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...

some patients are more susceptible to hcc (like hbv, cirrhosis and …). in these patientsscreening imaging (ultrasound) is highly recommended. in positive cases next step would be 4-phasic ct scan or dynamic mri for confirm diagnosis and also staging. if there are typical signs of hcc (wash in, wash out), biopsy is not necessary in susceptible populations. gold standard treatment of hcc is surge...

Electron microscopic study of 1 1 spontaneous cat mammary tumors revealed the presence of virus-like particles in 5 of the tumors examined. In three tumors, spherical particles with two concentric shells surrounding an electron-lucent center were found budding from, or free within, the cisternae of the endoplasmic reticulum. In one tumor, spherical particles with four concentric shells surround...

Background: The female breast is subjected to a lifetime of hormonal controls, whose effect is evident at the time of menarche and during the menstrual cycle, pregnancy and lactation. Studies have reported multiple risk factors for breast cancer, some of which are a reflection of hormonally mediated events. The steroid receptors are also served as prognostic factors for evaluating status of mal...

Advanced imaging often reveals adrenal tumors and tumor-like conditions in both symptomatic and asymptomatic patients. When adrenal disease is clinically suspected, cross-sectional imaging can be helpful in evaluating the etiology of the patient's symptoms. When adrenal disease is incidentally identified, what the clinician and patient really want to know is whether the findings are benign or m...

Purpose of the study . To evaluate number cells with CD45 +/- phenotype expressing Toll-like receptors (TLRs) in tissues tumor, peritumoral area and resection line colon cancer (CC) various tumor locations. Materials methods The included 50 patients CC. All underwent surgery as primary treatment, tissue material was collected from patients. Expression TLRs (2, 3, 4, 8, 9) on + , - cell populati...
