[Primary hepatic localization of the PPNET (primitive peripheral neuroectodermal tumors). Case report].

Our purpose is to study, through the case of a patient operated for right hepatic tumour, the clinical, radiological, anatomopathologic and therapeutic aspects of the peripheral primitive neuroectodermal tumours (PPNET). This tumour (PPNET) is a neoplasm belonging to the Ewing's family tumours, whose histology is similar. Its diagnosis requires the contribution of histopathology, immunohistochimy and cytogenetic studies. The primary hepatic localization of this rare tumour (our case), has never been reported. The treatment, in theory copied on that of the Ewing's sarcoma, is complex and not yet codified, which makes it another disappointing aspect of this disease whose prognosis remains dark.
