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 ...
Intravenous leiomyomatosis is a rare condition seen exclusively in women in which leiomyomata, benign smooth muscle tumors, are found in veins.The masses are benign-appearing but can spread throughout the venous system leaving the uterus and even cause death when growing into the heart from the IVC.

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. So-called adult rhabdomyoma has been ...
[1] [2] It is also associated with increased risk of uterine leiomyosarcoma. [3] The syndrome is caused by a mutation in the fumarate hydratase gene, which leads to an accumulation of fumarate . The inheritance pattern is autosomal dominant and screening can typically begin in childhood.
[1] [3] Someone can have one uterine fibroid or many. [1] It is uncommon but possible that fibroids may make it difficult to become pregnant. [1] The exact cause of uterine fibroids is unclear. [1] However, fibroids run in families and appear to be partly determined by hormone levels. [1] Risk factors include obesity and eating red meat. [1]
In 2019, a woman living in Bangladesh with a double uterus gave birth to three babies — first, a baby from one uterus, and then, 26 days later, twins from her second uterus.
If 5 or more mitotic figures are present in 10 high powered fields but the behavior still appears benign, may append “with significant mitotic activity”. Moderate to severe atypia without tumor cell necrosis atypical leiomyoma if < 10 mitotic figures per high power field or; leiomyosarcoma if ≥ 10 mitotic figures per high power field
