Contrast-enhanced computed tomography confirmed the USG findings by revealing well defined heterogeneously enhancing lobulated mass along the left lateral wall of the bladder [Figure 1].
(a) Section showing a highly cellular tumor arranged in sheets and composed of small cells with high nuclear-cytoplasmic ratio (H and E, x400). (b) High power view of tumor cells revealing scant cytoplasm, pleomorphic, angulated and hyperchromatic nuclei, finely granular chromatin, and inconspicuous nucleoli (H and E, x1000). (c and d) Tumor cells showing positivity for CD56 (c, x400) and synaptophysin (d, x400)

Tumor cells were arranged in sheets and showed scant cytoplasm, pleomorphic, angulated and hyperchromatic nuclei, fine granular chromatin, and inconspicuous nucleoli [Figure 2a and b]. IHC showed strong positivity of tumor cells for CD56 [Figure 2c] and focal positivity for synaptophysin [Figure 2d].
