Case Reports
Ewing's sarcoma and peripheral primitive neuroectodermal tumor in adults: different features of a rare neoplasm.
In adults, peripheral primitive neuroectodermal tumors (pPNETs) represent a rare and heterogeneous group of neoplasms exhibiting neuronal and glial differentiation. ⋯ As tumors of the EWS/pPNET family behave aggressively, rapid diagnosis is warranted. Since diagnosis of EWS/pPNET requires ancillary studies, it is necessary to consider it even in adult patients.
