case_images: Histological structure of biopsy material was represented by the fibrous and muscular bundles with the presence of spindle-shaped cells with eosinophilic cytoplasm (figure 1).
case_images: The microphotograph depicts a high level of vimentin cytoplasmic expression (vimentin, x100).

case_images: IHC study revealed a high level of cytoplasmic expression of vimentin (figure 2) and SMA (figure 3), which is an indicator of tumor growth of mesenchymal origin, in particular, of smooth muscle cells.
case_images: The microphotograph depicts a high level of smooth muscle actin cytoplasmic expression (smooth muscle actin, x100).

case_images: Also, there was a high expression of progesterone receptors (from 80% to 92%) (figure 4) and a low expression of estrogen receptors (from 30% to 42%) (figure 5).
case_images: A low level of estrogen receptors intranuclear expression is revealed (estrogen receptors, x250).

case_images: Also, there was a high expression of progesterone receptors (from 80% to 92%) (figure 4) and a low expression of estrogen receptors (from 30% to 42%) (figure 5).
case_images: Low proliferative activity (Ki67) is revealed (Ki67, x40).
