Primitive neuroectodermal tumors (PNETs) are fast-growing undifferentiated tumors that share a common cell of origin. Primitive neuroectodermal tumors constitute less than 1% of all primary spinal tumors. They are further classified into central and peripheral types. Peripheral PNETs are considered to belong to Ewing's sarcoma family of tumors. After the advent of immunohistochemistry and cytogenetic analysis, differentiating central and peripheral PNETs becomes possible. We are reporting the second case of extradural peripheral PNET occurring in the cervical spine after Pinelopi et al. Though rare, primary PNET should be considered as differentials in an adult patient presenting with a spinal mass lesion. Surgical excision followed by chemoradiation is the treatment of choice with 5 years survival of about 50%
