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 ...
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 ]
A myoma is a type of tumor that involves muscle cells. [1] There are two main types of myoma: Leiomyomas which occur in smooth muscle. [1] They most commonly occur as uterine fibroids, but may also form in other locations. Rhabdomyomas which occur in striated muscle. [1] [2] [3] They are rare tumors, occur in childhood and often become malignant.
Meigs syndrome may mimic other conditions, [4] since it is tumor arising from ovaries, pathology of any organs present in the abdomen may show a similar set of symptoms. . These include various gynecological disorders of the uterus such as endometrial tumor, sarcoma, leiomyoma (pseudo-Meigs syndrome); fallopian tube disorders such as hydrosalpinx, granulomatous salpingitis, fallopian tube ...
Uterine adenomyoma, the localized form of uterine adenomyosis, is a tumor composed of endometrial gland tissue and smooth muscle in the myometrium. [2] Adenomyomas containing endometrial glands are also found outside of the uterus, most commonly on the uterine adnexa but can also develop at distant sites outside of the pelvis . [ 3 ]
Fibroids (leiomyoma) — fibroids in the wall of the uterus cause increased menstrual loss if they protrude into the central cavity and thereby increase endometrial surface area. Coagulation defects (rare) — with the shedding of an endometrial lining's blood vessels, normal coagulation process must occur to limit and eventually stop the blood ...

Adenomyosis: Adenomyosis is a condition in which endometrial glands are present within the muscle of the uterus (myometrium), and the pathogenesis and mechanism by which it causes abnormal bleeding have been debated. [22] Leiomyoma (fibroids): Uterine leiomyoma, commonly termed uterine fibroids, are common, and most fibroids are asymptomatic. [4]
