case_images: The tumor was well-circumscribed and protruding outside the renal contour, and no clear enhancement was identified in the arterial phase (Fig. 1).
case_images: Venous phase computed tomography. The tumor showed marginal uneven enhancement in this phase.

case_images: However, marginal uneven enhancement was observed in the venous phase (Fig. 2).
case_images: Tumor was composed of small, elongated cords or tubules, in a tightly packed arrangement (hematoxylin and eosin; magnification, x10).

case_images: The tumor was composed of small, elongated cords or tubules, in a tightly packed arrangement (Fig. 3).
case_images: Myxoid stroma was interspersed among the tubular cells (hematoxylin and eosin; magnification, x40).

case_images: Myxoid stroma was shown to be interspersed among the tubular cells (Fig. 4), and appeared to exhibit slender tubular spindle cell-like structures (Fig. 5).
case_images: Tumor cells were smaller and cube-shaped or oval, with single small eosinophilic nucleoli and low-grade nuclei (hematoxylin and eosin; magnification, x40).

case_images: The myxoid stroma was stained by acidic mucus (Fig. 7).
case_images: CK7 showed positive expression in tumoral cells (magnification, x20).
