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.
It consists of an abrupt transition between necrotic cells and preserved cells. Ghost nuclei from necrotic cells are often seen, but inflammatory cells are uncommon. Hyalinizing necrosis is more common in leiomyomas. It consists of a zone of hyalinized collagen between dead cells and preserved cells, commonly eosinophilic.
The first of these "subclassification systems" was for leiomyomas (Figure 3), recognizing their prevalence and the already existing classification system for submucous leiomyomas first published by Wamsteker et al. [11] and then adopted by the European Society of Human Reproduction and Embryology (ESHRE). Added was a category for submucous ...
Leiomyomata tend to grow during pregnancy but only the large ones causing endometrial cavity distortion could interfere with the growing pregnancy directly. [10] Generally, surgeons tend to stay away from operative interventions during the pregnancy because of the risk of haemorrhage and the concern that the pregnancy may be interrupted.
Genital leiomyoma can be symptomatic or asymptomatic and is dependent on the type of leiomyoma. In most cases, pain in the affected area or region is most common. For vaginal leiomyoma, vaginal bleeding and pain may occur. Uterine leiomyoma may exhibit pain in the area as well as painful bowel movement and/or sexual intercourse.
