Abstract: Parasitic leiomyoma is a special type of uterine leiomyoma, and its incidence is very low. The causes may be related to the level of estrogen and progesterone, peritoneal metaplasia, genetic factors and iatrogenic factors. In recent years, the cases of secondary parasitic leiomyoma after laparoscopic surgery have been paid more and more attention. Because the clinical manifestations of most of the patients were non-specific, only some of the symptoms such as pelvic and abdominal pain were found during routine physical examination or other operations, so the actual incidence of the disease may be higher than the reported incidence. Making a good assessment before the operation, reducing the operation of the suspected malignant tumor, using a specimen bag, strictly abide by the principle of surgical non-tumor, using transvaginal or umbilical incision to remove the path, the surgical closure of the full washing of the abdominal cavity, instruments and punctures are the key methods to prevent the occurrence of parasitic leiomyoma.
