A 45‐year‐old multipara woman was referred due to the rapid enlargement of an asymptomatic pelvic mass that was detected during a regular check up. She had undergone laparoscopic‐assisted myomectomy 15 years previously. At the time, the uncontained extraction of an intraligamental myoma with electric power morcellation had been performed. Multimodal imaging revealed a heterogeneous mass in the vesicouterine pouch that was found to be supplied by the left gastro‐omental and superior vesical arteries. Although malignancy could not be completely denied, parasitic peritoneal myoma with myxoid degeneration was the most probable diagnosis. Single‐port laparoscopic excision of the peritoneal mass was performed along with laparoscopic‐assisted vaginal hysterectomy and bilateral salpingo‐oophorectomy. The excised peritoneal mass was placed into a retrieval bag and extracted through the vagina. The pathological diagnosis was a parasitic peritoneal myoma with myxoid degeneration. The postoperative course was uneventful, and there was no recurrence of parasitic myoma in the 1‐year follow up after surgery.
