Primary isolated urethral amyloidosis.
We report an unusual case of primary amyloidosis isolated to the urethra in a patient with tender, periurethral masses and obstructive voiding symptoms. When not secondary to other phenomena, amyloidosis most commonly affects the skin, respiratory, and urinary tracts. Isolated amyloidosis of the urethra should be in the differential diagnosis of a patient with irregular strictures of the penile urethra, a clinical presentation consistent with urethral carcinoma, and no evidence of systemic disease.
