Abstract

We herein report a case of paraganglioma arising from the urinary bladder in a 67-year-old woman. Her chief complaint was gross hematuria. However, she didn't manifest any other catecholamine-associated symptoms such as hypertension, palpitation and micturitional attack. Grossly, the tumor revealed bilobular external appearance with foci of ulceration and hemorrhage. The cut surface showed pinkish yellow homogeneous soft tissue. Microscopically, the tumor was composed of polygonal cells with basophilic granular plump cytocopic study, numerous membrane-bound electron dense granules were noted in the cytoplasm.
