Abstract:
Objective To explore the diagnostic and therapeutic strategies for primary small round cell malignant tumor of the seminal vesicle,so as to provide reference for the early prevention and treatment of this disease.Methods The clinical features,diagnostic approaches and treatment strategies of this case were reported based on literature review.Results A 26-year-old male patient was admitted due to"progressive dysuria complicated with painful urination and difficult defecating for two weeks."Pelvic MRI revealed a large,round,heterogeneous signal mass in the pelvic cavity(rectovesical pouch,posterior-superior to the prostate).Needle biopsy indicated a small round cell malignant tumor.Based on ancillary tests and clinical features,the case was diagnosed as advanced-stage malignancy with no opportunity for surgical intervention,and conservative treatment was initiated.The patient ultimately died two months after pathological diagnosis.A review of literature on seminal vesicle small round cell tumors over the past 20 years indicated that Ewing's sarcoma and rhabdomyosarcoma were the predominant subtypes.Conclusion Primary small round cell malignant tumor of the seminal vesicle is exceptionally rare,and clinically atypical with poor outcomes.While it is diagnostically and therapeutically challenging,early surgical intervention may significantly improve the prognosis and quality of life.
