108 Leiomyomas are sometimes difficult to differentiate from ovarian lesions (see Chapter 112), or other uterine abnormalities such as leiomyosarcomas or adenomyomas. Differentiation of leiomyoma and adenomyoma (Table 108.1) is important as leiomyomas can be treated with a myomectomy, but adenomyomas require a hysterectomy. Submucosal leiomyomas in particular may be difficult to differentiate from adenomyoma.
