Leiomyoma enucleated from a uterus. External surface on left; cut surface on right. Micrograph of a small, well-circumscribed colonic leiomyoma arising from the muscularis mucosae and showing fascicles of spindle cells with eosinophilic cytoplasm and elongated, cigar-shaped nuclei Immunohistochemistry for β-catenin in uterine leiomyoma, which is negative as there is only staining of cytoplasm ...
It can be linked with endometriosis, [12] but studies looking into similarities and differences between these two conditions have conflicting results. [ 13 ] The pathogenesis of adenomyosis still remains unclear, but the functioning of the inner myometrium, also called the junction zone (JZ), is believed to play a major role in the development ...
Women with uterine adenomyomas (focal adenomyosis) more commonly have co-existing endometriosis and a higher likelihood of infertility compared to women presenting with diffuse adenomyosis. However, a causal link between adenomyomas and the development of infertility has not been established, and further investigation is needed. [2]

When laparoscopy is used for diagnosis, the most common cause of dysmenorrhea is endometriosis, in approximately 70% of adolescents. [17] Other causes of secondary dysmenorrhea include leiomyoma, [18] adenomyosis, [19] ovarian cysts, pelvic congestion, [20] and cavitated and accessory uterine mass. [21]
Uterine fibroids, also known as uterine leiomyomas, fibromyoma or fibroids, are benign smooth muscle tumors of the uterus, part of the female reproductive system. [1] Most people [ note 1 ] with fibroids have no symptoms while others may have painful or heavy periods . [ 1 ]
Endometriosis: growth of the uterine lining outside the uterine cavity. This inappropriate tissue growth can lead to pain and bleeding. [4] Adenomyosis: a form of endometriosis, where the uterine lining has grown into and sometimes through the uterine wall musculature. This can thicken the uterine walls and also contribute to pain and bleeding.
The incidence of the mutation is between 1 in 10,000 and 1 in 15,000 births. By age 35 years, 95% of individuals with FAP (>100 adenomas) have polyps. Without colectomy, colon cancer is virtually inevitable. The mean age of colon cancer in untreated individuals is 39 years (range 34–43 years). [13]
