Chondrosarcoma is a common malignant bone tumor, which accounts for 20% of all malignant bone tumors. It often occurs in the long bones, but the incidence of scapular chondrosarcoma is rare. Here, we describe a case of a large chondrosarcoma occurring in the scapula which was treated with Malawer limb salvage surgery. The patient retained considerable limb function after complete removal of the...
Abstract Backgraound: Regarding the prevalence and high mortality rate of ovarian cancers, importance of markers to determine ovarian malignancies earlier, considerable experimental evidence about serum Gonadotropins to cyst fluid ratio with pathology of ovarian tumors and finally not enough experiments in our country, the present study was performed in Imam Hossein hospital between 2008 and...
malignant tumors of the oral cavity which are metastatic are very rare and consist of 1% of malignancies of the oral cavity. numbness or paresthesia of the lower lip or the chin is the main feature of presence of metastasis in the jaw. our patient was a 38 year old woman with chief complaint of pain in the right half of her face, jaw and teeth. her medical history revealed a radical mastectomy ...
GREM1 is a secreted protein that antagonizes bone morphogenetic proteins (BMPs) and participates in critical biological processes, including embryonic development, organogenesis tissue differentiation. Gremlin 1 (GREM1) also an inhibitor of TGF‑β ligand for vascular endothelial growth factor receptor 2. In addition, can induce cells, participate the process epithelial‑mesenchymal transition, th...
background: thromboembolism is the most important complication of cancers.the aim of this study was to determine d-dimer levels in benign and malignant tumors of the uterus, ovary and cervix. subjects and methods: this was a cross sectional study and it was conducted on 90 female patients referred to imam khomeini and arash hospitals because of uterine, cervical and ovarian tumors in 2013-2014....
background and aims. mast cells are one of the characteristic factors in angiogenesis, growth, and metastatic spread of tumors. the distribution and significance of mast cells in many tumors have been demonstrated. however, few studies have evaluated mast cell infiltration in salivary gland tumors. in this study, mast cell counts were evaluated in benign and malignant salivary gland tumors. mat...
We report two cases of cavernous hemangioma originating in the sinonasal cavity. Although CT showed some enhancing areas within both tumors, the substantial bone destruction caused by these tumors made it difficult to differentiate them from the more common malignant epithelial tumors. Angiography was performed in one patient and showed characteristic pooling of contrast material.
Introduction: Most common glioma tumors are tumors of the central nervous system (CNS) which are the cause of about 40 to 50 percent of brain tumors. This type of cancer includes 2 to 3 percent of cancers in the world. Conventional MRI is powerless in the detection and differentiation of benign and malignant tumors. In this case, diffusion weighted imaging (DWI) can create cont...
PURPOSE We have determined the ability of positron emission tomography (PET) with the thymidine analogue 3'-deoxy-3'[18F]fluorothymidine (FLT) to detect manifestation sites of bone and soft tissue tumors, to assess tumor grading, and to differentiate malignant from benign tumors. MATERIALS AND METHODS In this prospective bicenter trial, FLT-PET was done in 22 patients with established or susp...
