Primary localized cutaneous amyloidosis (PLCA) is caused by the extracellular deposition of amyloid material in the skin without other cutaneous or systemic organ involvement. PCLA is classified into lichen, macular,and nodular amyloidosis. Macular amyloidosis and lichen amyloidosis are named as biphasic amyloidosis when they are concurrently seen in a patient. The treatment of this disease is ...

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.
