Paragangliomas are tumours arising from extra adrenal chromaffin tissue. Paraganglioma of urinary bladder are extremely rare. They are usually diagnosed on histopathology and confirmed on immunohistochemistry. They are frequently misdiagnosed as urothelial carcinoma, especially the nested variant. We reported a similar case which was diagnosed as urothelial carcinoma(nested variant) and came to our institution for review of diagnosis. The patient presented with only complaint of painless haematuria for past one month. Excluding all other possible differentials, the final diagnosis of paraganglioma was rendered. The treatment is different and prognosis of paraganglioma is much better than urothelial carcinoma, hence an accurate histopathological diagnosis is of prime importance.
Keywords: paraganglioma, urinary bladder, urothelial carcinoma, IHC.
