Extension of metastatic lung tumors into the left atrium via pulmonary veins is rare. Here, we report the first case of Ewing sarcoma exhibiting such extension. A 31-year-old man with pulmonary metastasis from Ewing sarcoma presented with a mass in the left lung, extending to the left atrium through the left inferior pulmonary vein. As the patient was considered to be at risk of tumor embolism,...

BACKGROUND Merkel cell carcinoma is a high-grade neuroendocrine carcinoma of skin that is characterized by immature cells which, because of its striking morphologic similarity, may be confused with other small round blue cell tumors such as pulmonary small cell carcinoma or lymphoblastic leukemia/lymphoma. Immunohistochemistry is therefore paramount to ensuring accurate diagnostic distinction b...

patients with pulmonary cavities are usually exposed to other pulmonary infections, especially of fungus origin, such as asnprgillosis and coccidiomycosis. they are manifested by the formation of fungus ball in these cavities, which is completely resistant to anti-fungal therapy. in these circumstance the best method of treatment is removing of the ball by surgery, in this paper a case of pulmo...

BACKGROUND AND OBJECTIVE Cardiopulmonary bypass (CPB) in the treatment of locally advanced pulmonary malignant tumors invaded heart or great vessels was not well underwent. The aim of this study is to report the results of these cases with locally advanced pulmonary malignant tumor which were completely resected under CPB in our hospital. METHODS Four patients with locally advanced pulmonary ...

The electrical impedance of a pulmonary mass was measured in 53 patients of whom 44 had primary lung cancer, 5 had metastatic lung tumor, and 4 had organizing pneumonia. Because biologic tissue can be regarded, electrically, to consist of extracellular resistance (Re), intracellular resistance (Ri), and the electrical capacitance of the cell membrane (Cm), these three parameters were calculated...

PURPOSE To retrospectively evaluate the efficacy and safety of computed tomography (CT)-guided percutaneous interstitial brachytherapy using 125I radioactive seeds for multiple pulmonary metastatic tumors. MATERIAL AND METHODS Between September 2013 and December 2015, 22 patients with multiple pulmonary metastases, who after conventional chemotherapy and trans-arterial chemoembolization (TACE...

OBJECTIVE To report the efficacy and safety of CT-guided percutaneous laser ablation (PLA) for metastatic lung tumors. METHODS Three cases of metastatic lung cancer underwent CT-guided PLA, and we searched for previously published articles on the minimally invasive CT-guided RFA or MWA for lung tumors in recent five years. RESULTS With the guidance of CT, all lesions had good prognosis unde...

Neuroblastomas and Wilms' tumors are frequent pediatric solid tumors. The first is frequently detected in the adrenal gland and the second develops in the kidneys. The extension through the vena cava and the lung metastases are frequent in Wilms' tumors and are rarely seen in neuroblastoma. We present the cases of three children with abdominal tumors with thrombus in the inferior vena cava and ...

BACKGROUND Phosphatase and tensin homolog on chromosome ten (PTEN) is one of the most frequently inactivated tumor suppressors in various tumor types. MicroRNA-21 (miR-21) may affect tumor progression by post-transcriptional repression of expression of tumor suppressors, such as PTEN. This study was conducted to evaluate the significance of PTEN expression in pulmonary neuroendocrine (NE) tumor...

a case of pleomorphic adenoma in sweat gland is reported here. the histopathologic report confirmed the diagnosis. pleomorphic adenoma is most common in salivary glands but very rare in sweat glands. pleomorphic adenoma in sweat gland and the similar tumors of eccring sweat gland are described that bear a striking resemblance to pleomorphic adenomas of salivary gland. upon closer examination, t...
