ABSTRACT：Objective To explore the clinical diagnostic and therapeutic characteristics of peripheral primitive neuroectodermal tumor （PNET）.Methods A retrospective analysis was conducted on the clinicopathological data of a patient diagnosed with seminal vesicle PNET treated in our hospital.Relevant literature was retrieved in PubMed，Web of Science，and CNKI.The clinical features，pathological results，and treatment methods were reviewed.Results Including this case，a total of 6 cases were collected.This case underwent a radical cystectomy with transabdominal approach，bilateral seminal vesicle resection，pelvic tumor resection，and ileal bladder surgery.Postoperative pathology confirmed PNET.During the follow-up of 32 months，no local recurrence or distant metastasis recurred.Conclusion Seminal vesicle PNET is a rare tumor with high malignancy，rapid progression，and poor prognosis.The current diagnosis mainly relies on pathological biopsy and immunohistochemistry.Surgery is an effective treatment method.
