Localized Secondary Amyloidosis of the Prostate

Abstract

Amyloidosis is an that is characterized the deposition of an abnormal proteinaceous material in extracellular tissue. Amyloidosis may be localized or systemic. Only about 6-9% all cases of amyloidosis are localized to a single organ system, and prostate is one of the rarest sites of involvement. Herein we report a localized secondary amylodosis of the prostate in a 73-year-old man. Amyloidosis is characterized by deposition of an abnormal proteinaceous material in extracellular tissue. It’s etiology is uncertain (1). Amyloidosis of the prostate is very rare. In recent years, with the increase in the number of prostate biopsies to exclude the malignancy, the number of the primary or secondary amyloidosis cases increased (2). Deposition of the amyloid can be localized or systemic (3). Herein we report a localized secondary amylodosis of the prostate in a 73-year-old man who underwent to transrectal ultrasound (TRUS) guided biopsy of prostate for suspected prostate cancer
