patients with malignancy are at higher risk of thrombotic complications due to the hypercoagulability state. our objective in this study was to assess the serum concentrations of homocysteine, anti phospholipid antibodies, and anti cardiolipin in patients with benign and malignant breast tumors and study the effect of chemotherapy on the serum levels of these markers. a case control study was c...

neuroendocrine tumors (nets) constitute a heterogeneous group of neoplasms including carcinoids, pancreatic neuroendocrine tumors, pituitary tumors, medullary thyroid carcinoma and phaeochromocytomas. the symptoms and the outcome of nets differ considerably between patients depending on several factors. by labelling tracers with a radioisotope, the tracer acts as a carrier to deliver the radioa...

this paper presents four cases of abnormal soft tissue activity in the bone scan of patients with different lesions (lung inflammatory pseudotumor, pulmonary fibrosis, pulmonary metastatic osteosarcoma and metastatic hepatic carcinoma of colon).

background and objective: gliomas are the most common primary brain tumors. despite therapeutic advances, the majority of gliomas do not respond to either chemo or radiotherapy. cd117, the gene product of c-kit has been expressed in cells of glial tumors. because gastrointestinal stromal tumors (gists) that express cd117 respond dramatically to treatment with tyrosine kinase inhibitors, identif...

background : cd117 is a thyrosin kinase receptor encoded by c-kit proto-oncogene. it is expressed during normal development in some tissues and also in a subset of neoplasia especially gastrointestinal stromal tumors   (gists). treatment with thyrosin kinase inhibitors (e.g., imatinib) is useful in cd117- positive gists. the goal of this study is to investigate the expression of cd117 in glial ...

solitary plasmacytoma of bone is a rare malignant tumor mostly involving the axial skeleton. the tumor occurs in middle- aged or elderly people (mean age: 55 years) and has a high risk of progression to multiple myeloma. radiotherapy is the preferred treatment for this disease. we report a case of recurrent solitary plasmacytoma of the fourth lumbar vertebra in a 35-year-old male. the patient s...

echocardiography plays a fundamental role in the evaluation of patients with an intracardiac mass. the ability to distinguish tissue characteristics, location, attachment, shape, size, and mobility non-invasively, quickly, and without the use of ionizing radiation makes echocardiography the ideal diagnostic modality. with careful attention to mass location and morphology, and appropriate applic...

purpose : to report clinical aspects of choroidal metastasis at a referral ocular oncology center methods : we reviewed the records of all patients with choroidal metastasis referred to an ocular oncology referral center over a 10-year period retrospectively. the study was performed to identify and analyze clinical presentations and features of patients with choroidal metastasis. results : a to...

background gastrointestinal stromal tumors (gist) are the most common mesenchymal tumors of the gastrointestinal (gi) tract. they are usually c-kit positive and seen slightly more common in men. these tumors are seen in the gi tract from the esophagus to the anus with occasional invasion or metastasis. method in this retrospective study, we evaluated the prevalence of c-kit positive stromal tum...

in this study, 22 patients (15-75 years old) were selected and transferred to ct scan for tumor ablation. for ablations, after prep and drep under the local anesthesia and mild sedation in proper position, small incision made and special needle inserted and guided by proper direction to the core of the tumor. then, laser probe inserted through the needle and laser energy delivered. although we ...
