A case is reported of an intracranial neoplasm of mixed mesenchymal and neuroepithelial (glial) origin occurring in the parieto-parasagittal region of the brain of a 19 year old man. A meningioma with liposarcomatous and psammomatous components comprised the mesenchymal part of the combined tumour. The neuroepithelial portion was composed of mixed ependymoma and astrocytoma. The combined neopla...

objectives: epithelial-mesenchymal transition (emt) is a fundamental stage in cancer metastasis and the presence of vascular invasion is a strong indication of the spread of the malignant tumor cells. regulation of the emt is a complex process in which several different transcription factors are involved. eomesodermin (eomes) as a member of the t-box gene family is an important component in the...

Primary hepatic angiosarcoma (PHA) is an exceedingly rare and aggressive neoplasm of mesenchymal origin. PHA makes a very small portion primary liver tumors conveys poor prognosis.

The coexistence of an epithelial lesion and a subepithelial lesion is uncommon. In almost all such cases, the coexistence of these lesions appears to be incidental. It is also extremely rare to encounter a neoplasm in the surface epithelium that overlies a benign mesenchymal tumor in the esophagus. Several cases of a coexisting esophageal neoplasm overlying a leiomyoma that is treated endoscopi...
