title: Successful management of a ruptured endometrial cyst in acute leukemia.
abstract: OBJECTIVE
  To report a case of acute abdomen due to rupture of ovarian endometrial cysts, manifested as a first symptom of acute leukemia.
  
  
  METHODS
  Case report.
  
  
  METHODS
  University hospital.
  
  
  METHODS
  A 28-year-old Japanese woman with acute abdomen.
  
  
  METHODS
  A diagnosis of rupture of endometrial cysts was made by ultrasonography and magnetic resonance imaging. A diagnosis of acute myeloid leukemia (FAB M5a subtype) was made by bone marrow aspiration.
  
  
  METHODS
  Remission-induction chemotherapy for leukemia was initiated. Meanwhile, endometrial cysts were managed expectantly. Once complete remission was achieved, laparoscopic surgery was attempted to remove ovarian cysts and abdominal fluid.
  
  
  RESULTS
  Patients tolerated laparoscopy with favorable postoperative course. Consolidation chemotherapy commenced without substantial delay.
  
  
  CONCLUSIONS
  Accurate diagnosis, optimal timing of surgery, and minimally invasive surgery with laparoscopy enabled us to manage this high-risk case to a favorable outcome.
