Spontaneous vulvar hematoma during pregnancy: a case report.
BACKGROUND
Vulvar hematoma is a relatively uncommon occurrence. Most have been described resulting from traumatic injury in nonpregnant women or as an uncommon complication of childbirth. We describe a case of a spontaneous 6-cm vulvar hematoma that presented as unexplained vulvar edema in a 35-weeks-pregnant woman.


METHODS
A pregnant woman presented to the obstetrics triage unit with rapid onset unilateral vulvar swelling and no preceding traumatic event. A detailed physical examination and radiologic evaluation revealed a spontaneous vulvar hematoma as the cause. After incision and drainage of the hematoma, her edema resolved and the patient went on to have an uneventful vaginal delivery 4 weeks later.


CONCLUSIONS
Spontaneous vulvar hematoma is a rare event. Rapid recognition and treatment in this case allowed for complete recovery and enabled this pregnant woman to continue a normal pregnancy with uncomplicated spontaneous vaginal delivery.
