Rare Case of Osseus Metaplasia in a Detached Remnant Leiomyoma Following Hysteroscopic Myomectomy.

Uterine leiomyoma is the most common benign tumor of the uterus, affecting reproductive-age women. Although women with uterine fibroids are commonly asymptomatic, in symptomatic patients, hysteroscopic myomectomy is considered the first-line surgical treatment for intracavitary fibroids in women who wish to maintain fertility.  Osseous metaplasia in uterine fibroids is the transformation of fibroids cells into pure mature or immature bone. It is rare, and few case reports present with osseous metaplasia in uterine fibroids. This is the first report in the literature of osseous metaplasia in a remnant fibroid after hysteroscopic myomectomy. Every effort should be attempted to ensure complete retrieval of the detached fibroid remnant after hysteroscopic resection, as this might decrease the risk for subsequent surgeries.
