Light microscopic examination of the uterine sex-cord-like tumor revealed a highly cellular tumor tissue with no specific differentiation, consisting of solid nests and anastomosing cords and a few pseudo-tubular structures. The vacuolated cytoplasm of the lipid-rich cells proved vimentin-positive, but desmin- and keratin-negative. The coexistence of the two variants of endometrial stromal tumor was interpreted as arising from endometrial stroma or multipotential uterine mesenchyme that showed a diverse differentiation toward ovarian sex-cord stroma and uterine smooth muscle with interspersed stromal cell clusters.en10.3109/00016349209021080info:eu-repo/semantics/closedAccessENDOMETRIAL STROMAL TUMORUTERINE TUMOROVARIAN SEX-CORD-LIKE TUMORSTROMOMYOMAArticle715390393WOS:A1992JM035000151326218N/A
