Leio = Smooth

Myo = Muscle

-oma = a suffix for benign tumors

Leiomyoma can occur wherever the smooth mucles are , since these are the benign tumors of smooth muscle cells, like :

intestines

soft tissues

uterus , etc.

Histologically there are whorls of smooth muscle cells seen under the microscope.

Viva Voce :  1) Leiomyomas rarely very rarely metastasize. They occur mostly in women (uterus !!!) …. (2) Their malignant form is leiomyosarcoma which is differentitated from leiomyoma by two findings in Ten High Power microscipy field views as:

i) it is leiomyosarcoma if there are more than 10 mitoses without cellular atypism(normal smooth muscle cells)

ii) or if there are 5-10 mitoses with cellular atypism(not the normal cells).
