The mitotic Aurora kinases, including Aurora-A and Aurora- B, are attractive novel targets for anticancer therapy, and inhibitory drugs have been developed that are currently undergoing clinical trials. However, the molecular mechanisms how these drugs induce tumor cell death are poorly understood. We have addressed this question by comparing the requirements for an efficient induction of apopt...

ovarian mixed germ cell tumors consisting of endodermal sinus tumor and immature teratoma are very rare and have been reported only in a few case reports. here we report a rare mixed germ cell tumor of ovary which was consisted of endodermal sinus tumor and immature teratoma components with an unusual intraabdominal location. patient was a 21 years old girl with the chief compliant of abdominal...

<p class="abstract">Osteosarcoma is the most common primary malignant bone tumor. Jaw an uncommon site. The etiopathogenesis still unknown. We present a case of 47-year-old female who underwent left partial maxillectomy as lesion increased in size over one month after removal tooth. Prior to surgery, computed tomography (CT) scan was suggestive maxillary sinus carcinoma and biopsy report ...

Primary cardiac sarcomas are rare and histologically diverse, with single tumors able to demonstrate histological heterogeneity. Consequently, they often misdiagnosed as other common tumors, such myxoma or metastatic malignancies. Incorrect diagnoses can result in incomplete surgeries, inadequate treatment regimens, early recurrence. In our experience, based on the diverse cytological character...

Squamous carcinomas of both human and rodent origin can undergo a transition to a more invasive, metastatic phenotype involving reorganization of the cytoskeleton, loss of cell adhesion molecules such as E-cadherin and acquisition of a fibroblastoid or spindle cell morphology. We have developed a series of cell lines from mouse skin tumors which represent different stages of carcinogenesis, inc...

background: giant cell tumor is a benign but locally aggressive bone neoplasm which uncommonly involves the skull. giant cell tumor (gct) of the sphenoid bone is relatively rare. in this report, we describe a tumor of the greater wing of left sphenoid bone. case presentation: a 31-year-old female was presented with headache, proptosis and diplopia of her left eye. cranial magnetic resonance ima...

p63 is a p53 homolog that is expressed in various normal epithelial tissues and epithelial malignancies. Its expression in mesenchymal lesions has not been examined in depth; therefore, we studied p63 expression by immunohistochemical analysis in 650 soft tissue tumors. We found that p63 expression is limited in soft tissue tumors. The majority of tumors studied were p63-, including all cases o...

Solitary fibrous tumors are uncommon spindle cell neoplasms originally thought to be restricted to the pleura. We describe a 62-year-old woman who presented with stridor and an anterior mediastinal mass. At thoracotomy, a 10.5 x 6.5 x 5.5 cm, circumscribed, firm mediastinal mass demonstrated no direct cardiac or pulmonary involvement. The tumor consisted of spindle cells organized in a patternl...
