title: Giant multilocular cystadenoma of the prostate: a rare differential diagnosis of benign prostatic hyperplasia.
abstract: We report a case of giant multilocular cystadenoma of the prostate in a 43-year-old man. This is a rare benign entity of the prostate imitating symptoms of benign prostatic hyperplasia and originates from the prostate with extensive spread into the pelvis. Histologically, prostatic glands and cysts lined by cuboid to columnar epithelial cells with basally located nuclei are characteristic. Immunohistochemical staining is positive for prostate-specific antigen in the epithelial cells. Giant multilocular prostatic cystadenoma should be taken into account in the differential diagnosis in any case of a large cystic mass originating from the prostate.
