title: [A parasitic myoma: unexpected finding after laparoscopic hysterectomy].
abstract: During laparoscopic hysterectomy the uterus can be morcellated in order to remove it from the abdominal cavity. This technique carries a risk of tissue fragments being retained in the abdomen with recurring growth in the future.
  
  
  METHODS
  A 48-year-old woman with a history of hysterectomy presented with a swelling in her lower abdomen. Ultrasound investigation showed a solid tumour with a benign appearance. Differential diagnosis included an ovarian tumour or leiomyoma. Laparoscopic investigation revealed a preperitoneal tumour which was removed by laparotomy. Histologic examination showed a benign leiomyoma.
  
  
  CONCLUSIONS
  A patient with a history of hysterectomy is less likely to present with a myoma, however, in this case the diagnosis was correct. Due to the increasing use of a morcellator in laparoscopic hysterectomy in recent decades, we will be confronted with the diagnosis 'parasitic myoma' more frequently. Patients will have to be informed of the risk of this complication.
