Ciliated vulvar cyst in the labia majora: A case report

Vulvar ciliated cysts are benign cysts lined with simple columnar ciliated epithelial cells that resemble Mullerian tissue. They are usually associated with pregnancy and exogenous progesterone use and, as such, are rare. They are usually asymptomatic unless their size increases enough to cause pressure symptoms. Patients with these cysts usually come to the doctor with aesthetic concerns, as they cause disfigurement of the vulva. A 21-year-old female presented with a cystic structure arising from the right labia majora of the vulva, with a length of about 5-6 cm, without any significant symptoms, except for the disfigurement of the external genitalia. The cyst was surgically excised, and the histopathological report confirmed the features of a benign Mullerian cyst lined by ciliated columnar epithelium. The cosmetic result was excellent, and the young patient felt relieved. Mullerian cysts arising from the labia majora are a rare finding, and the treatment is surgical excision. The excision not only cured but also restored the normal anatomy of the vulva. It also confirmed the histological diagnosis.
