A benign neoplasm characterized by the presence of a glandular and a mesenchymal (fibromyomatous) component. It occurs in the uterine corpus and the cervix. A variant of adenomyoma associated with glandular architectural complexity is called atypical polypoid adenomyoma. Simple polypectomy is usually curative. Atypical polypoid adenomyoma may recur following polypectomy.
