meningioma is usually a benign central nervous system (cns) tumor. metastasis is rare; however if it does occur the most metastatic sites are the liver and lungs. here, two cases of cns meningioma with metastasis to cervical lymph nodes are reported. the first case, a 48 year-old man developed cervical lymph node metastasis nine years after primary tumor diagnosis. the second case, a 23 year-ol...

background: this study detected osteopontin (opn) and matrix metalloproteinase-7 (mmp-7) expressions to explore the roles of opn and mmp-7 in the occurrence, progression, and prognosis of nonsmall cell lung cancer (nsclc). materials and methods: a retrospective study was conducted on nsclc tissues ( n = 152; case group) and adjacent nonneoplastic lung parenchyma (adjacent to tumor >5 cm; n = 15...

a 60-year-old patient with testicular seminoma was referred for f-18 fdg pet/ct study to evaluate recurrence. in addition to hypermetabolic cervical, mediastinal and hilar lymph node tumoral metastases, segmental intense fdg uptake along the lumbar spinal cord suggestive of tumoral metastasis was noted which quite an unusual presentation is.  at the time of pet study the patient was symptomless...

dermatofibrosarcoma protuberans (dfsp) is very rare tumor of dermis layer of skin with the incidence of only 1 case per million per year. dfsp rarely leads to a metastasis (less than 5% have metastasis), but dfsp can recur locally. we publish a rare case of a recurrent dermatofibrosarcoma protuberans and its management with radical excision and interval skin grafting.

ba c k g r o u nd: skin  metastases occur  in  1-5%  of  solid  tumors  and  are  rarely the presenting sign of internal malignancies. certain features in skin lesions raise suspicion of metastasis from solid tumors. c a s e presentation: in this article a 61-year-old woman is presented with erythematous skin nodules  in  upper  abdomen  and  chest. histopathological evaluation  of  lesions sug...

Background: The First apoptosis signal (FAS) and First apoptosis signal ligand (FASL) genes initiate the apoptosis pathway, playing a central role in the tumor growth and metastasis. Gene polymorphisms including -1377 G/A in the promoter region of FAS and -844 C/T in the promoter region of FASL have shown to change the transcription activities of these genes. Methods: In this study we evalua...

background: the integrated educational system and service provision have involved the managers of iranian universities of medical sciences in different tasks and limited their access to adequate information for decision making. hence, it seems to be vital to adopt plans in order to provide necessary information for decision making. the current study was carried out to define the role of researc...
