Abstract:
Amyloidosis of urinary bladder is a rare condition and may be primary or secondary in nature. A case of primary localized vesical amyloidosis (VA) in a 40-yr-old man is described which was confused with neoplasm by cystoscopic, urographic and other studies. Surgical specimens obtained by transurethral resection (TUR) were diagnostic and histologically revealed amyloid deposits in sub-epithelial stroma with chronic inflammatory and giant-cell reaction. Congo-red staining proved its amyloid nature. It was resistant to potassium permanganate (KMnO4) pretreatment, indicating it to be of the AL type.
