Primary malignant ectomesenchymoma of the orbit.
Malignant ectomesenchymoma (MEM) is a rare soft tissue tumour believed to arise from a pluripotential migratory neural crest cell and composed of both a mesenchymal element (most often rhabdomyosarcoma) and a neuroectodermal element (often neuroblastoma). Reported sites of origin are the abdomen, perineum or scrotum, the extremities, the middle ear, nasopharynx, face, and neck. We report the fi...

متن کاملFrequent epidermal growth factor receptor gene mutations in malignant pleural effusion of lung adenocarcinoma.
Malignant pleural effusions (MPEs) are often observed in lung cancer, especially adenocarcinoma. Epidermal growth factor receptor (EGFR) gene mutations are usually detected in lung adenocarcinoma. The purpose of the present study was to investigate the EGFR mutation rate in MPEs of lung adenocarcinoma. Between June 2005 and December 2006, 136 MPEs from lung adenocarcinoma were collected for EGF...
متن کاملPrimary intracranial malignant ectomesenchymoma in pineal region: a rare case report and review of literature
Primary intracranial malignant ectomesenchymoma (MEM) is a rare proliferative disorder that only occasionally involves the central nervous system. We presented a 16-year-old case of primary MEM located in pineal region. The patient was treated by total surgical resection followed by radiation and experienced no recurrence during the 6-month follow-up. The clinicopathological features of this ca...
متن کاملFrequent ATRX, CIC, FUBP1 and IDH1 mutations refine the classification of malignant gliomas
Mutations in the critical chromatin modifier ATRX and mutations in CIC and FUBP1, which are potent regulators of cell growth, have been discovered in specific subtypes of gliomas, the most common type of primary malignant brain tumors. However, the frequency of these mutations in many subtypes of gliomas, and their association with clinical features of the patients, is poorly understood. Here w...
