title: Robot-Assisted Laparoscopic Seminal Vesicle Cystadenoma Excision.
abstract: BACKGROUND
  Cystadenoma is an extremely rare benign tumor of the seminal vesicle. Diagnosis of these tumors and differential diagnosis from malignant ones may be challenging since most of the time symptoms do not occur. Management of these tumors remains debatable due to the limited data in the literature. We present the first robot-assisted laparoscopic excision of a cystadenoma of the seminal vesicle.
  
  
  METHODS
  A 48-year-old man presented with diminished ejaculate volume and a 3.5 cm right seminal vesicle mass, which increased its size at 6 cm after the 3-month period. Transrectal ultrasound-guided biopsy revealed no malignancy. Robot-assisted laparoscopic excision of the tumor was performed. Port placement was the same as robot-assisted radical prostatectomy. Operative time and estimated blood loss were 240 minutes and 200 mL, respectively. Patient was discharged on postoperative day 3 without any complications. Final histopathologic examination revealed cystadenoma of the seminal vesicle.
  
  
  CONCLUSIONS
  Surgical intervention may be considered when a cystadenoma of the seminal vesicle is diagnosed and symptoms or tumor growth occurs. Robot-assisted laparoscopic excision is an alternative in the management of these rare tumors.
