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 ]
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 ...
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.
Fibroid may refer to: Uterine fibroid or fibroid, a benign growth in the uterus composed of: Leiomyoma, a benign smooth muscle tumor that very rarely becomes cancer (0.1%) Fibroma or fibroid, a tumor of fibrous connective tissue usually found on the skin; Inflammatory fibroid polyp, in the colon
Some benign tumors are able to grow to a dangerous size because unlike other cells, “tumor cells have found a way to evade the normal life and death cycle of a cell — meaning they’ve learned ...
The fibroma cavernosum or angiofibroma, consists of many often dilated vessels, it is a vasoactive tumor occurring almost exclusively in adolescent males. The cystic fibroma (fibroma cysticum) has central softening or dilated lymphatic vessels .
Benign tumors have relatively well differentiated cells. They are often surrounded by an outer surface (fibrous sheath of connective tissue) or stay contained within the epithelium. Common examples of benign tumors include moles and uterine fibroids. Some forms of benign tumors may be harmful to health.
Illustration of uterine fibroids with examples of their possible locations. Uterine artery embolization (UAE, uterine fibroid embolization, or UFE) is a procedure in which an interventional radiologist uses a catheter to deliver small particles that block the blood supply to the uterine body.
