Abstract

Giant multilocular prostatic cystadenoma (GMPC) is a rare benign tumor involving the prostate gland. Microscopically, it masquerades phyllodes tumor or transitional zone hyperplasia. We report one case of GMPC arising from the prostate central zone (CZ), presenting with long-standing aspermia associated with seminal vesicle fibrous obliteration.

  Fig. 2 Microscopic finding of giant multilocular cystadenoma. (A) Tandem arrayed prominent intraluminal ridges and extensive arborizing complex glands. (B) Increased stromal cellularity projecting into dilated cystic space, giving the impression of mammary gland phyllodes tumor. (C) Seminal vesicle was obliterated by periluminal amyloidosis.
