We report a case of a 23-year-old male with complaints of low backache and hip pain radiating to the left inguinal region for four months. Radiology findings were suggestive of a neurogenic tumour. Cytomorphology, histomorphology and immunohistochemistry evaluation were done. Diagnosis was consistent with ES\/pPNET. Careful correlation between clinical history, cytomorphology, histopathology, immunohistochemical and molecular analysis can help to distinguish primary spinal ES\/PNET from other primary spinal tumours and will help clinicians to start treatment at the earliest.<\/jats:p>","DOI":"10.1177\/09727531231190979","type":"journal-article","created":{"date-parts":[[2023,9,15]],"date-time":"2023-09-15T02:36:21Z","timestamp":1694745381000},"page":"251-255","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":8,"title":["Primary Spinal Intradural Extramedullary Ewing\u2019s Sarcoma\/Peripheral Neuroectodermal Tumour Masquerading Clinically as a Neurogenic Tumour: A Case Report and Review of Literature"],"prefix":"10.1177","volume":"30","author":[{"given":"B.
