Primary spindle cell sarcoma of the seminal vesicle: A case report and literature review.

We report a case of primary seminal vesicle spindle cell sarcoma of a 57-year-old man who underwent multiple surgical treatment. The first diagnosis of a local hospital was a right seminal vesicle cyst, so only laparoscopic decompression was performed. Postoperatively, the patient gradually developed lower abdominal discomfort, frequent and urgent urination, dysuria and constipation.
