title: Adult primary pulmonary primitive neuroectodermal tumor: molecular features and translational opportunities.
abstract: Primitive neuroectodermal tumors (PNET) arising directly from the lung are very rare but particularly aggressive neoplasms. We report a case of a 31-y-old man with primary pulmonary neuroectodermal tumor. We review the clinical as well as pathological features. As typical for these tumors, the diagnosis was initially delayed in our patient and prognosis was poor despite aggressive surgical resection, postoperative chemotherapy and local irradiation. Recent biological insights have revealed unique chromosomal translocations crucial to the pathogenesis of these tumors, most notably the EWS-FLI-1 translocation. We provide an overview of the molecular features of the Ewing Sarcoma Family of Tumors (ESFT) including PNET and their potential implications for therapeutic targeting.
