Abstract
The increasing number of prostatic biopsies, performed for the investigation of patients at risk of prostate cancer, will result in the more frequent identification of uncommon forms of prostatic pathology. Amyloidosis is a disease characterized by the extracellular deposition of insoluble amyloid fibrils, and may be either systemic or localized. Localized amyloidosis of the prostate is very rare. Herein, we report the case of a 34-year-old man with localized amyloidosis of the prostate, which was found via a transrectal ultrasound-guided prostatic biopsy due to an increased serum prostate-specific antigen level.
