“…Independently of the usual uterine leiomyomas or leiomyosarcomas, a spectrum of intermediate uterine smooth muscle tumors has been documented, with overlapping characters. It remains unclear whether, at the level of pathogenesis, the intermediate tumors reflect transition from one marginal situation of common benign leiomyomas to the other extreme of uterine leiosarcomas [25,26].…”

Uterine myomas represent benign tumors of the myometrium, and they develop frequently in women of reproductive age. The frequency of uterine myomas increases with age until women reach the menopause. The study included patients with a myomatous uterus, in the reproductive age or peri-menopausal age, independently evaluating small and large myomas. Myometrial alterations in their direct vicinity were evaluated independently of the myomas. The study included evaluation of immunolocalization of two index proteins which participate in myoma cells growth control: Ki-67 nuclear antigen and caspase 3. In women of reproductive age, both in small and large myomas, elevated immunostaining of Ki-67 was noted in parallel to low levels of caspase 3 staining, which indicated the ongoing process of proliferation. In women of peri-menopausal age with small or large myomas, no Ki-67 immunostaining was detected, while staining of caspase 3 manifested low levels. Proliferation in reproductive age women myomas is higher than in the peri-menopausal age. (Folia Histochemica et
