Case Reports

Background: Osteomyelitis of the pubic bone is a rare entity. Risk factors for infection of the symphysis pubis and osteomyelitis of the pubic bone include direct trauma, previous urogynecologic procedures, extreme physical exercise, and immunocompromised state. The treatment modalities range from conservative antibiotic treatment to extensive surgery.

Case: A 49-year-old woman with multiple sclerosis and borderline diabetes mellitus presented with bloody vulvovaginal discharge. The source was found out to be an ulcer located above the urethra with exposure of the underlying symphysis pubis. Intraoperative debridement of the ulcer followed by bone biopsies demonstrated osteomyelitis of the pubic bone. Prolonged intravenous antibiotics and 4 operative debridements were needed before the osteomyelitis was adequately addressed and the defect could be closed with a bulbocavernosus flap.

Conclusions: This is the first report of a severe case of osteomyelitis of the pubic bone arising from a vulvar ulcer.

Case report of osteomyelitis originating from a vulvar ulcer requiring several surgical debridements and closure with a bulbocavernosus flap.
