case_images: Gross and microscopic view of UTROSCT. a: Gross view of hysterectomy specimen showing a gelatinous grayish white tumor confined to the myometrium. b: Microscopic section of the tumor showing anastomosing cords and trabeculae with myxoid background. c: Tumor interface with myometrium revealing invasive borders of the tumor. d: High power microscopic section of the tumor showing round to oval cells with vesicular nuclei and pale cytoplasm.

case_images: Fig1
case_images: Cut surface of the tumor was gelatinous and grayish white (Figure  1a). Microscopic sections of the tumor revealed anastomosing trabecule and cords of cells with retiform architecture at places (Figure  1b). Tumor showed focally invasive borders (Figure  1c). Tumor cells showed vesicular nuclei with inconspicuous nucleoli and moderate amount of pale cytoplasm (Figure  1d).
case_images: Immunohistochemical stains of UTROSCT. a: Vimentin showing diffuse strong positivity in tumor cells. b: CD99 revealing diffuse positivity in tumor cells. c: S100 immunostain with diffuse expression in tumor cells. d: Cytokeratin stain showing focal expression in tumor cells.

case_images: Fig2
case_images: Tumor cells showed diffuse positivity for vimentin (Figure  2a), CD99 (Figure  2b) and S100 (Figure  2c) stains. Focal positivity was noted with pancytokeratin immunostain (Figure  2d) and occasional cells showed desmin positivity.
