Large parasitic myomas in abdominal subcutaneous adipose tissue along a previous myomectomy scar.

The incidence of iatrogenic parasitic uterine myomas associated with the use of a laparoscopic morcellator has been increasing over the past decade. Recently, we encountered a very rare case with a large parasitic myoma measuring 12 cm in diameter in the abdominal subcutaneous adipose tissue along an abdominal longitudinal surgical scar. The patient had twice undergone abdominal myomectomy for multiple fundal myomas. This is the first report describing a case with as large a parasitic myoma presenting in the suprafascial adipose tissue under the surgical scar after laparotomy. In such a case demonstrating a solid tumor of unknown cause after a gynecologic surgical procedure, a parasitic myoma must be included in the differential diagnosis.
