Leiomyoma Histopathology slides are listed below. Click on the photos to enlarge them.
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).
