title: Systemic amyloidosis presenting with glans penis involvement.
abstract: Penile amyloidosis has been reported on many occasions in the literature, but all of these have been forms of primary cutaneous amyloidosis. Systemic amyloidosis presenting with a penile ulcer as the first manifestation has not previously been reported. We present two patients in whom an ulcer of the glans penis was the first complaint that led to a diagnosis of systemic amyloidosis. In both patients, lambda light chain type amyloid was showed immunohistochemically. Both patients presented with other manifestations of systemic amyloidosis, including nail dystrophy characterized by onycholisis, trachyonychia and onychoschizia.
