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 ...
Whether or not angiomyomas are a type of leiomyoma or a separate entity is disputed as of 2014. [3] Myomas are benign tumors of the uterus that can affect the fertility of a woman depending mainly on three factors: Size (cut off value 4-5 cm) Number; Location (they can be intramural, subserous or submucous).
Intramural fibroids are located within the muscular wall of the uterus and are the most common type. [22] Unless they are large, they may be asymptomatic. Intramural fibroids begin as small nodules in the muscular wall of the uterus. With time, intramural fibroids may expand inwards, causing distortion and elongation of the uterine cavity.
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.

Leiomyomas do not typically require treatment unless they cause pain. [6] The skin lesions may be difficult to treat as they tend to recur after excision or destructive treatment. Drugs which affect smooth muscle contraction, such as doxazosin , nitroglycerine , nifedipine and phenoxybenzamine , may provide pain relief.

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.
