Various types of mediastinal masses or tumors can be seen in the mediastinum. Materials and Methods:This case series study was performed on 95 patients who had referred to Mashhad University of Medical Sciences between 1990 and 2010 were reviewed. The Inclusion cr...

A prospective study was conducted at the OB/GYN department of Kasr El Eini hospital, Cairo University from Jan 2000 - Oct 2002. The study included 51 patients in the age group between 40-70 years (including pre and post menopausal women). All patients were subjected to following after taking a consent from each patient: Complete clinical evaluation; including history taking and clinical examina...

From March 1980 to March 1989 a total number of 2254 (7.6%) new malignant cases from Kerman province were diagnosed by examination of surgical specimens, blood films and bone marrow smears. The crude relative frequency of cancers was studied and compared with other areas of Iran. Gastric (11.36%) and urinary bladder (7.01 %) carcinomas were significantly more common in Kerman province than...

introduction:neurogenic mediastinal tumors comprise a wide range of benign and malignant diseases. a group of these tumors, located at thoracic apex, sometimes spread to cervical spaces causing numerous surgical difficulties. in thoracotomy approaches, due to proximity of the tumors to major blood vessels, complete removal of these tumors from cervical spaces is impossible or may cause intraope...

neuroendocrine tumors are most often located in the intestine and lungs but they can arise from other areas of the body. limited data is available on epidemiology and clinical patterns of neuroendocrine tumors in iran. we analyzed medical records of 34 patients from 2 cancer centers (emam khomeini hospital and omid charity cancer center) in west azarbaijan province of iran with neuroendocrine t...

Intracranial hemangiopericytomas (HPC) are rare vascular tumors. They account for 0.4% of primary central nervous system tumors.

Background and objectives: Modeling cancer in vivo is a very important tool to investigate cancer pathogenesis and molecular mechanisms involved in cancer progression. Laboratory mice are the most common animal used for rebuilding human cancer in vivo. Cancer stem cells (CSCs) are the main reason of failure in cancer therapy because of tumor relapse and metastasis. Isolation of cancer stem cell...
