cysts are caused by inflammatoryblockage of the sebaceous gland ducts and
are small, smooth, nodular masses, usually arising from the inner sur-faces of
the labia minora and majora, that contain cheesy, sebaceous material. They may
be easily excised if their size or position is troublesome.
The round ligament inserts into
the labium majus, car-rying an investment of peritoneum. On occasion,
peritoneal fluid may accumulate therein, causing a cyst of the canalof Nuck or hydrocele. If such cysts reach

arise from the connectivetissue and smooth muscle elements of vulva and vagina
and are usually small and asymptomatic. Sarcomatous change is extremely
uncommon, although edema and degenerative changes may make such lesions
suspicious for malignancy. Treatment is surgical excision when the lesions are
symp-tomatic or with concerns about malignancy. Lipomas appear much like fibromas, are rare, and are also treated
by excision if symptomatic.

the labia majora, and is treated with excision.

warranted, depending on clinical suspicion.
