An adenomyoma is a focal region of adenomyosis resulting in a mass, which is difficult to distinguish from a uterine fibroid, although in general the degree to which the contour of the uterus is distorted is less marked in adenomyosis 2. Additionally, the 'mass' is poorly defined and blends with the surrounding myometrium. Uterine fibroids on the other hand often have a pseudocapsule of compressed myometrial tissue surrounding them 2

Some authors draw a distinction between focal adenomyosis and adenomyoma. Adenomyomas, they contend, are a focal form of adenomyosis which is not in direct continuity with the junctional zone of the uterus 5
