Computed tomography (CT) of the pelvis demonstrated a 2.5 cm tumor at the left posterolateral wall and a 3.5 cm tumor at the left lateral wall of the bladder (Fig. 1).
Tumor have an epitheloid and sarcomatoid areas (H&E x 200).

These tumors were composed of sarcomatoid components and also carcinomatous components with high grade cellular atypia, and spindle cells and epihleloid cells were scattered within the tumor (Fig. 2).
(A) Diffuse vimentin positivity of tumor cells (Vimentin x 200), (B) and cytokeratin positivity of bladder (Cytokeratin x 200).
