congenital granular cell tumor (cgct) is a unique benign tumor of soft tissue in newborns, which usually occurs on the anterior alveolar mucosa of the jaws. it is 8 to 10 times more prevalent in females than males. we present a case report of a 3-month-old female infant, who had a solitary mass on the anterior mandibular alveolar ridge. the lesion, which was histologically a congenital granular...

introduction: complete androgen insensitivity syndrome (previously called testicular feminization) is specified by a 46 xy karyotype and negative sex chromatin, bilateral undescended testes, female genitalia appearance, and lack of mullerian derivatives. discussion: our medline search revealed that this is the first reported case of bilateral sertoli–leydig cell tumor (slct) in androgen insensi...

desmoplastic small round cell tumor (dscrt) is a rare variant of sarcoma with a highly aggressive behavior. it usually affects abdominal cavity and has a male predominance. its correct diagnosis and treatment is sophisticated and requires an experienced multidisciplinary team. hereby we present a 25 yrold man from kerman province in 2013 with abdominal mass and ascites who underwent sonograghy ...

introduction: the aim of this study was to investigate the effect of the hsp-70 (heat shock protein-70) induction in the lysate of heat shocked tumor cells on splenocyte proliferation, nitric oxide production by peritoneal macrophages, and fibrosarcoma tumor size reduction in balb/c mice. material and methods: wehi 164 cells (mouse fibrosarcoma cell line) were injected subcutaneously into the r...

background and aims: plants as medicines have always played a vital role in human life. tumor necrosis factor alpha (tnf)-α is one of the macrophage-derived inflammatory cytokine with pleotropic effects in the inflammation process. some studies have been demonstrated that some of the echinops species have anti-inflammatory activity. in fact, echinops lasilepis is introduced as one of the native...

objective: recent evidences suggest that tumors arise from a small subpopulation of cells, the cancer stem cells (cscs) or tumor initiating cells. cscs are able to resist the conventional methods of cancer therapy due to existence of abc transporters on their surface. this leads to csc resistance and maintenance resulting in post-treatment relapse and metastasis. therefore, precise identificati...

background: although giant cell tumor (gct) is considered to be a primary benign bone tumor, its aggressive behavior makes its diagnosis and treatment, difficult and challenging. this is especially true in distal radius where gct appears to be more aggressive and difficult to control locally. we report our clinical outcome of en-block resection and reconstruction with non-vascularized fibular a...

objective(s): the oct4b1, as one of oct4 variants, is expressed in cancer cell lines and tissues more than other variants and plays an important role in apoptosis and stress (heat shock protein) pathways. the present study was designed to determine the effects of oct4b1 silencing on expressional profile of hsp40 gene family expression in three different human tumor cell lines. materials and met...

Desmoplastic small round cell tumor is a rare malignant tumor that occurs primarily in young males. Here, a case of small round cell tumor in an adult male successfully treated with a curative concurrent chemoradiotherapy is presented. A 58-year-old man had an intrapelvic tumor. Surgical resection was attempted, but the tumor was unresectable. Needle biopsy was performed and the diagno...

cancer immunotherapy (passive or active) involves treatments which promote the ability of the immune system to fight tumor cells. several types of immunotherapeutic agents, such as monoclonal antibodies, immune checkpoint inhibitors, non-specific immunomodulatory agents, and cancer vaccines are currently under intensive investigation in preclinical and clinical trials. cancer vaccines induce pe...
