Endometriomas of the vulva

[Justin Bieber]

Vulvar endometriomas are rare, painful, blood-filled cysts that develop when tissue from the lining of the uterus (endometrial tissue) appears in the vulva.

Endometriomas may be painful, particularly during sexual intercourse and before and during menstrual periods.
Doctors can usually diagnose endometriomas during a pelvic examination.
Endometriomas in the vulva are surgically removed.

For unknown reasons, patches of tissue from the lining of the uterus (endometrial tissue) sometimes appear outside the uterus. This disorder is called endometriosis. Endometriosis rarely occurs in the vulva (the area that contains the external genital organs). It is more common in other locations, such as the ovaries.
Sometimes the endometrial tissue forms a cyst (endometrioma).
Endometriomas often develop at the site of a previous operation, such as an episiotomy (an incision to widen the opening of the vagina to help with delivery of a baby) or repair of a tear in the vagina or vulva that occurred during delivery.
