Localised amyloidosis of the glans penis presenting as a painless lump with progression after 10 years.

Primary amyloidosis of the genitourinary tract is uncommon, and isolated invasion of the glans penis is exceptionally rare Degos et al. (Bull Soc Fr Dermatol Syphiligr 68:159, 1961). We report a case of localised amyloidosis of the glans penis in a 40-year-old presenting as an asymptomatic penile mass which changed after 10 years prompting treatment. We believe this to be the longest interval recorded between clinical occurrence and histological diagnosis of primary penile amyloidosis.
