Gross examination of the uterus as shown in the picture above reveals several rubbery white masses with a whorled appearance as seen in cases of Leiomyoma.
Leiomyoma are totally benign, and composed of smooth muscle, leiomyomas occur predominantly in the uterine wall. They may occur singly or in multiple locations within the uterus. Usually, these tumors produce no symptoms, but occasionally, they cause bleeding, pain, or infertility.
Leiomyomas are frequently referred to as “fibroids,”which is a misnomer since they are composed of smooth muscle, not fibrous tissue. Histologically, the tumor has a uniform appearance, with bundles of smooth muscle cells resembling those of the normal myometrium. The tumor cells are spindle shaped, and mitotic figures are rare as shown in the picture below.
