Acute hemorrhage related to spontaneous rupture of an uterine fibroid: a rare case report. 
The authors present smooth muscle tumors of uncertain malignant potential (STUMP) diagnosis and surgical management of a spontaneously-ruptured degenerated uterine fibroids.  A 48-year-old nulliparous presented with a two-day history of abdominal pain, bloating, constipation, and menorrhagia.  Within eight hours, her distress level increased.  Computed tomography (CT) scanning of the abdomen showed a large, 31 x 25 cm solid-cystic lesion.  An emergency laparotomy was indicated.  Surgery revealed approximately 2,000 cc of blood and a 30 cm degenerated uterine fibroid with a fundal rupture, cystic, and solid components extending to the lower pole of the liver.  Pathology results noted mild nuclear atypia, six mitoses per ten high-power fields (hpf) and necrosis spread that was not coagulative with a STUMP diagnosis.  STUMP presents a problematic group of uterine smooth muscle tumors for any clinician.  In addition, STUMP can rarely cause acute complications like a rupture.  Therefore, prompt diagnosis and effective management are important.
