Parasitic myoma developing at the port site after laparoscopic myomectomy; a case report

Parasitic myomas occur especially after laparoscopic myomectomy and its incidence increases due to the use of morcellators. Parasitic myomas can rarely occur at the port entry site, being more commonly seen on the intestines, the omentum, the ureter, the bladder, and the diaphragm in different periods after surgery, with the average duration being 24 months. In this article, we present the case of parasitic myoma developing secondary to the port site in a 45-year-old nulliparous woman after the use of laparoscopic myomectomy and morcellation 8 years ago. The patient presented with complaints of pelvic pain and a palpable mass in the left trocar incision line, and an appearance compatible with multiple myomas in the subcutaneous tissue of the left trocar incision line. Besides, myomas were also observed in the mesentery of the rectosigmoid colon and at the uterus in the present study. Numerous and large myomas were observed in the uterus, in the mesentery of the rectosigmoid colon, on the left pelvic peritoneum, and under the skin corresponding to the port entrance. The pathological examination of the myomas excised was reported as leiomyoma. In this article, the diagnosis, the treatment, the possible risk factors, and the complications of myomas were discussed in the light of the literature.
