Video Objective The objective of this video is to describe the presentation, diagnosis and surgical approach to parasitic leiomyoma. We describe a case report of a postmenopausal patient who presented with incidental adnexal masses, underwent a diagnostic laparoscopy and was ultimately diagnosed with parasitic leiomyoma. We discuss the differential diagnosis, symptomatology, origin and epidemiology of this rare diagnosis. Setting A university tertiary care hospital. Interventions This is a case report of a patient with an incidentally diagnosed adnexal mass that was found to have parasitic leiomyoma. Conclusion Parasitic leiomyoma is an unusual variant of fibroid presentation. There are several hypotheses regarding their development, most importantly following morcellation after laparoscopic myomectomy. Others include the possibility of pedunculated fibroids that detach from the uterus and latch onto nearby viscera. This case illustrates the incidental finding of a parasitic leiomyoma, appropriate workup and differential diagnosis. We also elaborate on the surgical technique for removal of parasitic leiomyomas. We conclude that parasitic leiomyoma should be on the differential diagnosis for adnexal masses.
