Abstract: Parasitic myomas are an infrequent type of myomas that appear in abdominal cavity. The incidence of this
pathology has increased over the past years. There has been many hypothesis about the pathogenesis. One
of the most recent ones is in relation to the start of laparoscopic morcellation at myomectomy or
hysterectomy to treat uterine myomas due to the small fragments that can be detached during the procedure
and that implant themselves in the abdominal cavity. Parasitic myomas, in most cases, are asymptomatic,
but it can cause an unspecific abdominal pain, menstrual disturbances, dyspareunia and other gynecological
symptoms. Physical exploration in patients is often also normal. The correct identification of parasitic
myoma by image tests, such as transvaginal ultrasound, CT or MRI, is still complicated because it is difficult
to diagnose due to the unspecific radiological characteristics that show up. CT and MRI give information
about the location that could be useful during the surgery. Usually the diagnosis is an accidental finding
during an abdominal surgery done for another reason and the histology of the piece is what gives the
definitive diagnosis. We present a case of a 32-year-old woman, asymptomatic, after a transvaginal
ultrasound is diagnosed a retroperitoneal tumor. The tumor was removed by laparoscopic surgery and the
patient had a favourable recovery. The histopathology of the tumor was a parasitic myoma.Keywords: Parasitic myoma, morcellation, laparoscopic, endometrial cysts
