Low-Grade Endometrial Stromal Sarcoma with Intravenous and Intracardiac Extension: A Multidisciplinary Approach

Figure 5

(a) Histopathological and immunohistochemical analyses show low-grade endometrial stromal sarcoma. The primary tumor in the uterus comprises CD10-positive short spindle cells resembling the stromal cells of proliferative endometrial tissue. Also spindle cells with abundant cytoplasm and ellipsoidal nuclei (α-SMA-positive cells) are mixed with the tumor cells. (b) The intracardiac tumor shows extensive smooth muscle differentiation. Main part is occupied with the spindle cells (α-SMA-positive). Scattered aggregates of small darker cells (CD10-positive) are still recognizable.
