Primary Localised Amyloidosis of Urethra Presenting as a Penile Stricture.

Amyloidosis is characterized by the deposition of fibrillar proteins by either plasma cells or derived from circulating proteins, the former especially involved in pathogenesis of localised amyloidosis. We describe a case of primary localised amyloidosis involving the urethra, in a 54-year-old diabetic patient, presenting with symptoms of stricture. Though a rare cause, in a patient with clinical diagnosis of urethral stricture, one of the differential diagnosis to be ruled out is primary urethral amyloidosis. [ABSTRACT FROM AUTHOR]
