Large parasitic myoma post laparoscopic subtotal hysterectomy with morcellation: Case report and literature review

Parasitic myomas comprise a rare manifestation of leiomyomas. The exact prevalence of parasitic myomas is unknown, and fewer than 100 cases have been previously reported in the literature. In recent years, there has been an increase in reports of parasitic myomas, the majority of which, following previous uterine operative procedures, are mainly myomectomy-or hysterectomy-related involving tissue morcellation. Case: A 46-year-old woman (gravida 5 para 4), presented with a large abdominal mass, diagnosed postoperatively as multiple parasitic myomas, with one of them being especially large, 8 years after a laparoscopic subtotal hysterectomy using tissue morcellation. She underwent an exploratory laparotomy. Pathologic findings confirmed the presence of leiomyoma. Results: The patient's post-operative hospitalization was uneventful, and she was discharged 3 days post operation. Conclusions: Postmorcellation parasitic myomas comprise an increasingly reported novel entity, which is most commonly iatrogenic. Surgeons should take adequate preventative measures in order to decrease occurrences of these myomas.
