Pulmonary tumor embolism rarely occurs in epithelial-derived tumors, but it has been described in different tumor entities. Microscopic pulmonary tumor embolisms are often only discovered on autopsy. Pulmonary thromboembolism, on the other hand, is a frequent complication in cancer patients, and surgery in patients with a malignant tumor is an additional risk factor. The differential diagnosis ...

Most meningiomas are benign; however anaplastic usually highly invasive and grow rapidly. These tumors can metastases outside the blood-brain barrier occurring to lungs. We present an unusual case of multiple pulmonary from recurrent intracranial meningioma in a 59-year-old male patient. Multiple very rare, but we should be aware this possibility patients with malignant especially, potential pr...

Introduction. Primary sarcomas are uncommonly seen in the larynx and comprise around 1% of all laryngeal malignant tumors. We present three cases patients with different types discuss about diagnostic treatment difficulties. Case outline. Each patient presented hoarseness shortness breath. Computed tomography scans showed large transglottic tumors no signs cervical lymphadenopathy definitive di...

Pulmonary sclerosing hemangioma is an uncommon benign tumor of the lung; however, on rare occasions it can arise from the pulmonary hilar region. Herein, we report a 53-year-old female patient who presented with a round opacity in the right upper lung field on a radiograph. Chest computed tomography scanning revealed a 3.1 cm mass in the right pulmonary hilum. Thoracoscopic tumor excision was s...

Purpose: This study aimed to investigate the expression of the ErbB family of receptor tyrosine kinases in pulmonary typical carcinoid and atypical carcinoid tumors and to understand the role of epidermal growth factor receptor (EGFR) signaling in pulmonary carcinoid tumor proliferation. Experimental Design: Surgically resected typical carcinoid (n = 24) and atypical carcinoid (n = 7) tumor tis...

Immunoreactivity for fascin, an actin-bundling protein related to cell motility, has been reported in breast, ovary, pancreas, skin, and non-small cell carcinomas, and associated with more advanced disease stage and poorer prognosis. Data on pulmonary neuroendocrine (NE) tumors, however, are lacking. We evaluated the expression of fascin by immunohistochemistry--using two different monoclonal a...

Gastrointestinal stromal tumors (GISTs) are rare tumors, with an estimated unadjusted incidence of around 1/100 000/ year [1]. It is a result of mutations in KIT tyrosine kinase and in platelet-derived growth factor receptor α (PDGFRA) [2,3]. These mutations are targeted by Imatinib Mesylate in the metastatic,adjuvant and neoadjuvant setting [4,5]. This drug blocks also the BCR-ABL tyrosine kin...

The assessment of patients with pulmonary focal abnormalities continues to represent an important problem in pulmonary diagnosis. A large number of lung nodules remains undetermined after bronchoscopy, radiological and CT imaging analysis. Ultrasound can contribute to the determination of the nature of peripheral lung tumors, serving as an important aid in decision-making. It helps the investig...

The diagnostic value of somatostatin receptor scintigraphy (SRS) in detecting tumors has been assessed in a number of studies. We present a 30-year-old female with a history of eight months cough and left shoulder pain. Radiologic evaluation showed pulmonary mass and hepatic lesions, which were pathologically diagnosed as neuroendocrine carcinoma. 99mTc-octreotide scan demonstrated that the pul...
