Robotic-assisted laparoscopic removal of dermoid cyst mimicking an enlarged cystic mass in the seminal vesicle.

Introduction: Isolated seminal vesicle cysts not associated with Zinner syndrome is a rare disorder that can present initially with urinary obstructive symptoms or nonspecific groin pain.

Case Description: We present the uncommon case of a dermoid cyst mimicking a seminal vesicle cyst treated with robotic-assisted laparoscopic seminal vesiculectomy.

Conclusion: For dermoid cysts, surgical excision is the gold standard of treatment with a high cure rate and little risk of regrowth if spillage is avoided and full resection is completed.
