Severe recurrent endometriomas in a young woman with congenital von Willebrand disease.

ABSTRACT

The pathophysiology of severe endometriosis in young women remains unknown. Menorrhagia, or heavy and prolonged menstrual bleeding, is the most common symptom experienced by women with von Willebrand disease (vWD) and represents a possible risk factor for developing endometriosis. A 17-year-old woman affected by vWD presented with severe dysmenorrhea and heavy menstrual bleeding. After being diagnosed with multiple ovarian endometriomas, the patient underwent repeated surgeries due to suspicious appearance of recurrent pelvic masses. vWD may be a risk factor for developing severe endometriosis, and patients with endometriosis should be screened for vWD and other bleeding disorders. Ovarian endometriomas in such patients might present a more severe progression and unique ultrasound findings, mimicking malignancies.
