Extrauterine fibroids: a diagnostic challenge and a long-term battle

Abstract

Extrauterine fibroids often present a diagnostic challenge due to the unusual locations they arise from. We present a series of rare extrauterine fibroids. In recent years, these fibroids have been associated with previous morcellated hysterectomies or myomectomies. Our series of six patients were found to have extrauterine fibroids (confirmed through histology) and underwent open hysterectomy and open or laparoscopic myomectomy. Four had undergone previous laparoscopic myomectomies while the other two had no previous intra-abdominal surgeries. Postsurgical occurrence may be caused by incomplete removal of morcellated fibroid tissue. Spontaneous occurrence can be associated with congenital Müllerian system defects. Extrapolating from this hypothesis, we recommend physicians to make sure that counselling for extrauterine seeding and dissemination of unexpected malignancy is undertaken in cases of minimally invasive surgeries where morcellation is expected. Long-term tumour surveillance is thus essential in such instances.
