Symptomatic vulvar mucinous cyst: A case report and review of the literature.

Background: Vulvar mucinous cysts are rare, benign, noninvasive masses. They can be mistaken for cysts of Bartholin gland, Skene gland, vestibular, or canal of Nuck. Generally, they may be left untreated, but observed. However, if symptomatic, they may require surgical removal.

Case: We report a large vulvar mucinous cyst in a 29-year-old woman with no contributory medical history. Excision of the mass was performed because its size had begun to cause symptoms. The diagnosis of a mucinous cyst was based on radiological and clinicopathologic features. The patient developed a post-operative vulvar hematoma and was discharged 2 days after the surgery with a Foley catheter in place. Continued follow-up was maintained for the hematoma, which drained spontaneously and resolved without incident. There has been no recurrence of the cyst after completion of short-term surgical follow-up.

Conclusion: Vulvar mucinous cysts are rare masses. We present the diagnosis and treatment of a large vulvar mucinous cyst. The cyst was completely removed during surgery, but long-term surveillance for recurrence is currently being conducted.
