Lymphangioleiomyomatosis (LAM) is a rare and progressive neoplastic disease of young woman, characterized by the proliferation of abnormal smooth muscle-like cells (LAM cells) in the lungs and axial lymphatics. A 44-year-old woman was referred to our hospital because pleural effusion was detected during a health checkup. She had chylothorax, chylous ascites, and chyluria, and her computed tomography scan showed a solid tumor in the pelvis. Surgical biopsy was performed; she was diagnosed as having LAM. We could not control the fluid collection and chyluria using standard medical treatments...

Background: Leptomeningeal metastases (LM) are more frequent in non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) mutations. Due to limited access to leptomeningeal lesions, the purpose of this study was to explore the potential role of cerebrospinal fluid (CSF) as a source of liquid biopsy in patients with LM. Patients and methods: Primary tumor, CSF, and plasma in NSCLC with LM were tested by next-generation sequencing. In total, 45 patients with suspected LM underwent lumbar puncture, and those with EGFR mutations diagnosed with LM were enrolled...

Coccidioidomycosis causes significant morbidity in endemic areas. In the absence of sensitive diagnostic serologic testing, clinicians have increasingly relied on lung and lymph node biopsies for diagnosis. Recently, endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) has been shown to be an excellent sampling method for the diagnosis and staging of lung cancers, especially when combined with endoscopic ultrasound guided fine needle aspiration (EUS-FNA). We present 13 consecutive cases where EBUS-TBNA and/or EUS-FNA of pulmonary lymph nodes were performed as part of the workup for pulmonary coccidioidomycosis...

A 52-year-old man developed interstitial pneumonitis during treatment with desvenlafaxine for major depressive disorder. The man received desvenlafaxine at 50 mg for symptoms of depression 4 years earlier. Six months after a dose increase to 100 mg, he developed bronchitic symptoms with mild, persistent dyspnea. Investigations revealed a restrictive pattern on pulmonary function testing, bilateral upper lobe reticular opacities with traction bronchiectasis on radiology imaging, and end-stage interstitial fibrosis with honeycomb changes consistent with chronic hypersensitivity pneumonitis on open lung biopsy...

Availability of tumor and non-tumor patient-derived models would promote the development of more effective therapeutics for Non Small Cell Lung Cancer (NSCLC). Recently, conditionally reprogrammed cells (CRC) methodology demonstrated exceptional potential for the expansion of epithelial cells from patient tissues. However, the possibility to expand patient-derived lung cancer cells using CRC protocols is controversial. Here, we used CRC approach to expand cells from non-tumoral and tumor biopsies of patients with primary or metastatic NSCLC as well as pulmonary metastases of colorectal or breast cancers...

Immune checkpoint inhibitors (ICIs) have demonstrated efficacy against various types of cancers. In addition to immune-related adverse events (irAEs) induced by ICIs, exacerbation of baseline autoimmune disease has been occasionally reported. This is the first report of autoimmune hemolytic anemia (AIHA) exacerbated by pembrolizumab. An 82-year-old Japanese male was diagnosed with lung adenocarcinoma 2 years ago. The patient had chronic anemia with positive direct and indirect Coombs test prior to initiating pembrolizumab therapy at a nearby hospital...

Eosinophilic granulomatosis with polyangiitis is a systemic vasculitis. It could affect respiratory system, kidney, and central nervous system frequently; however, all body organs could be involved. Asthma and eosinophilic pneumonia are predominant manifestations in respiratory system. Bronchoalveolar lavage or lung biopsy may be used for diagnosis, but endobronchial lesion is not considered as a manifestation of eosinophilic granulomatosis with polyangiitis. Here we present a case of eosinophilic granulomatosis with polyangiitis with unusual endobronchial lesion which was confirmed by endobronchial biopsy...

BACKGROUND: Asthma has been associated with increased collagen deposition in both conducting airways and alveolar parenchyma. Mast cells (MCs) are key effector cells in asthma, and have the ability to affect collagen synthesis. However, the link between clinical control and changes in bronchial and alveolar MC phenotypes and specific collagens in controlled and uncontrolled asthma remains unknown. OBJECTIVE: To investigate MC phenotypes in correlation to deposition of specific collagen subtypes in patients with controlled and uncontrolled asthma as well as to healthy controls...

Insufficient chemotherapy response and rapid disease progression remain concerns for small-cell lung cancer (SCLC). Oncologists rely on serial CT scanning to guide treatment decisions, but this cannot assess in vivo target engagement of therapeutic agents. Biomarker assessments in biopsy material do not assess contemporaneous target expression, intratumoral drug exposure, or drug-target engagement. Here, we report the use of PARP1/2-targeted imaging to measure target engagement of PARP inhibitors in vivo. Using a panel of clinical PARP inhibitors, we show that PARP imaging can quantify target engagement of chemically diverse small molecule inhibitors in vitro and in vivo...
