocyte ratio (LMR), Glasgow Prognostic Score (GPS), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) reportedly predict survival in many malignancies, while the role of LMR in MPM remains unclear. The aim of this study was to evaluate the clinical value of LMR and to compare the prognostic value of these inflammation-based scores in predicting overall survival (OS) in MPM.

Hyaluronic acid in the pleural fluid of patients with malignant pleural mesothelioma.

Background: We retrospectively analyzed hyaluronic acid (HA) concentrations in pleural fluid and evaluated its utility for the differential diagnosis of malignant pleural mesothelioma (MPM).

Methods: Pleural fluid HA concentrations were measured in 334 patients, including 50, 48, 85, 18, 86, 6, and 41 patients with MPM, benign asbestos pleurisy (BAP), lung cancer (LC), other malignant conditions (OMCs), infectious pleuritis (IP), collagen disease (CD), and other conditions, respectively.

Results: The median (range) HA concentrations in pleural fluid were 78,700 (7920-2,630,000)ng/ml in the MPM group, 35,950 (900-152,000)ng/ml in the BAP group, 19,500 (2270-120,000)ng/ml in the LC group, 14,200 (900-101,000)ng/ml in the OMC group, 23,000 (900-230,000)ng/ml in the IP group, 24,600 (9550-80,800)ng/ml in the CD group, and 8140 (900-67,800)ng/ml in the other diseases group.

Successful treatment with pemetrexed, Carboplatin, and bevacizumab for platinum-resistant adenocarcinoma of the lung.

WE PRESENT TWO CASES OF RELAPSED ADENOCARCINOMA OF THE LUNG: a 50-year-old male and a 67-year-old male. Both patients had previously been treated with platinum-containing systemic chemotherapy. In both cases, significant clinical efficacy was demonstrated with combination chemotherapy consisting of pemetrexed, carboplatin, and bevacizumab as salvage treatment.

Acute onset of brain atrophy and dementia in a patient with small cell lung cancer: a case report.

A 59-year-old man who was diagnosed with small cell lung cancer (SCLC), achieved a complete response to the induction chemoradiotherapy and received prophylactic cranial irradiation (PCI) (25 Gy at 250 cGy per fraction) in October 2008. Three months later, he complained of anorexia, weight loss, fatigue, and short-term memory loss and developed dementia and systemic muscle weakness. Magnetic resonance imaging in April and July 2009 revealed the progression of the diffuse brain atrophy without evidence of the metastasis of SCLC.

Soluble mesothelin-related protein in pleural effusion from patients with malignant pleural mesothelioma.

Malignant pleural mesothelioma (MPM) is a highly aggressive neoplasm primarily arising from surface serosal cells of the pleura and is strongly associated with asbestos exposure. Patients with MPM often develop pleural fluid as initial presentation. However, cytological diagnosis using pleural fluid is usually difficult and has limited utility.

Tuberculosis diagnosed by PCR analysis of synovial fluid.

Tuberculosis is a leading cause of mortality due to an infectious agent worldwide. It often affects multiple organs by hematogenous spread of Mycobacterium tuberculosis, but knee-joint involvement is extremely rare, comprising approximately 0.1% of all forms of tuberculosis.

[A case of miliary tuberculosis presenting with acute resiratory distress syndrome].

An 87-year-old woman was admitted because of high fever, progressive dyspnea and abnormal shadows on chest roentgenogram. Laboratory investigation on admission demonstrated a normal white cell count with neutrophilia (4000/microl, 90.5% neutrophils), an erythrocyte sedimentation rate of 10 mm/h and C-reactive protein value of 9.
