Pulmonary lymphangitic carcinomatosis is the spread of a tumor to the lungs through the lymphatic system, which is a rare and final manifestation of cancer with a poor prognosis. Its main symptom is gradual and progressive dyspnea. The method of choice for diagnosis is high-resolution CT (HRCT), the most common finding of which is an increase in nodular and irregular septal thickness between th...
An asymptomatic 71-year-old man was admitted for evaluation of a pulmonary tumor. Chest computed tomography revealed a cavitary tumor in the apical segment of the right lung. Histopathological examination of the resected lung revealed pulmonary cryptococcosis within a papillary adenocarcinoma. Macroscopic and histopathological findings speculated that papillary adenocarcinoma preceded pulmonary...
Asthma, chronic obstructive pulmonary disease (COPD), and pulmonary tuberculosis (TB) are common pulmonary diseases associated with lung cancer. Besides, smoking is more prevalent in Taiwanese men. This study evaluated gender disparities in coexisting pulmonary diseases on survival of patients with lung adenocarcinoma. Patients newly diagnosed with lung cancer between 2003 and 2008 were identif...
BACKGROUND Plasminogen activator inhibitor type 1 (PAI-1), an important regulator of plasminogen activator system which controls degradation of extracellular membrane and progression of tumor cells, and PAI-1 gene polymorphic variants have been known as the prognostic biomarkers of non-small cell lung cancer patients. Recently, experimental in vitro study revealed that transforming growth facto...
Nuclear localization of B7-H4 in pulmonary adenocarcinomas presenting as a solitary pulmonary nodule
PURPOSE Although the pathogenicity of B7-H4 in cancer is well established, its role in pulmonary adenocarcinoma, especially lesions presenting as solitary pulmonary nodules (SPNs), remains unclear. METHODS 40 cases of pulmonary adenocarcinoma presenting with SPN were enrolled during year 2012-2015. The B7-H4 expression and its subcellular distribution in pulmonary adenocarcinoma presenting wi...
Extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue type (extranodal MZL) is a distinct subgroup of non-Hodgkin's lymphoma. Pulmonary extranodal MZL is a rare entity and accounts for less than 0.5% of primary pulmonary malignancies. Only a few cases of simultaneous occurrence of lung cancer and pulmonary extranodal MZL have been reported. A 60-year-old woman was referr...
Reactive perforating collagenosis is one of the perforatingdermatoses; the acquired form is characterized by transepithelialelimination of altered collagen bundles. It has been seen inassociation with multiple disorders including diabetes mellitus,renal failure, hyperparathyroidism, liver disease, neurodermatitis,IgA nephropathy, and periampullary carcinoma with jaundice.According to the litera...
Ovine pulmonary adenocarcinoma (OPA) was studied in the lungs of 15 naturally-affected sheep (9 with classical and 6 atypical lesions) by transmission electron microscopy. Two lung samples from normal sheep were used to develop the ultrastructural criteria. Pathologic lesions consisted of focal-multifocal to coalescent nodules or masses in the cranioventral or diaphragmatic lobes. Ultrastructur...
Birt-Hogg-Dubé syndrome (BHD) is an inherited disorder caused by genetic mutations in the folliculin (FLCN) gene. Individuals with BHD have multiple pulmonary cysts and are at a high risk for developing renal cell carcinomas (RCCs). Currently, little information is available about whether pulmonary cysts are absolutely benign or if the lungs are at an increased risk for developing neoplasms. He...
