Background: Malignant pleural effusion is common in patients with advanced malignant tumor. The aim of this study is to analyze the characteristics of pleural metastasis of renal clear cell carcinoma, pleural effusion under medical thoracoscopy and the diagnostic value of interventional thoracoscopy-guided biopsy, and to improve the understanding of pleural metastasis of renal clear cell carcin...

Adenoid cyst carcinoma (ACC) is an uncommon facial tumor and challenging to treat; surgical treatment due its localization. A 49-year-old Latin female patient with a one-year history of soft tissue-depending mass slow growth in the right maxillary region. Laboratory tests reported normal. Contrast-enhanced computed tomography showed tumor. Patient underwent resection by Weber-Fergusson approach...

in this study esophageal resection and radiotherapy methods were compared in relation to the patients suffering from esophageal cancer. three hundred and fifty-four patients with squamous cell carcinoma of esophagus who had been hospitalized in the cancer institute of the imam khomeini hospital, tehran, during 1981-1985 were followed up through march 21st, 1987. based on the findings, patients ...

Gastric neuroendocrine carcinoma is a rare tumor which has a poor prognosis. Herein, we present a 55-year-old woman who presented with complaints of recurrent vomiting, hematemesis and weight loss. Endoscopic examination showed a large ulcerated mass in the antrum. Microscopic evaluation of the specimen taken through biopsy was compatible with a small round cell tumor. However, definitive histo...

Endoscopic resection of early gastric cancer is defined as incomplete when tumor cells are found at the resection margin upon histopathological examination. However, a tumor-positive resection margin does not always indicate residual tumor; it can also be caused by tissue contraction during fixation, by the cautery effect during endoscopic resection, or by incorrect histopathological mapping. C...

Congenital granular cell tumor (GCT) is a relatively rare intraoral benign tumor, approximately 200 cases of which have been reported in the neonatal period worldwide. The newborn infant may have feeding problems and respiratory difficulties due to airway obstruction. This lesion may be diagnosed by prenatal ultrasonography and simple resection is mostly required. We report a case of an adult t...

Tumor ablation is a minimally invasive approach commonly used in the treatment of liver tumors. Over last two decades, percutaneous radiofrequency (RFA) has been widely for primary tumors and small metastases, especially liver. Effective RFA can be accomplished by complete tumor accompanied margin resection at least 0.5 cm. One methods ablation. The overall disease-free survival rate was found ...

pheochromocytomas are cathecolamine producing tumor arising from chromaffin cells of adrenal medulla and extra adrenal tissues. this is a report of a boy presented with headache and hypertension. in radiologic exams, an adrenal mass detected in the left side, with no renal tissue on that side. it was reported an adrenal pheochromocytoma in histopathology. renal agenesis confirmed during surgery...

Abstract Glioblastoma (GBM) is the most aggressive type of brain cancer with no successful treatment available. Microglia makes up to 30% total GBM tumor mass. Previously we demonstrated that microglia within stimulate glioma cell growth and invasion through proline rich tyrosine kinase 2 (Pyk2). Tumor resection first line for GBM. Our previous studies use mouse implantation model indicate in a...
