Title:
Blue Nevus of the Prostate: Is It Truly a Rare Lesion?
Authors:  Nataniele Piol, M.D., Bruno Spina, M.D., Riccardo Banchero, M.D., Massimo Maffezzini, M.D., and Carlo Toncini, M.D.
  In reference to the 2 recently published cases of multifocal blue nevus of the prostate,1,2 we have 2 further cases of this lesion to add to the literature. The first one is a 69-year-old man who suffered from a residual prostatic adenocarcinoma after internal radiation therapy. A radical prostatectomy and bilateral pelvic lymphadenectomy was then performed. Histopathological examination of the whole prostatic gland revealed a residual adenocarcinomatous component and a bifocal blue nevus of the prostate characterized by exclusively stromal aggregates of fusiform and dendritic cells containing melanin pigment (Figure 1).
